LITHIUM IRON PHOSPHATE VS LITHIUM-ION: DIFFERENCES AND ADVANTAGES

When using power sources to run embedded components, it's not always simple to pop in a fresh set of batteries. Newer technologies, from smartphones to electric vehicles to portable power tools, require batteries that can hold a significant amount of energy, be lightweight enough to carry or move, and be safe for the user. Lithium batteries offer all these benefits for portable electronics, vehicles, medical equipment, and even grid energy storage. Lithium-ion and Lithium iron phosphate are two types of batteries used in today's portable electronics. While they both share some similarities, there are major differences in high-energy density, long life cycles, and safety. Most people are familiar with lithium-ion as they most likely own a smartphone, tablet, or PC. Lithium iron phosphate is a newer type of battery gaining recognition in the manufacturing industries due to its cost-effective materials and stability with high temperatures. Chemistries Of Lithium Iron Phosphate And Lithium-Ion Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C should provide 500mA for two hours, and at 2C it delivers 2A for 30 minutes. Lithium-Ion Lithium-ion can consist of two different chemistries for the cathode, lithium manganese oxide or lithium cobalt dioxide, as both have a graphite anode. It has a specific energy of 150/200 watt-hours per kilogram and a nominal voltage of 3.6V. Its charge rate is from 0.7C up to 1.0C as higher charges can significantly damage the battery. Lithium-ion has a discharge rate of 1C. ithium Iron Phosphate (LiFePO4) Lithium iron phosphate has a cathode of iron phosphate and an anode of graphite. It has a specific energy of 90/120 watt-hours per kilogram and a nominal voltage of 3.20V or 3.30V. The charge rate of lithium iron phosphate is 1C and the discharge rate of 1-25C. What Are The Energy Level Differences? There are significant differences in energy when comparing lithium-ion and lithium iron phosphate. Lithium-ion has a higher energy density at 150/200 Wh/kg versus lithium iron phosphate at 90/120 Wh/kg. So, lithium-ion is normally the go-to source for power hungry electronics that drain batteries at a high rate. On the other hand, the discharge rate for lithium iron phosphate outmatches lithium-ion. At 25C, lithium iron phosphate batteries have voltage discharges that are excellent when at higher temperatures. The discharge rate doesn't significantly degrade the lithium iron phosphate battery as the capacity is reduced. Life Cycle Differences Lithium iron phosphate has a lifecycle of 1,000-10,000 cycles. These batteries can handle high temperatures with minimal degradation. They have a long life for applications that have embedded systems or need to run for long lengths of time before needing to be charged. For lithium-ion, the higher energy density makes it more unstable, especially when dealing with higher operating temperature environments. It has a life cycle of 500-1,000 cycles as it can be negatively impacted based on the operating temperature of the electronics or working components. Long-Term Storage Benefits When it comes to storing unused batteries, it is important to pick a chemistry that doesn't lose its charge over long periods of time. Instead, the battery should give close to the same charge performance as when it is used for over a year. Both lithium iron phosphate and lithium ion have good long-term storage benefits. Lithium iron phosphate can be stored longer as it has a 350-day shelf life. For lithium-ion, the shelf life is roughly around 300 days. Safety Advantages Of Lithium Iron Phosphate Manufacturers across industries turn to lithium iron phosphate for applications where safety is a factor. Lithium iron phosphate has excellent thermal and chemical stability. This battery stays cool in higher temperatures. It is also incombustible when it is mishandled during rapid charges and discharges or when there are short circuit issues. Lithium iron phosphate does not normally experience thermal runaway, as the phosphate cathode will not burn or explode during overcharging or overheating as the battery remains cool. However, the chemistry of lithium-ion does not have the same safety advantages as lithium iron phosphate. Its high energy density has the disadvantage of causing the battery to be unstable. It heats up faster during charging as a lithium-ion battery can experience thermal runaway. Another safety advantage of lithium iron phosphate involves the disposal of the battery after use or failure. A lithium-ion battery made with a lithium cobalt dioxide chemistry is considered a hazardous material as it can cause allergic reactions to the eyes and skin when exposed. It can also cause severe medical issues when swallowed. So, special disposal considerations must be made for lithium-ion. On the other hand, lithium iron phosphate is nontoxic and can be disposed of more easily by manufacturers. Applications For Lithium Iron Phosphate And Lithium-Ion Lithium iron phosphate is sought after for any electronics or machines where safety and longevity are desired but doesn't need an extremely high energy density. Electric motors for vehicles, medical devices, and military applications where the technology will experience higher environmental temperatures. Lithium iron phosphate is also ideal for applications that are more stationary as the battery is slightly heavier as well as bulkier than lithium-ion, although it can be used in some portable technologies. Lithium iron phosphate may not be selected for applications where portability is a major factor due to its extra weight. For smartphones, laptops, and tablet devices, lithium-ion batteries are used. Any high-energy device that needs the best performance on the first day can benefit from the chemistry found on lithium-ion batteries. Besides looking for the right energy sources based on portability, safety and energy density, manufacturers also must consider the costs during the production of electronics as well as during disposal. Many manufacturers will select lithium iron phosphate as the cheaper battery alternative. The batteries cost less due to the safer iron phosphate chemistry as manufacturers don't have to spend more money to recycle the materials. Lithium Offering A Range Of Benefits Advances in battery technologies has placed lithium chemistry at the head of the pack for being the best power source for high energy use devices that are portable. It's long shelf life and the benefit in providing a continuous source of power over long periods of time is why both lithium-ion and lithium iron phosphate are reliable alternatives. Currently, lithium batteries are still on the pricey side when compared to nickel metal hydride an nickel cadmium batteries. Yet, the long life of lithium batteries can equal out the initial high costs. For manufacturers trying to decide whether lithium-ion or lithium iron phosphate will be ideal for applications, consider these key factors: -Highest energy density: lithium-ion -Good energy density and lifecycle: lithium iron phosphate -Stable chemical and thermal chemistry: lithium iron phosphate -No thermal runaway and safe when fully charged: lithium iron phosphate -Portability and lightweight characteristics: lithium-ion -Long life: lithium iron phosphate and lithium-ion -Low costs: lithium iron phosphate Also, take the operating environment into serious consideration as well as any vibration issues that may be experienced. These instances may influence a manufacturer's choices as the chemistry stability that lithium iron phosphate offers are superior than that of lithium-ion.

Best Fishing Places In Europe

There’s nothing quite like fishing for the first time in a new place. For any angler, whether aspiring or full of experience, fishing is a precious activity that helps them relax. What could be better for them than combining tourism and their favorite pastime? Fortunately for those who enjoy fishing, there are great places in Europe that feature a variety of fish. If you’re planning to make your next vacation all about fishing, we can help you decide where to go. Let’s have a look at our list of 5 best fishing Places in Europe to enjoy: 1. Fishing Places In Sweden If you want to fish in Sweden, you needn’t look much further than Stockholm for great fishing places. For example, Stromgatan is right in the middle of the city, and it has a great view. You can look upon the Swedish parliament building and the Gamla stan while fishing. Another urban place is the Hammarby Sjostad upon Hammarby lake, a popular neighborhood in Stockholm. It has plenty of great fishing places and is easily accessible from the city. However, if you want a more classic nature fishing experience, you won’t have to drive far from Stockholm. Ringsjon Lake offers some beautiful fishing places where you can catch whitefish and rainbow trout. Drevviken is another quiet lake close to Stockholm, similar to Ringsjon. A tremendous and sustainable place to fish, Drevviken Lake won’t disappoint you. You could also head to the Stockholm archipelago and the island of Galo, which is a true isolated paradise. You can camp and fish there to your heart’s content, enjoying the archipelago’s nature. 2. Fishing Places In France France is a beautiful country for just about any activity, so it’s no wonder fishing in France is also great. One of the most prominent fishing locations is Lac du Bourget, France’s deepest and largest lake. It’s an impressive place because it houses over 30 species of fish. Among them, trout, zander, pike, and perch stand out. The lake is truly a jewel of the Rhone-Alps region. Then there is the Bassin d’Arcachon on the south-western coast of France — for those who enjoy saltwater fishing. Beautiful sunrises, crystal-clear waters, and sea bass are just some of the things that you can expect at Arcachon. Anglers from abroad love Lake Der-Chantecoq, right in the heart of the Champagne region, relatively close to Paris. It’s a great place for beginners, although old pros frequent the lake because of giant carp. Other notable French places include La Rance River and Alder. Both are popular as great destinations to take your family on a fishing trip. 3. Fishing Places In Italy When in Italy, you might as well look for some of the best fishing places in Europe. The region of Le Marche offers some great fishing, especially at Cingoli, Pioraco, and Sefro. They’re some of the most beautiful Italian lakes for fishing, containing trout, pike, and carp, among other species. However, when it comes to lakes, there’s also Lake Como up north, with its pike and perch. Let’s not forget about the biggest Italian river, the Po. It houses giant catfish and big carps that would entice any angler. In Tuscany, the rivers are the most prominent fishing places. Lima and Sieve are great places to fish for trout and grayling. For those anglers who prefer fishing on the open waters, there are two great fishing places in Italy. The Egadi Islands of Sicily and the coast of Sardinia will both stun you with their beauty and the quality of fishing they provide. Look for blue-fin tuna and Sicilian swordfish in the Mediterranean, and amber-jack, snapper, and Garrick in the Tyrrhenian Sea. 4. Fishing Places In The UK The United Kingdom is a stunning place, offering some great fishing places in the unspoiled wild beauty of the isles. If you want an amazing catch, the UK might be the right place for you. But which place should you pick? One of the most prominent places in Dartmoor, Devon. With such an evocative name, you can’t fail to imagine the experience of fishing for hungry fish in dark streams. The river Tyne in Northumberland has a color that offers you a distinct advantage against the sea trout living there. That makes this river perfect for daylight fishing and the biggest sea trout catch. River Clettwr close to the border of England and Wales is going to be the most attractive place for adventurers. Look no further if you want to work hard for your catch in rough waters. The situation is somewhat more accessible at Strangford Lough, County Down. It’s the UK’s largest sea loch swarming with mackerel, pollock, and haddock, among others. Assynt might be the most awe-inspiring place of all — nestled under big mountains, with both saltwater and freshwater fishing options. Fionn Loch is a great place to fish for native brown trout. 5. Fishing Places In Germany Germany certainly deserves its place on the list of the best fishing places in Europe. With so many big rivers and lakes, it would be a wonder if it didn’t make the list. Some of the most popular locations for fishing in Germany have to include the Danube area. In the 8 kilometers long Bavaria Danube area, you can catch a vast diversity of fish. For more river fishing, the Rhine and the Elbe, especially at Baden-Wurttemberg and Sachsen-Anhalt, respectively, the experience is amazing. However, if you prefer lake fishing, there’s always lake Chiemsee and Lake Starnberg. Both are quite deep, with plenty of pike, trout, and bream. For all anglers with an itch to travel, there are ways to combine their two great loves. Europe offers plenty of places to make a great catch and enjoy nature and bustling cities alike.

Where Is Ice Fishing Most Popular?

Ice fishing is most popular in regions with cold winters, a lot of fresh water, and a lot of open space. This means vast areas of North America and parts of Europe, particularly Scandinavia. Ice fishing is popular in many of the more rural areas of the world. There are other factors that make it a favorite local pastime in certain areas as well. Cold Winters Means Good Ice Fishing The most important quality an area needs to have, of course, is cold winters. After all, ice fishing needs ice. For a lake to freeze, the temperature needs to get quite cold. You probably remember that water freezes at 32 degrees Fahrenheit (0 degrees Celsius). So, in areas that don’t get very cold during the winter, the water is not going to freeze. It takes time for lakes to freeze. Just because the temperature in an area gets below freezing for a couple of hours, that doesn’t mean the lakes are going to freeze. Water is more resistant to temperature change than air is. So, the temperature needs to be cold for a long while to get a lake good for ice fishing. The reason ice fishing is possible is that when ice forms, it floats above warmer water, insulating it and letting fish live on through the winter. Beneath a thick sheet of ice may be thousands of fish. Those who ice fish experience a unique kind of fishing and often have a lot of success. Naturally, ice fishing is only popular in areas where there are many lakes and rivers. There are some cold areas in the world that lack a lot of fresh water, so they are out of luck when it comes to fishing. Another necessary component of ice fishing’s popularity is a large amount of land that is legally open to fishing. Ice fishing is not an activity done within urban areas. There need to be lakes, a bit far from civilization, open to the public. That said, these spots are not necessarily hundreds of miles away from big cities, so ice fishing is still an activity people can spend a day doing and go home to sleep in their own beds. Also, rivers aren’t good for ice fishing because it is more difficult for flowing water to freeze than it is for still water. But this isn’t much of an issue when it comes to this question, because if there are rivers, there are going to be lakes somewhere along the way. Just remember this if you choose to go ice fishing. Popular Areas for Ice Fishing in North America I’ve described the general qualities of areas where ice fishing is popular, but what are some specific regions where it’s popular? In North America, there are many. A huge percentage of the United States has cold enough winters for lakes to freeze and for ice fishing to be popular. The West Coast is not one of these regions, though it is possible to ice fish in parts of California. Anything too Southern is a no-go, too, because even if some of these areas might get snow, the winters simply aren’t long or cold enough, generally. So while states like Alabama or Texas may have much fishing to offer, but ice fishing is not going to happen. Desert areas like Nevada and Arizona are not good for it either, and you can probably guess why: not enough water, and not cold enough. With all that said, that leaves an absolutely massive amount of land where ice fishing can happen. An online forum for ice fishing called iceshanty.com has people discussing ice fishing in dozens of states. Here is a list of all states for which they host active discussions for ice fishermen living or visiting there: If you are not from the U.S., you might not have heard of all of these states, which is part of what makes them so great for ice fishing: there are few people living there, so there is a huge amount of open land. One of the greatest experiences of fishing in the winter can be the quiet, and ice fishing in places like Wyoming or North Dakota will provide that. Other states like New York do have big cities in them, but they have more quiet countrysides hours away as well. It is in these areas that people like to go ice fishing. Getting time away from the busy city life is an incredibly relaxing experience. When people in America go ice fishing, it’s often something they do with their friends. It’s a lot of fun to relax and sit on the lake with friends, as long as you prepare well. This is part of the reason ice fishing is popular throughout the United States. If you ever want to visit any of these states in the winter, the locals will certainly have opinions on what spots are best. A few examples of lakes that have been frequently recommended online: Higgins Lake, Michigan, Lake of the Woods, Minnesota, or Lake Champlain, Vermont. Perhaps you would want to decide which part of America you want to visit and plan a fishing trip from there. When it comes to ice fishing, you can’t forget about the big country right north of the United States: Canada. Canada is huge, and a bit colder than the United States generally, so there are tons of lakes where you can go ice fishing in the winter. For example, there is Lake Simcoe in Ontario. If you want to visit Canada, I would again take the approach of choosing an area you most want to see, and choosing a fishing spot from there. Practically the whole country in the winter seems within a reasonable distance of a place to catch fish under the ice. Outdoor activities are a huge part of life in Canada, and just like in the U.S., ice fishing is a great social activity. So when it comes to North America, a large percentage of the country holds people who are fans of ice fishing. While the large crowds in cities might not care for it, out in small towns and rural areas, you are sure to meet plenty of people who love to fish during all seasons. Popular Areas for Ice Fishing In Europe It might seem like ice fishing is not as popular in Europe as in North America, but there are definitely regions where many people do it. These include Sweden, Greenland, and Finland. As you would expect, these areas have cold winters and plenty of fresh water. There are some extremely beautiful spots that should not be overlooked. In fact, there are some locations quite unique from what American ice fishing offers. Near the capital city of Finland, for example, it is actually possible to go ice fishing in the winter on the coast of the sea, and many people do this. What a unique way to catch ocean fish! In Sweden, there are regions of the Lule River that are normally only accessible by boat, but can be reached via ice in the winter, though this is technically not ice fishing! It is certainly a unique and amazing winter experience. Or you can head over to Ammassalik Island in Greenland where you’ll be able to spend some time with classic fishermen. That are using little more than a wooden pole with a string and hook at the end of it as their rod Greenland is cold enough to have some incredibly deep lakes that have a bounty of fish to aim for as you cast your rod. Ice fishing is certainly not limited to North America. Anywhere with cold winters and plenty of fresh water will offer it.

Industrial status and international status of lithium iron phosphate batteries

Abstract With the rapid development of the electric vehicle industry, power batteries have become an important element. The industrial status of lithium iron phosphate batteries can therefore be divided into two levels: one is the status of lithium batteries in the battery industry, and the other is the status of lithium iron phosphate batteries. With the rapid development of the electric vehicle industry, power batteries have become an important element. The industrial status of lithium iron phosphate batteries can therefore be divided into two levels: one is the status of lithium batteries in the battery industry, and the other is the status of lithium iron phosphate batteries in lithium batteries. On the first level, lead-acid batteries, nickel-hydrogen batteries and lithium-ion batteries are currently used as power batteries. Lead-acid batteries are strictly restricted. Because of their high pollution, they are currently restricted to the field of small electric bicycles; Ni-MH batteries have mature technology and low purchase and use costs, but they have high self-discharge rate and low specific energy, which can only be used as a transitional one. Batteries: Only lithium-ion batteries can comprehensively match electric vehicles, which have the characteristics of long cycle life and low self-discharge rate. On the second level, the difference between various lithium iron phosphate batteries is manifested in price and safety, and safety is a performance that fundamentally determines the status of different genre power lithium batteries. From the perspective of cathode materials, lithium-ion batteries can be divided into four categories: lithium cobalt oxide, lithium manganate, ternary materials, and lithium iron phosphate. Lithium cobalt oxide battery has the highest degree of industrialization and the most mature technology, but due to safety considerations, it is mainly used in the field of small batteries such as mobile phones and digital products. Among the remaining three types of lithium batteries, lithium iron phosphate batteries are favored by the industry due to their advantages in cost and cycle life, and become the development direction of China's power lithium batteries. In China, the industrialization of lithium iron phosphate batteries and their materials is basically synchronized with the international development. Looking ahead, its application fields may penetrate from the fields of electric vehicles, electric bicycles, and power tools into wind power, solar power generation devices, medical equipment, miner’s lamps and other fields. . If calculated on the basis of an annual growth rate of 10% to 20%, the current four major application areas (electric vehicles, electric bicycles, electric scooters, and electric tools) alone, the power lithium battery will have 15 billion yuan in the next 5 years Market size. If all lithium iron phosphate batteries are used for driving, by then, the lithium iron phosphate cathode material will reach a market size of 4.5 billion yuan. Although China's lithium iron phosphate is on the international starting line, the cost of Chinese products is relatively low, but it also puts itself below the critical point of industrialization in this regard, especially in patents, there is still more room for improvement.
