Do you know the disadvantages of these lithium iron phosphate batteries?

Lithium iron phosphate batteries also have their shortcomings: for example, poor low-temperature function, low cathode material density, vibrating lithium iron phosphate batteries have the same volume and capacity than lithium cobalt oxide and other lithium batteries, so there is no advantage in micro batteries. When used in power lithium-ion batteries, lithium iron phosphate batteries are the same as other batteries, and they have to face the same problems as batteries. Comparison of power lithium ion batteries The most promising cathode materials for lithium batteries are modified lithium manganate (LiMn2O4), lithium iron phosphate (LiFePO4) and lithium nickel cobalt manganate (Li(Ni,Co,Mn)O2). Due to lack of resources and nickel-cobalt, high price fluctuations of cobalt and other reasons, it is generally believed that nickel-cobalt-lithium-manganese oxide ternary materials are difficult to become mainstream electric vehicle power lithium batteries, but they can be mixed with spinel lithium-manganese oxide plans. Working using carbon aluminum foil brings technological innovation and industrial progress to the lithium industry; advanced lithium battery product functions to improve the discharge multiplier. As domestic battery manufacturers are increasingly demanding battery functions, new power lithium-ion battery materials are widely recognized in China: conductive materials, conductive coated aluminum foil, and copper foil. Its advantage is: when processing battery materials, it often has a higher charge and discharge rate, good function, greater than the capacity, but the cycle stability is poor, the attenuation is more serious, etc., so it has to be discarded. This strange coating brings the energy of the battery into a new era. The conductive coating is composed of nano conductive graphite coating particles with good dispersibility. It has good electrical conductivity and is a maintenance energy absorbing layer. It can also provide good hidden protection. The coating is water-based and solvent-based, and can be used for aluminum, copper, stainless steel, aluminum and titanium bipolar plates. The application of carbon coatings on lithium batteries has brought the following advancements: 1. Reduce the internal resistance of the battery and inhibit the dynamic increase of the internal resistance during the charge and discharge cycle; 2. Significantly promote the battery together and reduce the battery cost; 3. Forward activity Material adhesion and collection liquid, making the cost of the pole-reducing film; 4. Reduce polarization, improve the multiplier and thermal effect; 5. Prevent the corrosion of the collected liquid by the electrolyte; 6. Summarize the factors and extend the battery life; 7. Coating thickness : 1 to 3 meters thick on one side. In recent years, Japan and South Korea have importantly developed lithium batteries using modified lithium manganate and nickel cobalt manganate ternary lithium as cathode materials, such as Panasonic Electric Vehicles, Hitachi, Sony, New Kobe Electric, NEC, Sanyo Electric, Samsung, LG etc. The development of the first lithium iron phosphate anode material power lithium battery, such as A123 system, price, but the first car manufacturer in plug-in hybrid vehicles and electric vehicles is the choice of manganese basic power lithium battery cathode material system , And said that the United States considers A123 as a lithium manganate material, and first adopts the cooperation methods of electric vehicle battery companies in Germany and other European countries and other countries, such as Daimler and the French Saft alliance with Japan, Germany, and the Sanyo agreement. Now, Volkswagen of Germany and Renault of France are developing and processing lithium batteries powered by their respective governments.
