The price of lithium batteries has always been the focus of consumer concern, especially for expensive projects such as Tesla electric cars and photovoltaic energy storage systems.

　　Lithium iron phosphate materials are far cheaper than ternary materials, but why are lithium iron phosphate batteries more expensive than ternary batteries?

　　1. The lithium iron phosphate battery has consistency efficiency problems in the coating process

　　The uniformity of the coating process is strictly controlled during the production of lithium batteries.

　　Due to the density and particle size of the lithium iron phosphate material, it is difficult to achieve the same consistent yield as the ternary material, which will push up the cost of this link.

　　2. Difficult to dry lithium iron phosphate battery

　　Because the lithium iron phosphate battery pack has a large surface area and a large amount of binder, it is difficult to dry after coating and requires a longer heat preservation and drying time, which undoubtedly increases labor hours and power costs.

　　3. The flexibility of the pole piece of lithium iron phosphate is poor

　　When the pole piece of lithium iron phosphate is processed, it is generally hard, easy to drop powder, break, and cause short-circuit and other defects. The defect rate is far greater than the process of using ternary materials.

　　4. Poor bonding performance of lithium iron phosphate battery

　　The particles of lithium iron phosphate materials are small, so more binders are needed. However, if the binder is used too much, the energy density will be reduced if the content of the active material is reduced, which is a difficult choice. The increase in the amount of binder used leads to an increase in the cost of lithium iron phosphate batteries.

　　The above is a series of problems that may be encountered in the production and processing of lithium iron phosphate materials in lithium battery packs. These problems have caused the production cost of lithium iron phosphate to be higher than that of ternary lithium batteries.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect substitute for lead-acid batteries and are the first choice in the energy storage industry.
