The development potential of lithium iron phosphate batteries

　　The phosphate base material of lithium iron phosphate batteries is based on its ultra -long cycle life, excellent safety performance, good high temperature performance, extremely low price, and low temperature performance and multiplier discharge can reach the level of lithium drill acid. It makes it the most promising power battery material. It may become the main substitute for nickel -cadmium batteries in the next 5 years. In the next 10 years, it will become a powerful competitor for lead -acid batteries. Instead of lead -acid batteries, it becomes the main startup power supply, UPS power supply and reserve power supply, and becomes the boss of the secondary battery. On the one hand, most of the pure electric vehicle battery laboratory test data published by each enterprise, such as acceleration performance, charging time, continuous mileage, etc., must also be further verified under the actual operation of the complex external environment to further verify its reliability and production of production, as well as production. Batch quality control. On the other hand, in the production of lithium -ion batteries in my country, the diaphragm material required for lithium -ion batteries fails to make a substantial breakthrough. All rely on imports, the price is expensive, accounting for more than 30%of the cost of power battery. If large -scale production technology is achieved on this material, the cost can be greatly reduced. For China, which lacks autonomous, core car parts technology, hybrid/electric vehicle batteries and motor systems are important opportunities for relevant Chinese companies to become the world's leading suppliers. In this regard, the gap between Chinese enterprises and foreign countries is not as large as the core technology of components and components, and has cost advantages, as well as experience accumulated in electric bicycle batteries (especially lithium batteries).
