1. Lithium iron phosphate battery: refers to a lithium-ion battery using lithium iron phosphate as a positive electrode material. Its characteristic is that it does not contain precious elements such as cobalt, the price of raw materials is low, and phosphorus and iron are abundant in the earth's resources, so there will be no problem of feeding. Its working voltage is moderate (3.2V), large capacity under unit weight (170mAh / g), high discharge power, fast charging, and long cycle life, high stability in high temperature, and high-temperature environment.

2. Compared with lithium iron phosphate battery, which is better? This also starts with the performance of the two batteries. As we all know, the performance of lithium batteries is mainly determined by the positive electrode, the negative electrode, the electrolyte, and the separator. The positive and negative electrode materials have an important influence on the key indicators of the battery, such as capacity, energy density, cycle life, safety, rate performance, and cost. Based on these technical characteristics of lithium titanate batteries, the industry believes that it meets the needs of new energy buses and large-scale energy storage equipment. Take the bus as an example. Generally, the mileage of a single trip does not exceed 40 kilometers. It takes at least a few minutes for each terminal to wait until the next departure. At this time, the disadvantage of the low energy density of lithium titanate batteries will not affect the use of passenger cars, but instead reflects the benefits of fast battery charging. As public transport, buses put forward higher requirements on battery safety and durability. Six new energy buses equipped with lithium titanate batteries entered the Ministry of Industry and Information Technology's "Recommended Model Catalog for New Energy Vehicle Promotion and Application" (the fourth batch in 2017), which means official recognition of the maturity of this battery technology. With the implementation of the subsidies in the later period, the selling price of lithium titanate electric buses will also decrease, and it is expected to continue to drive its sales in the future. Facing the huge new energy bus market, lithium titanate companies began to expand production.
