What is the difference between lithium titanate battery and lithium iron phosphate battery?

Lithium iron phosphate battery: refers to a lithium battery that uses lithium iron phosphate as the positive electrode material. Its characteristics are that it does not contain precious elements such as cobalt, the price of raw materials is low, and the content of phosphorus and iron are abundant in the earth, so there will be no supply problems. Its working voltage is moderate (3.2V), large capacity per unit weight (170mAh/g), high discharge power, fast charging and long cycle life, and high stability in high temperature and high heat environment. Lithium titanate battery: Lithium titanate battery is used as a negative electrode material for lithium batteries-lithium titanate, which can be combined with lithium manganate, ternary materials or lithium iron phosphate and other positive electrode materials to form a 2.4V or 1.9V lithium ion secondary battery. In addition, it can also be used as a positive electrode to form a 1.5V lithium secondary battery with metallic lithium or lithium alloy negative electrode. Due to the high safety, high stability, long life and environmental protection characteristics of lithium titanate. The difference between lithium titanate battery and lithium iron phosphate battery In the field of pure electric vehicles, most of the batteries are lithium iron phosphate batteries or ternary lithium, and the core competitiveness of Yinlong Bus, which Gree wants to acquire recently, is lithium titanate. battery. Lithium titanate battery breaks the traditional battery technology route that uses graphene as the negative electrode and changes to lithium titanate as the negative electrode material, which makes it a different kind in the eyes of peers. But it is the characteristics of lithium titanate that make the battery of this material have outstanding characteristics. The most popular domestic automobile manufacturers are ternary lithium batteries and lithium iron phosphate batteries. Lithium titanate has not yet been scaled up. In addition, the price of lithium titanate batteries is high (high processing costs and high humidity control requirements), about 9 yuan per watt-hour, and the gap between lithium iron phosphate batteries and ternary lithium batteries is about 2 yuan per watt-hour. Taking lithium iron phosphate-graphene and ternary-lithium titanate as examples, the lithium titanate battery is at a disadvantage in terms of energy density alone. From the perspective of cost, lithium titanate batteries have no advantages. Currently, Yinlong lithium titanate battery raw materials include titanium hydroxide and lithium hydroxide, and their prices are higher than graphite anode materials. According to the survey results of my country's battery network, the current cost of lithium iron phosphate batteries and ternary batteries is 1100 yuan/kwh-1200 yuan/kwh, while the cost of lithium titanate batteries is about 2-3 times that of ternary batteries.
