The cycle times of lithium titanate batteries are three or four times that of ordinary lithium batteries. Generally, traditional ternary lithium-ion batteries, lithium iron phosphate batteries, etc. will have a significant reduction in capacity and life after repeated charge and discharge cycles, which first affects normal use. Time, but also increase the cost of battery replacement, to know that replacing a lithium battery pack is very expensive, accounting for half of the product price. This situation is not conducive to the sustainable development of the new energy vehicle industry.
On the contrary, the lithium titanate battery solves these problems well. During charging and discharging of lithium titanate batteries, the intercalation and deintercalation of lithium ions will not cause the crystal structure of lithium titanate to change, so it has almost no effect on the structure of lithium titanate materials. For this reason, lithium titanate is also called "zero strain material". Lithium titanate batteries are very advantageous compared to current lithium iron phosphate batteries that use "slow charge up to 5 years and fast charge up to 2 years." According to the test data, the average battery cycle life is 3,000 times, and the lithium titanate battery can fully charge and discharge more than 30,000 times. After 10 years of use as a power battery, it may be reused as an energy storage battery. 20 years. This also means that the lithium titanate battery can achieve the same life cycle as the vehicle, the user does not need to replace the battery in actual use, and almost does not increase the later cost.
