What is a lithium titanate battery?

Lithium titanate battery is a lithium titanate used as a negative electrode material for lithium batteries. It can be combined with lithium manganate, ternary materials or lithium iron phosphate 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 metal lithium or lithium alloy negative electrode. Lithium titanate (LTO) material is used as a negative electrode material in a battery. Due to its own characteristics, the material and the electrolyte simply interact with each other and cause gas evolution during the charge-discharge cycle reaction. Therefore, the general lithium titanate The simple flatulence of the battery causes the battery cell to bulge, and the electrical function will also be greatly reduced, which greatly reduces the theoretical cycle life of the lithium titanate battery. The test data indicates that the general lithium titanate battery will develop flatulence after about 1500-2000 cycles, resulting in failure to operate normally. This is also an important reason for restricting the large-scale use of lithium titanate batteries. The improvement of lithium titanate (LTO) battery function is a comprehensive manifestation of the improvement of the function of a single data and the organic integration of various key data. In response to the requirements for fast charging and long service life, in addition to the negative electrode material, other key original materials of the lithium battery (including the positive electrode material, barrier, and electrolyte), combined with the experience of special engineering processes, will eventually be formed In addition, the non-flatulence lithium titanate LpTO battery product has been completed, and the mass application in electric buses has been completed. The test data shows that under the conditions of 6C charge, 6C discharge, and 100% DOD, the cycle life of the lithium titanate LpTO battery exceeds 25,000 times, and the remaining capacity exceeds 80%. The flatulence phenomenon of a battery cell is unclear. Affects its life span; and the practice and use of Chongqing fast-charging pure electric buses also indicate that after the battery is assembled, the electrical functions will also perform very well, which can ensure the daily commercial operation of pure electric buses.
