Composition and characteristics analysis of lithium titanate battery

Lithium titanate battery composes the positive electrode: lithium iron phosphate, lithium manganate or ternary material, lithium nickel manganate. Anode: lithium titanate material. Separator: Lithium battery separator with carbon as the negative electrode. Electrolyte: Lithium battery electrolyte with carbon as the negative electrode. Battery case: Lithium battery case with carbon as the negative electrode. Characteristics of lithium titanate batteries Lithium titanate (LTO) material is used as a negative electrode material in batteries. Due to its own characteristics, the material and the electrolyte are prone to mutual use and gas evolution occurs during the charge and discharge cycle reaction. Therefore, the general lithium titanate battery is prone to flatulence, which causes the battery core to bulge, and the electrical performance will also be greatly reduced, which greatly reduces the theoretical cycle life of the lithium titanate battery. The detection data stated that the general lithium titanate battery will have flatulence after about 1500-2000 cycles, which will lead to the failure of normal use. This is also an important reason for restricting the large-scale use of lithium titanate batteries. The performance improvement of lithium titanate (LTO) battery is a comprehensive manifestation of the performance improvement of a single material and the organic integration of key materials. In response to the requirements of fast charging and long service life, in addition to the negative electrode material, other key raw materials (including positive electrode material, separator, and electrolyte) of lithium batteries, combined with the experience of special engineering processes, have finally formed a problem. The flatulence lithium titanate LpTO battery product was first realized in batches on electric buses. The detection data stated that under the conditions of 6C charging, 6C discharging, and 100% DOD, the cycle life of the lithium titanate LpTO single battery exceeds 25000 times, and the remaining capacity exceeds 80%. At the same time, the flatulence phenomenon of the battery is unclear and does not affect Its service life; and the actual use of Chongqing fast-charging pure electric buses also stated that after the batteries are assembled, the electrical performance is also quite excellent, which can ensure the daily commercial operation of pure electric buses.
