Characteristics of lithium titanate battery

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 The battery is prone to flatulence, which will cause the battery core to bulge and the electrical performance will greatly decrease, 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 cause it to not be used normally. 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 the positive electrode material, separator, and electrolyte) of the lithium battery, combined with the experience of the special engineering process, 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 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%. At the same time, the flatulence phenomenon of the battery is unclear and does not affect Its longevity; 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.
