Lithium Titanate Battery Is A Lithium Ion Secondary Battery Used As A Negative Electrode Material Of Lithium Ion Battery-lithium Titanate

Lithium titanate battery is a lithium ion secondary battery used as a negative electrode material of lithium ion battery-lithium titanate, which can be combined with positive materials such as lithium manganate, ternary material or lithium iron phosphate. In addition, it can also be used as a positive electrode, with a lithium metal or lithium alloy negative electrode to form a 1.5V lithium secondary battery. Due to the high safety, high stability, long life and environmental protection of lithium titanate.

It is foreseeable that after 2 to 3 years, lithium titanate material will definitely become the anode material of a new generation of lithium ion batteries and will be widely used in new energy vehicles, electric motorcycles and those requiring high safety, high stability and long cycle Application areas. The working voltage of the lithium titanate battery is 2.4V, the maximum voltage is 3.0V, and the charging current is greater than 2C (that is, the current of twice the battery capacity value).

Lithium titanate (LTO) material is used as a negative electrode material in batteries. Due to its own characteristics, the material and electrolyte are likely to interact and produce gas evolution during the charging and discharging cycle reaction, so ordinary lithium titanate The battery is prone to bloating, which leads to the bulging of the battery core, and the electrical performance will also be greatly reduced, which greatly reduces the theoretical cycle life of the lithium titanate battery. The test data shows that the common lithium titanate battery will swell after about 1 500-22,000 cycles, resulting in the inability to use normally, which is also an important reason restricting the large-scale application of lithium titanate batteries.
