Analysis of the advantages and disadvantages of lithium titanate battery technology

Lithium titanate battery has the advantages of small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, rapid charge and discharge, long cycle life, wide working environment temperature range, safety, stability, and environmental protection And other characteristics, so it has a very broad application prospects in the field of communication power. When the lithium titanate battery is used as a negative electrode material, the potential platform is as high as 1.55V, which is more than 1V higher than the traditional graphite negative electrode material. Although some energy density is lost, it also means that the battery is safer. Since the lithium titanate battery can be used safely in both high and low temperature environments, it also reflects its important advantages of wide temperature resistance (especially low temperature resistance). At present, the safe working temperature range of Yinlong lithium titanate battery is between -50 degrees and 65 degrees. Long cycle life. Compared with the graphite materials commonly used in traditional lithium batteries, the skeleton structure of lithium titanate battery materials hardly shrinks or expands during the charging and discharging process of lithium insertion and removal. It is called a zero-strain material. The problem of damage to the electrode structure caused by the volumetric strain of the unit cell during lithium ion. The last advantage of the lithium titanate battery is its fast charge and discharge capability and high charge rate. At present, the charging rate of Yinlong lithium titanate battery is 10C or even 20C, while the battery charging rate of general graphite anode materials is only 2C-4C. Lithium titanate batteries will continue to produce gas during recycling, causing the battery pack to swell, especially at high temperatures, which affects the contact between the positive and negative electrodes, increases the battery impedance, and affects the performance of the battery. This is also one of the major obstacles restricting the widespread use of anode material lithium titanate in batteries. The process of nanometerization of lithium titanate battery material particles is often difficult and requires higher costs. At present, it is difficult to achieve large-scale industrial processing. Compared with other types of lithium-ion power lithium-ion batteries, the energy density of lithium titanate batteries is lower.
