　　Introduction to the advantages and disadvantages of lithium titanate battery technology

　　Lithium titanate battery has 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 temperature range, safe, stable and green And other characteristics, so it has a very broad application prospect in the field of communication power supply. the

　　Lithium titanate battery has small size, light weight, high energy density, good sealing performance, no leakage, no memory effect, low self-discharge rate, fast charge and discharge, long cycle life, wide working temperature range, safe and stable green Environmental protection and other characteristics, so it has a very broad application prospect in the field of communication power supply.

　　When lithium titanate-ion battery is used as the 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 high temperature and low temperature environments, it also shows 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 material commonly used in traditional lithium-ion batteries, lithium titanate battery materials have almost no shrinkage or expansion in the skeleton structure during the process of charging and discharging lithium intercalation and delithiation. /The problem of electrode structure damage caused by unit cell volume strain when intercalating lithium ions.

　　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 ordinary graphite anode material is only 2C-4C.

　　Lithium titanate batteries will continue to produce gas during cycle use, causing the battery pack to bulge, especially at high temperatures, affecting the contact between the positive and negative electrodes, increasing the battery impedance, and affecting the performance of the battery. This is also one of the important obstacles that limit the widespread application of lithium titanate as a negative electrode material in batteries.

　　The process of nanonization of lithium titanate battery material particles is often difficult and requires high cost, and it is currently difficult to achieve large-scale industrial production.

　　Lithium titanate batteries have lower energy density than other types of lithium-ion power lithium batteries.
