Detailed explanation of new lithium titanate anode materials for lithium batteries

The research and use of new anode materials have also begun to attract the attention of the industry, and new anode materials for lithium titanate batteries are a very important direction. Lithium titanate has some unparalleled advantages over other anode materials. As a negative electrode material for power lithium batteries, it has great research value and potential for commercial use. Due to the defects in the performance of traditional graphite materials, new negative electrode materials such as silicon-carbon composite materials and lithium titanate have also received extensive attention from the lithium battery industry. Lithium titanate has become a research hotspot of anode materials for new lithium batteries due to its excellent safety, ultra-long cycle performance, rapid charge and discharge, and ultra-wide high/low temperature performance, and its application prospects are also expanding. Lithium titanate battery.jpg Lithium titanate with a spinel structure is considered to be one of the most promising anode materials for lithium batteries due to its extremely high cycle life and safety characteristics. Combining highly conductive, environmentally friendly, chemically and thermally stable, and structurally diverse carbon materials with lithium titanate to form a composite negative electrode material can effectively improve the conductivity of the material while inhibiting flatulence, which is critical to the optimization of electrode material use. Compared with graphite anode, lithium titanate has a higher lithium insertion potential, which can effectively guard against the precipitation of metallic lithium and the formation of lithium dendrites. Lithium titanate and Li7Ti5O12 in the lithium-intercalated state have much higher thermodynamic stability than graphite, and are not easy to cause thermal runaway of the battery, thus having higher safety. At the same time, during the process of lithium ion insertion and extraction, the lattice parameters of lithium titanate hardly change, and the crystal structure can maintain a high degree of stability. It is a zero-strain material, so it has excellent cycle stability. In addition, lithium titanate also has excellent low temperature performance, fast charging capability, and high cost performance, so it has a good prospect of use in large-scale energy storage and other fields. Research on lithium titanate battery technology at home and abroad can be described as surging. Its industrial chain can be divided into the preparation of lithium titanate materials, the integration of lithium titanate battery processing and lithium titanate battery systems, and its use in the electric vehicle and energy storage market. There have been many domestic mass production of lithium titanate materials, such as Sichuan Xingneng New Materials Co., Ltd., Zhuhai Yinlong New Energy Co., Ltd., Huzhou Weihong Power Co., Ltd., Shenzhen Beterui New Energy Materials Co., Ltd., Hunan Shanshan New Materials Co., Ltd. and many small-scale lithium titanate battery processing manufacturers around Anhui and Shenzhen.
