Lithium batteries are widely used in portable electronics, electric vehicles, and renewable energy storage systems due to their high energy density and long cycle life. However, one of the challenges associated with lithium batteries is self-discharge, the gradual loss of charge over time when the battery is not in use. Self-discharge can significantly affect the

During the first charge and discharge of the lithium battery, a solid electrolyte phase interface membrane (SEI) will be formed on the surface of the negative electrode material, permanently consuming lithium from the positive electrode, resulting in low initial Cullen efficiency (ICE) and energy density. In particular, in the process of delamination/embedded lithium of silicon-based materials, the volume of

With the rapid development of new energy vehicle technology and sales, the technical requirements for lithium batteries are also gradually increasing. At this stage, the use of new positive and negative materials and new battery structure design can improve the energy density. For example, high nickel ternary lithium positive electrode, silicon-containing negative electrode, CTB and CTC integration technology.
Recently, major OEMs are promoting super-fast charging technology, promoting 0-80% SOC takes 15 minutes or 20 minutes, so that for some large-capacity batteries, the charging rate reaches more than 4C. The battery produces a lot of heat, and the traditional liquid cold plate has been difficult to digest these heat-producing heat, and the battery temperature is
