Effects of Different Impurities on the Self-Discharge of Lithium Batteries

Leave a Comment / Pack Assembly / By

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 …

Lithium battery pre-lithium technology: cathode pre-lithium

Leave a Comment / Cell Manufacturing / By

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 …
