Battery

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 …
