摘要： A rechargeable lithium battery includes a metal-containing foam current collector, and an active mass that fills in the metal-containing foam current collector, the active mass including an active material. The electrode includes a central region and a surface region. The central region corresponds to a ±5% upper and lower area with a reference to a central thickness line of the electrode. A volume ratio of the metal and the active material in the central region is different from a volume ratio of the metal and the active material in the surface region.
