HIGH ENERGY DENSITY LITHIUM SECONDARY BATTERY

摘要

PURPOSE: A high energy density lithium secondary battery is provided to enlarge the reversible capacity of the battery after activating, and to prevent the risk of metal lithium by completely using the metal lithium during the activation process. CONSTITUTION: A high energy density lithium secondary battery comprises a negative electrode containing a material capable of lithium-alloying, and a positive electrode formed with a transition metal oxide capable of reversible lithium occlude emitting. One of the electrodes comprises a lithium layer on the surface. The lithium layer satisfies the chemical formula S
