METHOD FOR PRODUCING NEGATIVE ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a material employed in the negative electrode having a higher charge/discharge capacity, a higher charge/discharge efficiency, flatness of discharge curve, a good cycling property between charge and discharge and a higher filling density. SOLUTION: A lithium secondary battery comprises a carbon material capable of occluding and releasing lithium free and an amorphous metal compound containing metal capable of alloying with lithium.
