LITHIUM SECONDARY BATTERY

摘要

PURPOSE:To provide a negative electrode for lithium secondary battery with excellent charging/discharging characteristic and mass-productivity by using Al-Mn-In alloy as a negative electrode alloy carrier which lithium is occluded in and discharged from. CONSTITUTION:Al is used as main material, to which Mn and In are added to form an alloy carrier, and Li is occluded therein to accomplish a lithium alloy negative electrode. Contents of Mn and In are 0.5-3wt.% and 0.5-5wt.% of the total amount of negative electrode alloy carrier, respectively.
