PURPOSE:To provide a lithium secondary battery excellent in charge/discharge reversibility by preventing deterioration of the reversibility of a positive pole active material at the time of discharge in a large depth, in the secondary lithium battery provided with a negative pole consisting of a lithium alloy, electrolyte of using an organic solvent and a positive pole with metal oxide serving as the positive pole active material. CONSTITUTION:A lithium alloy of containing 25 to 60mol% lithium is used for a negative pole 1, and a capacity of lithium of the negative pole 1 is set electrochemically excessive more than the capacity of a positive pole 2 to restrict the excessive lithium amount to 25mol% or less relating to the other element in the lithium alloy. |
