PROBLEM TO BE SOLVED: To provide a lithium secondary battery with easy production process, easy initial charge, high voltage, high capacity, and its manufacturing method. SOLUTION: A lithium secondary battery has a positive electrode 2, using a lithium manganese oxide as a positive active material, a negative electrode 3 using a carbon material as a negative active material, an organic electrolyte in which a lithium salt is dissolved, and a battery can 8 in which they are housed. The manufacturing method is that metallic lithium 7 is arranged in the battery can 8, the organic electrolyte is poured therein, the metallic lithium 7 and the positive electrode 2 are short-circuited, lithium equivalent to the irreversible capacity of the negative electrode 3 is introduced into the positive electrode 2 as a lithium introduction process, the initial charge is conducted between the positive electrode 2 and the negative electrode 3 to make the battery in an initial charging state. |
