ABSTRACT:
In a lithium ion secondary battery having a positive electrode, a negative electrode, a non-aqueous electrolyte, and a container sealing the electrodes and electrolyte therein, the positive electrode is formed of a positive electrode active material which is produced by electrochemically intercalating a lithium ion into a lithium manganese-metal complex oxide in the container to give a positive electrode active material precursor comprising a lithium manganese-metal complex oxide of which lithium ion content is increased, and then releasing a lithium ion from the positive electrode active material precursor in the container, and the negative electrode is formed of a negative electrode active material which is produced by intercalating the released lithium ion into a negative electrode active material precursor of a metal oxide in the container.
