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