Abstract
In a non-aqueous lithium ion secondary battery comprising a positive electrode sheet which comprises a lithium-containing transition metal oxide film, a negative electrode sheet which has a film of material capable of receiving and releasing a lithium ion, a non-aqueous electrolyte which contains a lithium salt, and a container which seals the electrodes and electrolyte therein, the lithium-containing transition metal oxide film comprises at least two layers, one of which expands during discharging while shrinks during charging, and another of which shrinks during discharging while expands during charging.
