Abstract

A lithium secondary battery which is capable of terminating its operation safely with no accompanying rapid change in appearance, no gas generation, nor pressure change when any of an overcharge, overdischarge, and abnormal temperature rise occurs in the secondary battery itself. The lithium secondary battery includes a negative electrode, which is capable of absorbing and desorbing lithium, a positive electrode, which is capable of absorbing and desorbing lithium, and a non-aqueous electrolyte, wherein the non-aqueous electrolyte is solidified by a thermal reaction at a designated temperature.
