PROBLEM TO BE SOLVED: To provide an electrode structure in a nonaqueous-based battery such as lithium-ion battery or the like, that can respond with a proper responsiveness to radical temperature increase within the battery due to over-discharge, overcharge or the like and can effectively avoid an accident due to thermal acceleration of a battery reaction, and provide a nonaqueous-based battery containing such an electrode. SOLUTION: In the battery having a laminated structure, which comprises an electrode laminate layer, composed of a positive material or a negative material absorbing and discharging lithium and a current collector, a heat- expanding micro-capsule is included into the electrode laminate layer or along the interface between the electrode laminate layer and the current collector. |
