Abstract
Provided is an electrode for a battery which effectively suppress a short circuit between a positive electrode and a negative electrode at high temperature of the battery. The electrode includes a current collector, an active material layerformed on at least one side of the current collectorand an insulating layerformed on the surface of the active material layer. The electrode was formed so that peeling occurs between the current collectorand the active material layerand the peeling strength was 10 mN/mm or more when a 90° peeling test was performed at a peeling rate of 100/min.
