Abstract
The nonaqueous electrolyte secondary battery includes a rolled electrode assemblyE formed by rolling a positive electrode plateand a negative electrode platewith a separatorinterposed therebetween, the separatoris fixed on the outermost periphery of the rolled electrode assemblyE with an adhesive tape for fixing a roll end, an exposed portion of a negative electrode substratewithout an active material mixture layeris placed on an outermost periphery side of the negative electrode plate, a negative electrode tabis connected to the negative electrode substrateon an outermost periphery side, and the adhesive tapeis not overlapped with a roll endof the positive electrode plateand a roll endof the negative electrode substrate. Thus the battery is seldom broken even when charging and discharging are repeatedly provided at high voltage.
