STACKED BATTERY

A stacked battery includes a stack of cells each having an electrode body including positive electrode current collector, positive electrode, electrolyte, negative electrode, and negative electrode current collector stacked in that order, a first insulating material arranged on an opposite side of the positive electrode across a first part of the positive electrode current collector, and a second insulating material arranged on an opposite side of the negative electrode across a first part of the negative electrode current collector, the positive electrode current collector has the first part of the positive electrode current collector, a second part of the positive electrode current collector, and a third part of the positive electrode current collector, the negative electrode current collector has the first part of the negative electrode current collector, a second part of the negative electrode current collector, and a third part of the negative electrode current collector.
