Electrical storage device and method for manufacturing the same

摘要

An electrical storage unit that includes a positive electrode, which includes a positive-electrode collector electrode and a positive-electrode active material layer on the positive-electrode collector electrode, a negative electrode, which includes a negative-electrode collector electrode and a negative-electrode active material layer on the negative-electrode collector electrode, the negative-electrode active material layer facing the positive-electrode active material layer, and a first insulating layer bonded to the positive electrode and the negative electrode and separating the positive electrode from the negative electrode. The first insulating layer is bonded to part of a surface of the positive electrode and part of a surface of the negative electrode and includes a communication path for connecting the outside of the electrical storage unit to the inside of the electrical storage unit.
