Abstract

The present disclosure provides a battery, an energy storage device, and an energy storage system. The battery of the present disclosure includes a positive electrode sheet, a separator, and a negative electrode sheet. The separator is disposed between the positive electrode sheet and the negative electrode sheet. The separator includes a substrate film, a first adhesive layer, and a second adhesive layer. The first adhesive layer is disposed between the substrate film and the positive electrode sheet for bonding the substrate film to the positive electrode sheet, and the second adhesive layer is disposed between the substrate film and the negative electrode sheet for bonding the substrate film to the negative electrode sheet. The battery satisfies the relationship: 0.85≤(Fc·Wc)/(Fa·Wa)≤6.36; where Fc is the peel strength between the first adhesive layer and the positive electrode sheet, Wc is the coating amount per unit area of the first adhesive layer on the substrate film, Fa is the peel strength between the second adhesive layer and the negative electrode sheet, and Wa is the coating amount per unit area of the second adhesive layer on the substrate film.
