Abstract

Provided is a battery including a positive electrode, a negative electrode, and an electrolytic solution. The negative electrode includes a negative electrode active material layer including a negative electrode active material and a binding agent. The negative electrode active material includes a silicon-containing material. The binding agent includes a fluorine-containing resin and a polyacrylic acid metal salt. A total amount of the fluorine-containing resin and the polyacrylic acid metal salt is 10 parts by mass to 30 parts by mass on the basis of 100 parts by mass of the negative electrode active material.
