Abstract
A battery includes a positive electrode; a negative electrode; a separator; and an intermediate layer. The intermediate layer is provided between the positive electrode and the separator and includes one or both of a fluororesin and a particle. The positive electrode has a positive electrode active material layer including a fluorine-based binder having a melting point of 166° C. or less, and a content of the fluorine-based binder in the positive electrode active material layer is from 0.5% by mass to 2.8% by mass.
