Abstract

According to an embodiment, a secondary battery is provided. The secondary battery includes a positive electrode, a negative electrode, separator, and an aqueous electrolyte. The separator is located at least between the positive electrode and the negative electrode. The separator includes a composite film. The composite film includes a mixture of a polymeric material and ion conductive solid electrolyte particles having alkali metal ions conductivity. The polymeric material includes a polymer comprising a monomer unit. The monomer unit is a hydrocarbon with a functional group including at least one element selected from the group consisting of oxygen (O), sulfur (S), nitrogen (N), and fluorine (F). A ratio of the polymer in the polymeric material is not less than 70 mol %.
