Abstract
An object of the present disclosure is to provide a secondary battery system that functions at high voltage. The present disclosure attains the object by providing a secondary battery system comprising: a fluoride ion battery including a cathode active material layer, an anode active material layer, and an electrolyte layer formed between the cathode active material layer and the anode active material layer; and a controlling portion that controls charging and discharging of the fluoride ion battery; wherein the cathode active material layer contains a cathode active material with a crystal phase that has a Perovskite layered structure and is represented by ABOF(A comprises at least one of an alkali earth metal element and a rare earth element; B comprises at least one of Mn, Co, Ti, Cr, Fe, Cu, Zn, V, Ni, Zr, Nb, Mo, Ru, Pd, W, Re, Bi, and Sb; 'n' is 1 or 2; 'α' satisfies 0≤α≤3.5; and “x” satisfies 0≤x≤5.5); and the controlling portion controls charging so that a value of F/B in the cathode active material becomes more than 2/n that is in an over-charged state.
