▎ 摘　　要

NOVELTY - The secondary battery has a positive electrode and a negative electrode. The positive electrode is provided with an electrolyte containing fluorine, a current collector, a positive electrode active material and a binder. The solid electrolyte material is an oxide. The positive electrode is provided with a graphene. The negative electrode is a secondary battery containing silicon. USE - Secondary battery for vehicle (claimed). ADVANTAGE - The secondary battery has remarkably high safety can be provided. The ratio of the active material occupying the electrode volume and the electrode weight can be improved. The capacity of the secondary battery can be increased. The manufacturing cost can be reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional diagram of the state of a positive electrode portion of a secondary battery. (Drawing includes non-English language text) Positive electrode current collector (10) Negative electrode current collector (11)
