▎ 摘　　要

NOVELTY - The secondary battery has a positive electrode (573) and a negative electrode (570), in which the negative electrode has a fluorine-containing solvent, a current collector (574), a negative electrode active material (572), and a graphene. The negative electrode includes a solid electrolyte material, in which the solid electrolyte material is an oxide. The negative electrode active material is silicon, tin, gallium, aluminum, germanium, lead, antimony, bismuth, silver, and zinc, and a material has elements selected from zinc and indium. USE - Secondary batter used for vehicle. ADVANTAGE - Provides a negative electrode that does not easily deteriorate. Provides a secondary battery that does not easily deteriorate, and provides a highly safe secondary battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a vehicle. DESCRIPTION OF DRAWING(S) - The drawing shows the cross-sectional view of the secondary battery, and the negative electrode. Negative electrode (570) Negative electrode active material (572) Positive electrode (573) Current collector (574)
