Abstract
In a secondary battery, a negative electrode, an electrolytic solution for negative electrode, a diaphragm, an electrolytic solution for positive electrode, and a positive electrode are disposed in order. The negative electrode includes a negative-electrode active material that has an element whose oxidation-reduction potential is more 'base' by 1.5 V or more than an oxidation-reduction potential of hydrogen, and whose volume density is larger than that of lithium metal. The diaphragm includes a solid electrolyte transmitting ions of said element alone. A secondary battery with high volumetric density is provided.
