Secondary battery |
摘要 |
A secondary battery is comprised of a positive electrode having a material intercalating alkali earth metal ions or lanthanoid metal ions reversibly, a negative electrode having a carbon composition intercalating those ions reversibly and an electrolyte having an organic solvent and a solute. The solute includes an alkali earth metal salt or a lanthanoid metal salt. The organic solvent is selected from a group comprising ethylene carbonate (EC), dimethyl carbonate (DMC) and vinylene carbonate (VC). The carbon composition is selected from a group comprising coke, refined coke with 99% or more purity, organic compound produced by calcined cellulose, graphite and glassy carbon. |
