| 摘要 |
A solid vanadium rechargeable battery, including; a first vanadium compound containing vanadium, whose oxidation number changes between 2 and 3 due to oxidation and reduction reactions, or solid vanadium salt or complex salt including such vanadium, and a surface that becomes a negative electrode; a second vanadium compound containing vanadium, whose oxidation number changes between 5 and 4 due to reduction and oxidation reactions, or solid vanadium salt or complex salt including such vanadium, and a surface that becomes a positive electrode; and a separator sandwiched between the first and the second vanadium compounds for selectively allowing ions to pass through, is provided. |
