CELL |
| 摘要 |
The present invention provides a cell that has a high theoretical voltage and theoretical capacity, and can be discharged and recharged multiple times. The cell includes a cathode, an anode, and an electrolyte, wherein the cathode contains a cathode active material containing an alkali metal compound represented by the formula (1):;AxOy (1);(wherein A is an alkali metal atom, x is 0.5 to 2.5, and y is 0.5 to 2.5), the anode contains an anode active material containing at least one selected from the group consisting of an alkali metal, tin, titanium, boron, nitrogen, silicon, and carbon, and the cathode, the anode, and the electrolyte are hermetically sealed in the cell. |

1. A secondary cell comprising:
a cathode; an anode; and an electrolyte, wherein the cathode comprises a cathode active material containing an alkali metal compound represented by the formula (1):
AxOy (1)wherein A is an alkali metal atom, x is 0.5 to 2.5, and y is 0.5 to 2.5,
reactions at the cathode include one represented by the following formula:
A2O2+2A++2e−2A2Owherein A is an alkali metal atom,
the anode comprises an anode active material containing at least one selected from the group consisting of an alkali metal, tin, titanium, boron, nitrogen, silicon, and carbon, and the cathode, the anode, and the electrolyte are hermetically sealed in the secondary cell. |
