| 摘要 |
A cathode for an electrochemical cell is disclosed, and a cell including it, together with an active cathode current collector for use in an electrochemical cell and methods of forming such a cathode. The cathode in its discharged state comprises an intermediate refractory hard metal compound of at least one metal selected from: chromium, iron, manganese, cobalt and nickel with at least one non-metal selected from: carbon, boron, nitrogen, silicon and phosphorous. The cathode is halogenated in its charged state. To form the cathode, the intermediate refractory hard metal is formed and then activated to make it capable of reacting electrochemically with halide ions in use in a cell. The active cathode current collector comprises a core of electroconductive material protected by said intermediate refractory hard metal compound as a surface layer thereon, activated to react electrochemically with halide ions in a cell. |
