| 摘要 |
An alkaline electrochemical cell is disclosed which comprises a cathode subassembly, with a metal oxide cathode and collector means for collecting current from the cathode, a zinc anode, an electrolyte in contact with the zinc anode and a nonmetallic separator between the cathode and the anode. The collector means comprises a metal plated current collector additionally plated with a layer of palladium, rhodium or platinum. In one embodiment, the metal oxide cathode is a manganese dioxide cathode and the current collector comprises a nickel plated steel clip adapted for holding the metal oxide cathode which has been plated with an additional layer of palladium, rhodium or platinum on surfaces where the collector makes contact with the cathode.
