Abstract
A sealed rechargeable nickel-zinc or silver-zinc electrochemical cell including two compartments, one having a zinc electrode and a first hydrogen electrode and the other having a nickel or silver electrode and a second hydrogen electrode electrically connected to the first hydrogen electrode. The two compartments share a common gas space. During discharge the cell acts as a conventional nickel-zinc or silver-zinc electrochemical cell. During charging the gases evolved are immediately internally consumed, allowing the entire cell to be sealed. Furthermore, when the cell is fully charged there is a noticeable voltage jump which serves as a clear indication that the cell is fully charged and helps prevent overcharging and its detrimental effects.
