Title: Use of hydrogen-absorbing electrode in alkaline battery. [For protection against electrochemical damage due to battery reversal]

Patent ·
OSTI ID:7343557

Alkaline batteries are described in which a special electrode is incorporated in the positive electrode in order to give added protection against electrochemical damage due to battery reversal. This special electrode contains a hydrogen-absorbing material which also acts as a hydrogen electrode for the conversion of hydrogen ions into elemental hydrogen. Such alkaline batteries are particularly well protected against hydrogen overpressure due to battery reversal with only a small penalty in energy density. Particularly suitable for this application is the use of a hydrogen-absorbing material with nominal formula LnM/sub 5/, in which Ln represents a lanthanide metal and M is either cobalt or nickel. 3 figures.
