Hydrogen absorbing electrode, nickel electrode and alkaline storage

A hydrogen absorbing electrode using a hydrogen absorbing alloy including at least one or more kinds of transition metals belonging to VIIb-group, VIII-group or Ib-group in periodic table at a specified percentage, characterized in that a surface part of the hydrogen absorbing alloy forms a rich layer including the foregoing transition metals at a percentage larger than the foregoing specified percentage. Since the rich layer exists, an activation at initial stage of charge/discharge is not required. Accordingly, this electrode can be utilized effectively for a nickel-hydride secondary battery.

Hydrogen absorbing electrode and its manufacturing method

A nickel electrode for use in an alkaline battery using a network-like alkaline-proof metal mesh having pores at the inside thereof as a core metal current collector, as well as an alkaline battery using such a nickel electrode. Inexpensive nickel electrode having high performance, great capacity can be obtained at high productivity.
