(57) [Problem] To provide a hydrogen storage alloy electrode that provides a nickel-hydrogen storage battery having excellent life characteristics especially for use in a high-temperature atmosphere. SOLUTION: The hydrogen storage alloy electrode contains metal fluoride. CaF 2 , YF 3 , Al F 3 , MnF 2 , CuF 2 , FeF 3 , LaF 3 , CoF 2 , At least one selected from the group consisting of NiF 2 and NiF 2 is preferably used. The content ratio of metal fluoride is 0.1 parts by weight or more to 100 parts by weight of hydrogen storage alloy 0 parts by weight or less is appropriate. |
