Description

technical field

[0001] The present invention relates to an alkaline secondary battery positive electrode material and an alkaline secondary battery. Background technique

[0002] Alkaline secondary batteries, such as nickel-cadmium secondary batteries, nickel-zinc secondary batteries, or nickel-hydrogen secondary batteries, generally include an electrode group and an alkaline electrolyte that are sealed in a battery case. The electrode group includes a positive electrode, a negative electrode and a separator. The positive electrode includes a conductive substrate and a positive electrode material coated and / or filled on the conductive substrate, the positive electrode material containing nickel hydroxide powder and a binder as main components. The negative electrode comprises a negative electrode conductive substrate and a negative electrode material coated and / or filled on the negative electrode conductive substrate, the negative electrode material contains a main componen...
