Abstract
Official abstract text for this publication.
A positive electrode for an alkaline secondary battery includes a positive electrode substrate and a positive electrode composite material that is provided on at least one surface of the positive electrode substrate. The positive electrode substrate contains a Ni foil or a Ni-plated steel foil. The positive electrode composite material contains a positive electrode active material. The positive electrode active material contains nickel hydroxide coated with cobalt oxyhydroxide. A weight per unit area of the positive electrode composite material with respect to the one surface of the positive electrode substrate is 0.02 g/cm2 to 0.035 g/cm2.
First claim
Opening claim text (preview).
What is claimed is: 1. A positive electrode for an alkaline secondary battery comprising: a positive electrode substrate containing a Ni foil or a Ni-plated steel foil; and a positive electrode composite material that is provided on at least one surface of the positive electrode substrate, wherein the Ni foil and the Ni-plated steel foil are not porous, the positive electrode composite material contains a positive electrode active material, the positive electrode active material contains nickel hydroxide coated with cobalt oxyhydroxide, and a weight per unit area of the positive electrode composite material with respect to the one surface of the positive electrode substrate is 0.02 g/cm 2 to 0.035 g/cm 2 . 2. The positive electrode according to claim 1 , wherein a thickness of the positive electrode substrate is 5 μm to 35 μm. 3. An alkaline secondary battery comprising: the positive electrode according to claim 1 . 4. The alkaline secondary battery according to claim 3 , further comprising a negative electrode containing a hydrogen storage alloy.
