METHOD FOR FABRICATING NEGATIVE ELECTRODE FOR SECONDARY CELL

摘要

A method for readily fabricating a negative electrode for a secondary cell. The negative electrode has reciprocal characteristics including the initial activity, high−rate discharge characteristics, and corrosion resistance in good balance and is excellent in recycling. The method comprises a step of mixing negative electrode materials including a conductive material and at least two kinds of AB5 hydrogen absorbing alloys composed of substantially a single phase, having the same composition, a crystal mean length of 30 to 350 μm, and different ratios (D1/D2) of the crystal mean length (D1) to the crystal mean breadth (D2) and of molding the materials.
