NEGATIVE-ELECTRODE COMPOSITION FOR ALKALINE SECONDARY BATTERIES, AND ALKALINE SECONDARY BATTERY NEGATIVE ELECTRODE

An alkaline secondary battery negative electrode and a composition forming the negative electrode, containing an active material, a binder resin, and an electrically conductive agent containing an electrically conductive carbon material. When a value of D50 is defined to be an average particle size X and a value of D20 is defined to be a particle size Y in a cumulative particle size distribution obtained by measuring the active material using a laser diffractometry particle size distribution meter, the average particle size X is 10 μm or less, and the particle size Y is in the range of 30% to 70% of the average particle size X.
