Alkalische aufladbare Batterie

摘要

The invention relates to an improvement of an alkaline storage battery and provides an alkaline storage battery excellent in high-rate discharge characteristic at low temperatures particularly by suppressing the increase of electrode resistance. The alkaline storage battery comprises a positive electrode comprising a metal oxide as the main constituent material, a negative electrode comprising a hydrogen absorbing alloy, a separator and an alkaline electrolyte wherein the negative electrode has a capacity per unit area of 10-40 mAh/cm<2>.
