A nickel-metal hydride accumulator for industrial applications has positive nickel hydroxide electrodes and, separated therefrom, negative metal hydride electrodes as well as an alkaline electrolyte surrounding the electrodes. An improved nickel-metal hydride accumulator that is in particular insensitive to influences of temperature has a thermal arrangement which increases the specific thermal capacity of the accumulator and is formed by an additional electrolyte volume, wherein the accumulator comprises a plastics material housing which receives the electrodes and the electrolyte and is provided with a pressure relief valve.
