    Abstract: Metal hydride batteries comprising an electrolyte composition which comprises an aqueous solution comprising one or more compounds selected from the group consisting of metal hydroxides, metal oxide/hydroxides and ammonium hydroxides where when the electrolyte composition comprises KOH, the composition also comprises a further compound selected from the group consisting of metal hydroxides, metal oxide/hydroxides and ammonium hydroxides, exhibit reduced degradation of the anode material during operation. Anode materials advantageously exhibit ≤ 95% of the degradation of the same anode material in the same battery when replacing the electrolyte composition with 6M aqueous KOH and exhibit conductivity of ≥ 50% of that of 6M aqueous KOH. Anode materials are for example ABx high capacity hydrogen storage alloys comprising Mg where x is from about 0.5 to about 5 and which has a discharge capacity of ≥ 400 mAh/g.
