ABSTRACT:
A rechargeable alkaline manganese cell provided, having improved capacity and improved energy density. The cell is anode limited, and each of the anode and cathode is physically dimensioned so that the anode has a capacity in the range of from about 55% to 100% of the theoretical one electron capacity of the cathode. The gravimetric energy density of the cell exceeds 70 Wh/kg, and the volumetric energy density of the cell exceeds 200 Wh/liter. Each of the anode and cathode may comprise additional additives. For example, the cathode may include additional hydrophobic materials and a porous additive such as carbon black so as to improve gas transport of hydrogen gas into the cathode where it is oxidized; and the anode may comprise hydrogen gassing inhibitors as well as hydrogen gas recombing agents.
