The MnO2/Li cylindrical cell has been developed using a lithium-aluminum alloy negative electrode and an electrolytic manganese dioxide positive electrode with high specific surface area. The cell capacity at −20°C with the lithium-aluminum negative electrode has retained 90% after stored for 40 days at 60°C. The high retention was explained by no formation of LiOH on the lithium-aluminum alloy surface in storage, though the formation of LiOH was observed in the pure lithium negative electrode. The cell voltage on pulse discharge at −20°C was improved by using the electrolytic manganese dioxide with high specific surface area, and the cell capacity at −20°C increased about 38% compared with the conventional electrolytic manganese dioxide.
