Alkaline zinc-manganese battery

The alkaline zinc-manganese battery comprises a battery steel shell, one end of the battery steel shell is closed and protrudes outwards to form a positive terminal, a negative current collector assembly is assembled at the other end of the battery steel shell, an isolation tube is coaxially sleeved in the battery steel shell, and one end, close to the positive terminal, of the isolation tube is closed to form an isolation tube bottom surface; a positive electrode ring is embedded in an annular cavity between the battery steel shell and the isolation pipe, and a liquid absorption layer for storing electrolyte is filled between the positive electrode terminal and the bottom surface of the isolation pipe. According to the utility model, the liquid absorption layer is filled between the positive terminal and the bottom surface of the isolation tube, so that on one hand, the liquid absorption layer fills the positive terminal, removes most residual air and prevents oxygen absorption corrosion of negative zinc pas
