NOVELTY - A zinc-manganese dioxide secondary battery comprises a separator, a positive electrode comprising manganese dioxide arranged on one side of the separator, a negative electrode containing zinc arranged on the other side of the separator, and a diffusion barrier layer arranged between the separator and the positive electrode. USE - Zinc-manganese dioxide secondary battery. ADVANTAGE - The zinc-manganese dioxide secondary battery prevents capacity reduction due to loss of active material due to the elution of manganese ions.
