The present invention relates to a porous negative electrode for a manganese dioxide-zinc battery and a manganese dioxide-zinc battery including the same. Provided are a porous negative electrode for a manganese dioxide-zinc battery and a manganese dioxide-zinc battery including the same, wherein a fibrous layer formed to have porosity by woven carbon fibers is used so that zinc ions react during battery charging and discharging to prevent deterioration of performance by covering a negative electrode with zinc hydroxide sulfate by-product. 본 발명은 이산화망간-아연 전지용 다공성 음극 및 이를 포함하는 이산화망간-아연 전지에 관한 것으로, 탄소섬유가 직조되어 다공성을 가지도록 형성된 섬유층를 사용하므로 전지가 충방전되는 과정에서 아연 이온이 반응하여 형성된 Zinc Hydroxide Sulfate 부산물이 음극을 덮어 성능이 저하되는 것을 방지하는 이산화망간-아연 전지용 다공성 음극 및 이를 포함하는 이산화망간-아연 전지를 제공한다.
