Abstract
Each bonded electrode of the layered-type manganese dry battery has a conductive carbon coat the surface of which contacts the adjacent positive electrode composition and is provided with protrusions of 0.05 to 0.15 mm in height, which serves to prevent the electrodes from sticking to each other even when the electrodes are punched into a prescribed shape by a press mounted with a chute and transported by pressure with the top and bottom of the electrodes facing the respectively specified sides. The protrusions formed on the surface of the coat stick into the positive electrode composition, which serves to reduce the contact resistance with the positive electrode composition, facilitating the easy maintenance of the low contact resistance. Furthermore, since the contact area with the positive electrode composition facing the coat is increased, the current collecting performance is also improved.
