PURPOSE:To improve the water-holding capacity of a separator that is tightly arranged on the inner surface of a negative electrode zinc can and is filled positive electrode black mix inside by forming the separator while using starch as the main paste material and soaking the starch in water soluble nylon. CONSTITUTION:A separator 10 is fabricated by adding bridge formation corn starch and wheat powder to water as the main paste material, adding water soluble nylon to the paste material by 1-10wt% and mixing both, coating both sides or one side of Kraft paper that is the base material with them, and solidifying them. In addition, a zinc chloride group dry battery is formed by being tightly arranged on the inner surface of a negative electrode zinc can 12 and filling the inner part with positive electrode black mix 14 that uses manganese dioxide as the active material. As as result, the water-holding capacity of the separator 10 can be improved by the water soluble nylon with resistance to the bonding strength with water and swelling can be improved by the adhesive force and convergent force can be improved. In addition, high discharge performance can be maintained for a long period. |
