  • Powder of electrolytic manganese dioxide and process for producing the same
    Patent number: 6630065
    Abstract: A powder of electrolytic manganese dioxide and a process for producing the same are disclosed. The powder has a maximum particle diameter of 100 &mgr;m or smaller, a content of 1 &mgr;m and smaller particles of lower than 15% by number, and a median diameter of from 20 to 60 &mgr;m, and which has a potential of 270 mV or higher in terms of the potential of a suspension of the powder in 40% aqueous KOH solution as measured using a mercury/mercury oxide reference electrode as a base.

  • Secondary battery
    Patent number: 4968569
    Abstract: A secondary battery which comprises a positive-electrode material, an electrolyte solution, a negative-electrode material comprising zinc, and a negative-electrode substrate made of lead or a lead alloy. In a modification, the negative-electrode substrate is made of an electro-conductive material, with the surface thereof being coated with lead or a lead alloy. The battery is free from dendrite short-circuit and has an improved cycle life.
