Abstract
A primary seawater battery employs a metallic sheet anode and a sheet cathode. The cathode is lead chloride including an addition of about 1 to about 10 parts by weight of lead oxide per 100 parts by weight of lead chloride. The lead oxide may be litharge, litharge containing lead, red lead or lead peroxide. Other ingredients which may be present in the cathode are carbon black for conductivity and an organic binder such as polyfluoroethylene. The battery is characterized by having a shortened rise time compared to batteries without the lead oxide additive, especially when the battery is used at low temperatures.
