Abstract
A unique storge cell is provided in which the active mass on the positive electrode is a mixture of crystalline and an effective amount of polycrystalline lead superoxide (PbO.sub.2). These cells are characterized, inter alia, by their remarkably lower internal resistance, higher activity, better charging and discharging characteristics, lower sulphatization, higher storage capacity and greater ability to draw larger amounts of electric current in a considerably shorter period of time as compared with conventional lead-acid storage cells. Storage devices (e.g., a battery) made from such cells also exhibit superior performance characterstics as compared with storage devices made from the conventional lead-acid cells. Batteries made from such cells will be referred to as 'lead-crystal' batteries. Also, several methods are described for making the polycrystalline and crystalline lead superoxide (active mass).
