NOVELTY - A liquid electrolyte battery electrode comprises a conductive polymer matrix (10) formed over the surface of a battery grid plate (12), and superfine particles of active material (14) coupled with the matrix.    USE - For electrical energy storage device such as high power liquid electrolyte battery e.g. lead acid battery. The lead acid battery is used for starting an automobile, providing power for electric vehicle and emergency lighting, or as storage buffer for solar electric system.    ADVANTAGE - The battery plates have a high percentage utilization of grid active material by maintaining strong skeletal structures, long cycling capability and high reaction surface area, and are deeply discharged. The polymer skeleton provides an alternative path for the transfer of electrons or charges, and hence the ionic polarization due to electric current is minimized. The corrosion of lead metal components due to the movement of oxygen ions through the lattice is reduced by the skeletal structure of conductive polymer on the grid surface. The filling and formation efficiency are improved and controlled by optimizing the microstructure of polymer skeletons. The electrochemical battery has good power production and energy capabilities during cold weather as well as hot weather, and are easily and economically fabricated. The changes in volume of active material particles that occur during charging or discharging of battery is effectively compensated by the compression or stretching of polymeric chains and hence the degradation of active material is minimized.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of producing a battery plate which involves coating the polymeric matrix with the nanoscale particles of active material.    DESCRIPTION OF DRAWING(S) - The figure shows the lead metal positive terminal and lead oxide corrosion layer that forms on the surface of metal grid plate and conductive polymer skeleton.
