Maintenance free lead acid battery with high cycle life and a new type of grid
Abstract
Grid and active mass materials for maintenance free lead acid batteries with high cycle life are discussed. Alloys for casting and expanding materials for the grids were manufactured. With low grade Sb alloys ( 1,5 %) and PbCa alloys, energy densities of 50 Wh/kg are reached. Improved insulation, corrosion resisting alloys and inhibitors as well as suitable mass materials increase cycle life by 700. Manufacturing costs are similar to starting battery manufacturing costs. Expanded metal grids and plates of the most suitable alloys were produced.
