Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which is lost to the cell. The design of some types of lead-acid battery allow the electrolyte level to be inspected and topped up with any water that has been lost.
Improved flooded motive and deep cycle battery cells
PCT designated stageWO2026085308A3Electrolyte/reactants regenerationVent arrangementsElectrolytic agentPower battery
Methods for operating a flooded electrolyte battery cell used in motive service to prevent the loss of water. When charging the cell, water in the electrolyte decomposes electrolytically to oxygen and hydrogen gases. The method includes catalytically recombining the oxygen and hydrogen gases to water vapor, inhibiting venting of the oxygen and hydrogen gases and water vapor from the cell, providing fluid communication between the catalyst and the electrolyte for the oxygen and hydrogen gases and water vapor, and hygroscopically absorbing the water vapor into the electrolyte. Devices and battery cells for carrying out the method are also provided.
