  • Publication number: 20220069302
    Abstract: In one or more embodiment described herein, a precursor of an active material of an electrode of a lead-acid battery may be made by a process that includes forming an active material paste and curing the active material paste to form the precursor of the active material of the electrode of the lead-acid battery. The active material paste may be made by combining at least water, an acid, a glass composition having at least 25 wt. % of a single metal oxide, and lead oxide. The metal oxide may be selected from barium oxide, lead oxide, zinc oxide, or antimony oxide.

  • Patent number: 8546006
    Abstract: A system for delivering water to a fluid electrolyte battery comprising at least one battery cell. Such a system includes a tank adapted to hold the fluid, a pump adapted to pump the fluid from the tank when the pump is turned on, at least one conduit adapted to transfer the fluid from the tank to the at least one battery cell, and a controller adapted to control the pump. The controller turns the pump on after an interval so that the fluid is transferred to the at least one battery cell.

  • Publication number: 20110027653
    Abstract: Capacitor pastes for flooded deep discharge lead-acid batteries include lead oxide, a carbon additive, and an aqueous acid. The capacitor paste contains lead and carbon in a lead to carbon mass ratio of about 5:1 to 82:1. Hybrid negative plates for flooded deep discharge lead-acid batteries can be made using such pastes in combination with traditional pastes. The hybrid negative plates include a capacitor paste on a bottom portion of the plate, and a traditional paste on the remainder of the plate. Batteries using the capacitor paste and hybrid plates exhibit improved performance over batteries with conventional plates and pastes and require less overcharge to prevent electrolyte stratification.
