Title: Management of gas pressure and electrode state of charge in alkaline batteries

Abstract

An inventive, new system that measures gas composition and pressure in the headspace of an aqueous electrolyte battery is described. The system includes a microcontroller that can use the composition and pressure information to connect a third electrode to either the anode(s) or the cathode(s) in order to balance the state of charge between the two. Results have shown that such a system can control the gas pressure inside a sealed flooded aqueous electrolyte battery to remain below 20 kPa (3 psi) and greatly extend the useable life of the battery.
