Abstract

Absorption mat lead-acid batteries poorly dissipate heat from the internal components of the battery due to the air gap which exists between the plates and the inner wall of the container. Improved thermal management of the battery is achieved by filling the air gap, an insulating gap, with a thermally conductive gel, such as a gel formed of fumed silica and sulfuric acid electrolyte.
