Abstract
A storage battery cell (38) having a positive electrode (20) and a negative electrode (22) which are immersed in a liquid electrolyte (14). The negative electrode (22) is partially exposed to a gas space (18) within the battery cell housing (12). A pressure relief valve (34) allows excess gas to escape the battery cell (38) while preventing air from outside the cell from entering the oxygen in the gas space (18). Exposing a section of the negative plate (22) to oxygen in the gas space (18) reduces water consumption of the cell (38) and extends the maintenance-free life of the battery.
Claims
AMENDED CLAIMS
[received by the International Bureau on 28 April 1997 (28.04.97); new claims 21 - 25 added; remaining claims unchanged (1 page)]
20. A battery in accordance with claim 16 further comprising a separator between said negative and positive plates, and further comprising a catalyst in communication with said gas space.
21. A method of storing electricity, comprising the steps of: electrically charging a battery having a sealed housing; a liquid electrolyte within said sealed housing; a positive electrode immersed in said electrolyte; a negative electrode immersed in said electrolyte; a pressure relief valve disposed in said battery to allow gas to escape said sealed housing while preventing oxygen from outside the housing from entering therein; collecting oxygen created within said housing; and exposing a section of the negative electrode to the collected oxygen.
22. A method as defined in claim 21 wherein said oxygen collects in a gas space above a liquid level of said electrolyte, and wherein said negative electrode is exposed to the collected oxygen by being partially exposed above said liquid level into said gas space.
23. A method as defined in claim 21 wherein said electrode comprises a plate.
24. A method as defined in claim 23 wherein the electrolyte comprises sulfuric acid.
25. A method as defined in claim 21 further comprising the step of exposing hydrogen and the oxygen within said housing to a catalyst to form water.
