Abstract
Abstract The present invention relates to a deferred actuated battery assembly system comprised of a plurality of bipolar electrodes disposed between an inert cathode current collector acting as a hydrogen electrode and an anode plate formed of a material selected from the group consisting of aluminum, magnesium, aluminum alloys, magnesium alloys and mixtures thereof and configured for the flow of hydroxide-based alkaline electrolyte solutions selected from the group consisting of potassium hydroxide, sodium hydroxide and mixtures thereof.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A battery assembly system, which comprises: a battery assembly comprised of an anode plate formed of a material selected from the group consisting of aluminum, magnesium, aluminum alloys, magnesium alloys and mixtures thereof; an inert cathode current collector plate functioning as a hydrogen electrode and a plurality of space-apart bipolar electrodes disposed between and spaced-apart from said anode plate and said inert cathode plates, each of said bipolar electrodes including an anode layer formed of a material selected from aluminum, magnesium, aluminum alloys, magnesium alloys and mixtures thereof and an inert cathode current collector layer functioning as a hydrogen electrode and laminated to said anode layer; storage means for a hydroxide-based alkaline electrolyte solution selected from the group consisting of potassium hydroxide, sodium hydroxide and mixtures thereof; and means for introducing said hydroxide-based alkaline electrolyte into said battery assembly.
Claim 2
Dependent Claim
139 words
A battery assembly system, which comprises: a battery assembly comprised of an anode plate formed of a material selected from the group consisting of aluminum, magnesium, aluminum alloys, magnesium alloys and mixtures thereof; an inert cathode current collector plate functioning as a hydrogen electrode and a plurality of space-apart bipolar electrodes disposed between and spaced-apart from said anode plate and said inert cathode plates, each of said bipolar electrodes including an anode layer formed of a material selected from aluminum, magnesium, aluminum alloys, magnesium alloys and mixtures thereof and an inert cathode current collector layer functioning as a hydrogen electrode and laminated to said anode layer; storage means for a hydroxide-based alkaline electrolyte solution selected from the group consisting of potassium hydroxide, sodium hydroxide and mixtures thereof; and means for introducing said hydroxide-based alkaline electrolyte into said battery assembly.
Claim 3
Dependent Claim
21 words
The battery assembly system as defined in claim 1 wherein gaseous hydrogen is withdrawn as a by-product from said battery assembly.
Claim 4
Dependent Claim
26 words
The battery assembly system as defined in claim 1 and further including means for recirculating said hydroxide-based alkaline between said storage tank and said battery assembly.
