Patent ID: 7743785

Claim:
A compressed gas storage system comprising a tank for storing a compressed gas, a battery in physical contact with said tank, and a relief valve in communication with said tank, wherein: said tank comprises at least one curved outer surface; said relief valve is configured to be responsive to electrical current generated by said battery; said battery is configured to define an electrically active state when it reaches a temperature above a maximum safe operating temperature of said compressed gas storage system; said battery comprises a continuous multilayer structure wrapped around said tank so as to conform to and cover said curved outer surface of said tank, said continuous multilayer structure comprising an anode layer in direct physical contact with said tank, a cathode layer disposed over said anode layer, and a thermally activated electrolyte layer separating said anode layer and said cathode layer; and said electrically active state of said battery is characterized by the generation of sufficient electrical current to open said relief valve, permitting gas to escape from said tank.
