Abstract
A flexible, conformal energy storage device (10) has a plurality of photovoltaic devices (40, 42, 44) formed integrally therewith. The energy source includes an anode, a cathode, and an electrolyte encapsulated between layers of oxygen and water impermeable sealing materials. The sealing materials also serve as the base upon which the photovoltaic devices are deposited. The anode and cathode of the photovoltaic devices are electrically coupled to the anode and the cathode of the energy storage device to provide a recharging current thereto.
Claims11
A flexible energy storage device comprising:
- first and second sheets of flexible polymeric sealing materials enclosing a flexible battery device comprising a battery anode and a battery cathode and having an electrolyte material disposed therebetween;
- and
- at least one flexible photovoltaic device having an anode and a cathode, and disposed on a layer of metallic reflecting material deposited on the outer surface of one of said first or second sheets of polymeric sealing materials, said battery anode being electrically coupled to said photovoltaic device anode, and said battery cathode being electrically coupled to said photovoltaic device cathode;
- and
- wherein said layer of reflecting material renders said one layer of polymeric sealing materials substantially liquid and vapor impermeable.
