Patent ID: 7598000

Claim:
An anode for a lithium battery with a plurality of solid, polymeric blend, protective barrier layers, comprising: a terminal; a wire-mesh layer interposed between said terminal and a one of said plurality of barrier layers; a metal foil layer is wrapped around said wire-mesh layer and surrounded by another one of said plurality of barrier layers; said wire-mesh layer and said metal foil layer being connected to said terminal; said plurality of barrier layers being composed of a mixture of an alkali-hydroxide modified polyvinylidene fluoride, polyethylene oxide, and lithium hexafluorophosphate; said alkali-hydroxide modified polyvinylidene fluoride being in a range of between approximately 75 percent by weight and 85 percent by weight; said polyethylene oxide being in a range of between approximately 5 percent by weight and 10 percent by weight; said lithium hexafluorophosphate being in a range of between approximately 10 percent by weight and 15 percent by weight; and said plurality of barrier layers allow passage of lithium ions and oxygen ions therethrough to said metal foil layer providing a multitude of oxidation reactions and reduction reactions and prevents unwanted contact between external moisture and said metal foil layer to generate electrical energy in said lithium battery at an increased level of stability.
