Abstract
A flexible battery structure comprises a stack of a layer of cathode active material and anode active material separated by a layer of electrolyte and held between a cathode flexible substrate and an anode flexible substrate, wherein the cathode and anode substrates have a surface area larger than the surface area of the stacked layers to form and define overlapping end portions which are hermetically sealed with a water-resistant composite material. The outer surface of the cathode and outer surface of the anode form the positive polarity and negative polarity connection leads of the battery structure. The anode and cathode substrates are flexible to accommodate applications in which the battery is subjected to bending.
