Abstract
Abstract Improved polymer batteries and improved methods of manufacturing such polymer batteries are provided. One improved method of manufacture involves the formation of a laminated array structure that includes a number of individual battery cells. After formation of the laminated array the individual batteries are singulated from the array by cutting, shearing or stamping. Other manufacturing improvements include the use of a printing process (e.g. stenciling) to form the cathodes, the use of permanent mask layers to contain and insulate the cathodes and anodes, and the use of a molten lithium deposition process for forming the anodes.
