Abstract
An electrochemical cell sub-assembly and a method for manufacturing same. The electrochemical cell sub-assembly includes a current collector sheet having a pair of opposite surfaces and a pair of opposite edges, each surface being coated with a respective layer of electrode material. A layer of polymer electrolyte envelopes both layers of electrode material and one of the pair of edges of the current collector sheet, thereby encapsulating the one edge of the current collector sheet white leaving exposed the other edge of the current collector sheet.
