Abstract:
1. A battery including an electrochemical cell, said electrochemical cell comprising: a substrate having an inner surface and a plurality of laminated layers, wherein said plurality of laminated layers includes a high-moisture barrier layer; a first printed ink electrochemical layer covering some portion of said inner surface; a second printed ink electrochemical layer covering another portion of said inner surface; an electrolyte layer substantially covering and in contact with both said first electrochemical layer and said second electrochemical layer; a covering layer covering said electrolyte layer and bound to said substrate to form a pouch for sealing said electrolyte layer in an interior of said cell, wherein the covering layer is sealed to the substrate at at least one seal junction to form a seal area bounded by inner and outer boundaries; at least one electrode inner current collector having first and second opposing ends, wherein the first end of the current collector contacts one of the first and second electrochemical layers and the second end of the current collector is positioned within the seal junction; and at least one electrode external terminal having first and second ends, wherein the first end of the external terminal is positioned within the seal junction and the second end of the external terminal is positioned external the seal junction, wherein the internal current collector and the external terminal are discrete structures, and wherein the second end of the current collector and the first end of the external terminal terminate within the seal junction at a location distanced from the inner and outer boundaries of the seal junction.
