Solid state electrochemical cell and current collector therefor

摘要

A solid state laminar electrochemical cell having an alkali metal anode layer; a solid ionically conductive electrolyte layer; a cathode composition layer; and a current collector is described. The electrolyte layer is interposed between the alkali metal anode layer and the cathode layer. The cathode layer is interposed between the electrolyte layer and the current collector. The surface of the current collector which contacts the cathode layer is microroughened to enable the cathode layer to tightly adhere to the current collector.
