Abstract
Thin Film Batteries are made of battery layers. Each battery layer has a substrate with one or more battery structures on the substrate surface. The battery structures have a first electrode connection and a second electrode, a first electrode (e.g. a cathode or anode) is electrically connected to the first electrode connection and a second electrode (e.g. an anode or cathode) is electrically connected to the second electrode connection. An electrolyte is at least partial disposed between and electrically connected to the first and second electrodes. A first edge connection on one of the substrate edges is physically and electrically connected to the first electrode connection. A second edge connection on one of the substrate edges is physically and electrically connected to the second electrode connection. An electrically insulating lamination is disposed on the substrate and covers the components except for the first and second edge connections, connected to respective battery electrodes. A first stack external connection electrical connects two or more of the first edge connections and a second stack external connection electrical connects two or more of the second edge connections. A first and second battery pole are connected to the respective first and second stack external connections. The TFBs are hermetically sealed.
