    Abstract: The disclosure provides a battery busbar including a conductive sheet, at least two bridge portions and at least two terminal contact portions. The conductive sheet has at least one cavity portion. Each of the at least two bridge portions has a first end and a second end which are opposite to each other, and the first ends of the bridge portions are respectively connected to different sides of the at least one cavity portion. The terminal contact portions are spaced apart from each other and are respectively connected to the second ends of the bridge portions. A width direction is defined to be substantially perpendicular to a line passing through the first end and the second end of one of the at least two bridge portions; along the width direction, a width of the bridge portion is smaller than a width of the terminal contact portion.

    Abstract: Pouch-type battery cells include a first and second pouch layer, one or more electrode pairs between the two pouch layers, each pair including an anode and cathode current collector, a peripheral seal defined by a peripheral seal path and joining the two pouch layers to form a pouch encasing the one or more electrode pairs, an anode tab electrically coupled to one or more anode current collectors within the pouch and a cathode tab electrically coupled to one or more cathode current collectors within the pouch each extend outward from the peripheral seal. The anode and/or cathode tab include one or more apertures disposed along the peripheral seal path such that a portion of the peripheral seal is formed between the first and second pouch layers within the one or more apertures. The tabs of multiple battery cells can be electrically coupled via busbars to form a battery pack.

    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.
