Abstract: A battery assembly includes a first plurality of battery cells, a second plurality of battery cells, and an intermediate layer arranged in a stack. Each of the first plurality of battery cells includes a first cathode, a first cathode current collector, a first anode, a first anode current collector, and a first solid state separator, and each of the second plurality of battery cells includes a second cathode, a second cathode current collector, a second anode, a second anode current collector, and a second solid state separator. The first cathode current collectors are electrically connected in parallel to a first terminal, and the second anode current collectors are electrically connected in parallel to a second terminal. The first anode current collectors of the first plurality of battery cells are electrically connected and are electrically connected to the second cathode current collectors of the second plurality of battery cells.
