Weld-free bipolar solid-state battery cell

A bipolar battery cell includes a stack including N current collectors, M anode electrodes, S separators, and C cathode electrodes, where N, M, S and C are integers greater than one. A first positioning member is arranged on one side of the stack and includes a first planar portion and a first slot in the first planar portion. A first one of the C current collectors extends through the first slot in the first planar portion and is folded. The first positioning member further includes a first rail portion and a second rail portion. The first rail portion and the second rail portion extend from the first planar portion. A first external tab is arranged between the first rail portion and the second rail portion and connected to the first one of the C current collectors.
