Abstract:
A modular bipolar solid-state battery includes T solid-state battery modules, where T is an integer greater than one. Each of the T solid-state battery modules includes an enclosure, a first terminal arranged on a first side of the enclosure, a second terminal arranged on a second side of the enclosure opposite to the first side of the enclosure, and N solid-state battery cells arranged and interconnected in the enclosure, where N is an integer greater than one. The T solid-state battery modules are connected in at least one of series and parallel. A positive terminal of the modular bipolar solid-state battery is connected to at least one of the T solid-state battery modules. A negative terminal of the modular bipolar solid-state battery is connected to at least another one of the T solid-state battery modules.
