Bipolar battery electrical termination

Abstract

An end contact, such as for a bipolar battery assembly, can be sized and shaped to provide a low resistance electrical bond between the battery cells and a terminal. In an example, a bipolar battery assembly can include a casing, at least one bipolar current collector housed within the casing, a first monopolar current collector, a first electrolyte region defined between the bipolar current collector and the monopolar current collector, and a first electrically-conductive end contact electrically coupled to the first monopolar current collector. The first electrically-conductive end contact can include a centrally-located hub region, a plurality of planar arms extending radially outward from a centrally-located hub region, and at least one planar brace comprising a first segment extending between two planar arms amongst the plurality of planar arms. A similar end contact can be used for opposite end of the battery assembly.
