Abstract: A battery assembly, such as a bipolar battery assembly can be fabricated using an optical welding process. For example, a stack of biplate assemblies can be assembled including aligning the biplate assemblies using a fixture, the fixture having at least one feature sized and shaped to engage a corresponding feature in a first casing portion in the stack of biplate assemblies. The stack of biplate assemblies can be compressed. A second casing portion comprising an optically-transmissive region can be mated to the first casing portion. An optically-absorbing region of the first casing portion can be irradiated through an optically-transmissive portion of the second casing portion to form a weld structure along at least one edge of the second casing portion.

Abstract: A battery module (100) and a method of assembly of the battery module (100) is disclosed. The battery module includes cells (203) positioned in cell holders (204, 205) and a casing (101). A cell support structure (210) is integrated with a first inner surface (108a) of the casing (101) for establishing a thermal contact between the cells (203) and the first inner surface (108a). Further, the battery module (100) includes a flexible member (209) positioned between a second inner surface (102a) of the casing (101) and one of the cell holders (205) for exerting pressure on the cell holders (204, 205). A thermal interface member (207) is in contact with at least one of the cell holders (204, 205). The flexible member (209), the thermal interface member (207), and the cell support structure (203) package the cells efficiently, making the battery module mechanically stable, impact resistant, and vibration proof.
