Abstract

The present invention relates to a bimetallic busbar (1) for interconnecting the positive (10) and negative (11) terminals of cells (9) in a battery assembly (8) comprising. In an embodiment, the busbar comprises a conducting base member, configured in the form of an intermediate portion (2), at least two spaced apart fingers, a first finger (3) and a second finger (4), supported in an upright manner on said base member (3). The first finger (3) has an abutting surface (5) for establishing face contact with a contacting surface of the positive terminal (10) of one of the cells (9) and the second finger (4) has an abutting surface (5') for establishing face contact with a contacting surface of the negative terminal (11) of another cell of the battery module. The abutting surface of each of the fingers is aligned in-line with the plane of its corresponding cell terminal, and the metallic property of each of the abutting surfaces is essentially the same as its corresponding cell terminal's contacting surface.
