A rechargeable battery assembly comprising: a first unit cell;
a second unit cell provided with a cap plate; and a connection tab mounted on a case of the first unit cell; wherein the connection tab comprises a connection tab coupling formation protruding from the first unit cell and the cap plate comprises a cap plate coupling formation protruding from the second unit cell; and the connection tab coupling formation is coupled with the cap plate coupling formation to form a mechanical and electrical connection between the two unit cells; characterised in that a first one of the said coupling formations comprises an axially projecting member provided with a circumferential extension and the circumferential extension is constrained by a second one of the said coupling formations (31 a) in such a manner as to resist axial separation of the two unit cells. |
