A busbar module connects a first cell and a second cell adjacent to the first cell, arranged in a first direction and each having first and second electrode terminals spaced apart in a second direction normal to the first direction. The busbar module includes a busbar that electrically connects a first electrode terminal of the first cell and a second electrode terminal of the second cell to each other, and an insulating portion that accommodates the busbar. The busbar includes a first recessed mounting portion, the first recessed mounting portion and a protruding shape of the first electrode terminal having interfitting shapes and a second recessed mounting portion, the second recessed mounting portion and a protruding shape of the second electrode terminal having interfitting shapes, the first and second mounting portions, being slideably coupleable with the first and second electrode terminals.

Busbar module

A secondary battery includes an electrode assembly, a battery case, and a cap assembly. The electrode assembly may include a first electrode plate, a second electrode plate, and a separator. The battery case may accommodate the electrode assembly, which may be inserted into the battery case through an opening provided on one side of the battery case. The cap assembly may include a cap plate coupled to the side of the battery case including the opening and sealing up the battery case, and first and second terminals spaced on the cap plate. The first and second terminals may each include first and second terminal plates including protrusions that protrude away from the electrode assembly, and first and second terminal connection members on the first and second terminal plates and including grooves that can be combined with the corresponding protrusions.
