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.

Secondary battery and secondary battery module including the same

An electrode terminal and battery module having the same are disclosed. In one aspect, the electrode terminal includes a first sub-terminal including a plurality of guide grooves and a second sub-terminal including a plurality of guides configured to be respectively inserted into the guide grooves in a sliding manner. At least one of the guide grooves is formed in an upper surface of the first sub-terminal.

Electrode terminal and battery module having the same

A battery module includes a plurality of battery cells, each including terminal portions on a first surface thereof, the plurality of battery cells being aligned in a first direction; and a terminal connecting member configured to connect terminal portions of first and second battery cells of the plurality of battery cells that are adjacent to each other, and the terminal connecting member includes first and second contact portions spaced apart from each other to respectively come in surface contact with the terminal portions of the first and second battery cells, and a body portion connecting the first and second contact portions to each other.
