SECONDARY BATTERY AND SECONDARY BATTERY MODULE INCLUDING THE SAME

摘要

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.
