摘要

A secondary battery and a secondary battery assembly are provided. The secondary battery includes a bare cell, a housing, an opening and a terminal portion. The housing surrounds the bare cell. The opening is formed any one side of the housing, and includes a first opening, a second opening and a third opening formed adjacent to any one of the first and second openings. The terminal portion has at least one portion exposed to the outside of the housing through the opening so as to electrically connect between an external device and the bare cell. Accordingly, the two secondary batteries can be used by being easily connected to each other.
