The present invention relates to a secondary battery (100) comprising an electrode assembly (150) and a terminal (140) that is electrically connected to the electrode assembly (150). Furthermore, the invention relates to a secondary battery module (10) comprising a plurality of secondary batteries (100, 200), wherein one terminal (130, 140, 230, 240) of one of the batteries (100, 200) is connected to one terminal (130, 140, 230, 240) of an another one of the batteries (100, 200) that is adjacent to the one of the batteries (100, 200) by a bus bar (180). In order to facilitate producability of the battery module (10) and in particular to facilitate welding of the terminal (140) to a contact element, e.g. to the bus bar (180), the invention provides that the terminal (140) is provided with a terminal plate (144), which comprises a first part (144a) and a second part (144b), wherein the first part (144a) is formed of a first material and the second part (144b) is formed of a second material that differs from the first material, and that at least one battery (100, 200) of the secondary battery (10) module, is a secondary battery (100, 200) according to the invention. |
