BATTERY CONNECTION PIECE AND BATTERY GROUP HAVING THE BATTERY CONNECTION PIECE

摘要

A battery connection piece (100) and a battery group (10) having the battery connection piece (100). The battery connection piece (100) comprises: a first connection section (110), the first connection section (110) being made of a first conductive material; and a second connection section (120) connected to the first connection section (110), the second connection section (120) being made of a second material different from the first conductive material. By using the battery connection piece (100) according to an embodiment of the present invention to connect with a unit battery (200), not only may adjacent unit batteries (200) be connected together more reliably, but also service life and performance of a battery group (10) formed of a plurality of unit batteries (200) may be improved.
