BATTERY MODULE, TERMINAL FOR THIN BATTERY, AND TAB LEAD

摘要

PROBLEM TO BE SOLVED: To provide a battery module preventing a fitting force between a terminal and a connector from increasing, facilitating connector insertion, and having an excellent reliability in electrical connection, and a terminal for a thin battery and a tab lead for use with the battery module.

SOLUTION: A battery module is structured by laminating a plurality of thin batteries. The thin battery comprises: a battery main body in a thin plate shape formed by sealing a power generation element with a packaging material; and a tab connected to an electrode of the power generation element and drawn from an end of the packaging material to outside. In order to be connected with the thin battery to be connected to an external connector, a terminal comprises a tolerance absorption part 144 for connection to the tab, and a pin-type contact part 141 which is successively provided in the tolerance absorption part 144 for connection to the connector. A voltage detection terminal 140 comprised of a narrowed part 146 and a bending part 147 is mounted to the thin battery so that the tolerance absorption part 144 follows the deformation of the contact part when the connector is fitted.
