A bus bar module includes an output terminal that has a male screw, a tab for preventing a wiring terminal from being rotated subserviently, and a terminal connecting portion with which a terminal of a battery element in a battery pack is connected, and a module main body from which a portion of a terminal installation portion to which the output terminal is installed is protruded. The terminal installation portion has an engagement tab that elastically deforms during an installation of the output terminal and recovers after the installation to engage the output terminal with the terminal installation portion. The tab is located so as to prevent a tool from contacting with the engagement tab when connecting the terminal connecting portion with the terminal of the battery element. According to the module, the output terminal can be prevented from dropping off even during its installation to the battery pack.

The present disclosure discloses a secondary battery and a manufacturing method thereof. According to the present disclosure, the influence of heat generated at a welding spot between an electrode tab and an electrode lead on the performance of a secondary battery may be minimized. Accordingly, in the design of a large capacity secondary battery, the battery performance may be close to an ideal condition.

Battery electrodes are provided that can include a conductive core supported by a polymeric frame. Methods for manufacturing battery electrodes are provided that can include: providing a sheet of conductive material; and framing the sheet of conductive material with a polymeric material. Batteries are provided that can include a plurality of electrodes, with individual ones of the electrodes comprising a conductive core supported by a polymeric frame.

Provided is a battery pack in which a terminal stand having electrode terminals of battery modules inserted and connected thereinto is formed at one side of a sub plate in which the battery modules are seated, such that the battery modules are easily electrically connected to each other and are attachable and detachable.
