Abstract
A terminal busbar includes a coupling portion that is approximately in the shape of a plate having a small thickness relative to a length and a width, and a terminal portion that is bent in a vertical direction at one end of the coupling portion. The coupling portion includes a first metal layer, a material layer and a second metal layer stacked in a sequential order along an extension direction of the terminal portion, the material layer is conductive in a normal condition, but can act as resistance when temperature rises, and the material layer includes a gas generating material that decomposes at a predetermined temperature or above to produce gas, which increases resistance. The first metal layer is integrally formed with the terminal portion, and the second metal layer provides a connect surface with an electrode lead of the battery cell.
