Battery, Battery Pack and Vehicle Including the Same

Abstract

A battery includes a cell housing, an electrode assembly positioned within the cell housing, and a current collector plate positioned within the housing and electrically coupled to both the cell housing and a second electrode of the electrode assembly. The current collector plate includes an electrode coupling portion electrically coupled to the second electrode, a peripheral portion electrically coupled to the cell housing, and at least one bridge extending between and connecting the electrode coupling portion and the peripheral portion. The bridge includes an adjustable portion configured to deform in response to an applied force, and the peripheral portion may include a rigidity reinforcing structure. The battery may be a cylindrical battery, and the electrode assembly may have a jelly-roll configuration, with the second electrode being a negative electrode. A battery pack including multiple such batteries, and a vehicle including at least one of such battery packs, is also provided.
