Electrode Stack And Battery System Including Electrode Stack

Abstract

An electrode stack may include: (1) a first electrode sub-stack; and a second electrode sub-stack disposed on top of the first electrode sub-stack and formed in a different shape from the first electrode sub-stack when viewed from above the second electrode sub-stack. The first electrode sub-stack and the second electrode sub-stack may be bent along a stacking direction. A battery system may include: (1) a battery unit having a bending portion in a bent shape that defines a receiving space for accommodating an electrode stack therein; and the electrode stack disposed in the receiving space.
