Abstract

The present disclosure relates to a battery unit and a battery module, wherein the battery unit includes an electrode assembly (1), including a main body portion (12) and a tab (11) extending from an end of the main body portion (12) along a length direction; two electrode terminals arranged at the top of the electrode assembly (1); and two current collecting members respectively electrically connecting the tabs (11) on both sides of the main body portion (12) with the respective electrode terminals on the same side; the current collecting member includes a guiding plate (51) and a supporting plate (52), the guiding plate (51) is located on one side of the main body portion (12) along the length direction and extends along a width direction, a reinforcement portion is arranged on the guiding plate (51) and is configured to reduce the deformation of one side of the guiding plate (51) towards the main body portion (12); and the supporting plate (52) is connected to an end of the guiding plate (51) along the width direction, and the tab (11) is bent relative to the length direction and is connected to the supporting plate (52). The battery unit can reduce the bending deformation of one side of the guiding plate toward the main body portion, and the electrochemical performance of the battery unit is improved.
