Claim 0:
1. A battery unit, comprising:
an electrode assembly, comprising a main body portion and tabs extending from ends of the main body portion along a length direction of the electrode assembly;
two electrode terminals arranged at a top of the electrode assembly; and
two current collecting members electrically connecting the tabs on the ends of the main body portion with the two electrode terminals, respectively;
wherein each of the two current collecting members comprises a guiding plate and a supporting plate,
wherein the guiding plate is located on one end of the ends of the main body portion along the length direction and extends along a width direction of the electrode assembly,
wherein a reinforcement portion is arranged on the guiding plate and is configured to reduce the deformation of the guiding plate towards the main body portion,
wherein the supporting plate is connected to an end of the guiding plate along the width direction, and the tabs on the one end are attached with an outer side of the supporting plate and bent together with the supporting plate relative to the length direction,
wherein the reinforcement portion comprises a plurality of ribs including a first rib and a second rib,
wherein each of the plurality of ribs protrudes out of the guiding plate and away from the main body portion to reduce the deformation of the guiding plate towards the main body portion when the supporting plate is being bent,
wherein the first rib is configured to support the supporting plate and allow the supporting plate to be substantially parallel to the guiding plate when being bent, and the first rib has a first protruding height h1 relative to the guiding plate, and
wherein the second rib is configured to prevent the supporting plate from overlapping with the second rib when the supporting plate is being bent, the second rib has a second protruding height h2 relative to the guiding plate, and the second protruding height h2 is greater than the first protruding height h1, and

wherein the tabs on the one end comprise a first tab segment and a second tab segment, two ends of the first tab segment respectively being connected to the main body portion and the second tab segment, the second tab segment being connected to the supporting plate, and the supporting plate being located between the second tab segment and the reinforcement portion along the length direction.
