摘要： A battery module having a battery cell assembly that is free from module banding is provided. The assembly includes an expandable battery cell having a first and second face. The assembly further includes a growth plate having a first and second face. The first face of the battery cell contacts the second face of the growth plate. The battery cell assembly further includes a first cell frame securing the growth plate on at least two sides and a second cell frame that contacts the second face of the battery cell. The first face of the growth plate includes a plurality of spacing features disposed along the first face of the growth plate that offset the first face of the growth plate from the first cell frame, which creates a cavity between the growth plate and the first cell frame. The cavity decreases when the battery cell expands.

摘要： The present disclosure relates to a coupling device for coupling two or more tab electric terminals of distinct battery cells. A pair of U-shaped jaws retains the terminals therebetween with the electrical contact surfaces facing each other. A clamping element is configured to clamp the jaws towards each other in the first direction. During the clamping, an inclined wedge surface converts the pressure in the first direction to a pressure on the terminals in a second direction, so as to establish a reliable electrical contact between the terminals, direct or with the interposition of a spacing block. Wedge surfaces can be provided laterally, for example in the arms of the jaws, or between distinct bodies forming a spacing block between the terminals.
