Abstract
The invention relates to a battery cell grouping structure and a grouping method. The battery cell grouping structure comprises a plurality of battery cell units, limiting parts and a plurality of adhesive tapes, wherein each battery cell unit comprises a plurality of battery cells which are sequentially arranged along a first direction, and the battery cell units are sequentially arranged along a second direction perpendicular to the first direction. The main planes of the battery cells are perpendicular to the second direction, and the oppositely arranged side wall surfaces of every two adjacent battery cells in the first direction are respectively a first bonding surface and a second bonding surface. The limiting piece is connected to the first bonding face and passes through the center of the first bonding face. The adhesive tape is arranged on the first bonding surface and located on the side, away from the battery cell, of the limiting piece, or the adhesive tape is arranged on the second bonding surface. And the adhesive tapes are arranged at intervals along the height direction of the battery cell. According to the battery cell grouping structure and the grouping method provided by the invention, additional supporting pieces required in grouping can be reduced, and the battery cell grouping structure has certain connection strength.
