▎ 摘　　要

NOVELTY - The pack has a battery cell module (2) that is provided with a heat dissipation housing with an installation cavity, the battery cell module and a graphene sheet (5). The battery cell module and the graphene sheet are installed in the installation cavity. All negative electrodes of the battery cell module face to the same direction. The graphene sheet comprises a heat conduction main portion and a heat conduction fin connected with the heat conduction main portion. All negative electrodes of the battery cell module are provided in heat conduction connection with the heat conduction main portion, and the heat conduction fin is in heat conduction connection with the heat dissipation housing. USE - Battery pack with graphene sheets for high-efficiency heat dissipation. ADVANTAGE - The heat dissipation efficiency of the battery pack is improved on the basis that the size of the battery pack is not increased. The risk of fire explosion caused by thermal runaway generated due to the fact that the heat cannot be dissipated in the battery pack is reduced. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the battery pack with graphene sheets for high-efficiency heat dissipation.
