▎ 摘　　要

NOVELTY - The structure has positive electrodes and negative electrodes which are electric power output terminals of battery cells respectively. A graphene connection block is electrically connected with negative electrode of battery cell. A positive electrode of battery cell is electrically connected with graphene connection block so that battery cells are connected in series. USE - Connection structure for connecting battery cells and graphene connection block of battery. ADVANTAGE - The battery cells are electrically connected in series or parallel with graphene connection block, and electrically conductive efficiency between battery cells is improved at low cost even when welding process is not carried out. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for high electrically conductive efficiency parallel connection structure.
