A connecting structure for exteriorly connecting battery cells essentially comprises at least one connecting graphite block 30 serving as a bridge for electrical connection between two battery cells In series or parallel configuration. The connecting graphite block is directly connected to nickel-metal or nickel-plated electrode terminals 41,22 of the battery cells in a close contact manner to realize a connection with high electric conductivity among the cells without utilization of conventional welding procedures. The graphite is inexpensive and less sensitive to oxidation; whereas, the connecting graphite block and the positive as well as negative electrode terminals of the battery cells both being made of the nickel-plated metal will dissolve into each other while in mutual contact forming a carbon-nickel miscible alloy, thus ensuring a smooth large-current discharge because of the reduction in resistance of external connection. |
