A connecting structure for exteriorly connecting a battery cell 20 and a load 30 comprises: a battery cell 20 exteriorly provided with positive and negative electrode terminals 21, 22 made of nickel-plated metal; and first and second connecting graphite blocks 40, 50. The battery cell 20 is connected to the load 30 through the first and second connecting graphite blocks 40,50, which are respectively connected to the positive and negative electrode terminals 21, 22 of the battery cell. After being brought into contact with one another, the connecting graphite blocks 40, 50 and the nickel-plated metal electrode terminals 21, 22 of the battery cell 20 react together to form a carbon-nickel alloy thus ensuring a smooth large-current discharge due to the reduction of the external connection resistance. The graphite blocks 40, 50 are inexpensive and resistant to oxidation and may be made of pure graphite or graphite alloy (e.g. silver-carbon or copper-carbon alloy). Each of the graphite blocks 40, 50 may be interiorly provided with a wire 60 serving as a power output wire of the battery cell 20. |
