Abstract
A connecting structure for exteriorly connecting a battery cell and a load comprises a battery cell exteriorly provided with a positive electrode terminal and a negative electrode terminal which are made of nickel-plated metal, a first connecting graphite block, and a second connecting graphite block. The battery cell is connected to a load through the first and the second connecting graphite blocks that are connected to the positive and the negative electrode terminals of the battery cell, respectively. The graphite is inexpensive and resistant to oxidation; whereas, the connecting graphite blocks and the nickel-plated metal made electrode terminals of the battery cell will melt together to form a carbon-nickel alloy after being brought into contact with one another, thus ensuring a smooth large-current discharge because of the reduction in resistance of external connection.
