The utility model relates to the technical field of storage battery assembling, and particularly relates to a storage battery adapter electrode. The storage battery adapter electrode provided by the utility model comprises an electrode body and a welding spot module; the welding spot module is installed on the electrode body. The electrode body and the welding spot module of the adapter electrode are designed in a separated mode; when the welding spot module is abraded or has flaws, a novel welding spot module is changed without changing the whole electrode, so that the welding quality is ensured for the adapter electrode, meanwhile raw materials are saved; the production cost is lowered; the production profit is improved.
