The utility model provides a secondary battery, it includes top cap subassembly, electric core and insulation frame. The top cap subassembly includes the top cap piece, and the top cap piece has beenseted up and has been annotated the liquid hole, the electricity core has the first ploe ear. Insulation frame sets up between top cap piece and electric core, and has to be located and annotate liquid hole below and outstanding convex closure downwards, the convex closure towards the upside undercut of top cap piece with the cavity that forms with annotate liquid hole intercommunication. The convex closure is formed with first passageway and second channel with the cavity intercommunication, and just the top surface of convex closure is located to the opening of first passageway one end, andthe side of convex closure is located to the opening of second channel one end. Because the convex closure is formed with the second channel, and the opening of second channel one end locates the sideof convex closure, consequ
