| Zusammenfassung: | The utility model belongs to the technical field of batteries, and discloses a tab structure and a lithium battery, the tab structure comprises a tab body, the tab body comprises a fusing area, the fusing area is provided with a plurality of fusing cavities which are arranged at intervals, the plurality of fusing cavities are respectively filled with a resistance reducing piece, the resistance value of the resistance reducing piece is smaller than that of the tab body, and the resistance reducing piece is connected with the tab body. And the melting point of the resistance reducing piece is lower than that of the tab body. According to the tab structure disclosed by the utility model, the tab body can be fused in time during overload, the resistance value of the lithium battery cannot be increased, the normal performance of the lithium battery is prevented from being influenced, and the cost is relatively low; the lithium battery comprises the tab structure, has the dual advantages of overload protection and |
