The utility model belongs to the technical field of lithium batteries. According to the battery, a first connecting part arranged on a battery protection plate is detachably connected with a second connecting part arranged on a steel shell battery cell body, so that the battery protection plate can be fixed on a steel shell battery cell, and then a first electric connecting piece is conducted with a battery cell positive electrode and a battery cell negative electrode; compared with the mode of conducting the battery protection plate and the steel shell battery cell body by using a laser welding mode in the existing scheme, the battery used in the utility model can omit the process of laser welding, so that the battery protection plate can be connected with the steel shell battery cell body; therefore, the phenomenon that components or flexible plates on the circuit board are damaged by high temperature generated during welding is avoided, the yield of products can be improved, the purposes of saving cost and
