Battery cell with metal shell

The utility model belongs to the technical field of batteries, and particularly discloses a metal shell battery cell which comprises a battery roll core and a conductive shell, the battery roll core comprises a positive plate and a negative plate, the conductive shell comprises an upper conductive shell and a lower conductive shell, and the upper conductive shell and the lower conductive shell are buckled to form a closed accommodating space. The battery roll core is arranged in the accommodating space, and the conductive shell is connected with the positive plate or the negative plate. The conductive shell of the battery cell with the metal shell is made of the metal material, the mechanical strength is high, the space utilization rate is high, and when the upper conductive shell and the lower conductive shell are manufactured through the stamping process, the manufacturing size deviation is small, corrosion is not likely to happen, the packaging procedure is simple, and the manufacturing efficiency is high.
