Anti-rolling type cylindrical battery cell

The utility model discloses an anti-rolling type cylindrical battery cell which comprises an inner core and a cylindrical shell located outside the inner core, the inner core is eccentrically installed in the shell, the center of the inner core deviates from the center of the shell in the radial direction, and one end of the outer wall of the inner core is close to or makes contact with the inner wall of the shell; when the cylindrical surface of the cylindrical battery cell is directly and transversely placed on a table top or other supporting planes, due to the fact that the gravity center of the cylindrical battery cell is slightly lower, the cylindrical outer surface of the battery cell makes contact with the supporting planes and is in a tumbler-like state, the cylindrical battery cell can shake in the left-right direction but does not roll, and the purpose of preventing rolling is achieved in a gravity center shifting mode. By changing the internal assembly mode, the purpose of preventing rolling can be
