Abstract
The utility model relates to battery technical field discloses a cylindrical battery and electric device. Cylindrical battery includes: casing, is provided with the pole hole on the casing, the reinforcing ring is fixedly arranged in the peripheral of pole hole, and at least part is overlapped with the peripheral of pole hole, and the pole, the pole is installed in the pole hole and is connected with the reinforcing ring. The reinforcing ring of cylindrical battery promotes the anti -deformation ability of pole hole, avoids the situation that the pressure that pole received exceeds its compression resistance. Effectively guaranteed when the heat runaway phenomenon, the pole of cylindrical battery will not fall off from the pole hole, significantly improved the use safety of cylindrical battery.
