Abstract
A sealing assembly for sealing a through hole, and a method and device for preparing a battery cell are provided. The sealing assembly comprises: a sealing sleeve provided in the through hole and having a cavity and an opening that is in communication with the cavity; an elastic sleeve tube provided in the cavity and having a first mounting hole that extends in an axial direction of the through hole; and a central rod, which is provided in the first mounting hole and is in threaded connection with the elastic sleeve tube to enable the elastic sleeve tube to expand in a radial direction of the through hole to press the sealing sleeve and form, on an outer wall of the elastic sleeve tube, a raised portion that rivets the sealing sleeve to the through hole.
