Abstract
A cylindrical cell flattening method and apparatus are disclosed, which relate to the technical field of cell manufacturing. The cylindrical cell flattening method includes the steps of: loading a battery core onto a base; compressing an outer peripheral surface of the battery core and fixing the battery core; and applying a force to the tabs of the battery core in an axial direction thereof so as to flatten the tabs. The cylindrical cell flattening method and apparatus provided by the present application enables flattening of the tabs of the battery core without colliding with an end surface of the battery core, thus reducing the reject rate during processing.
