Abstract
A method for producing an energy storage cell, in particular a lithium-ion cell, whose housing is elastically deformable include introducing at least one electrode coil or electrode stack, having at least two electrodes and at least one separator arranged between the electrodes, into a housing. The method also includes introducing an electrolyte into the housing, and filling the housing with gas and generating an excess pressure in the housing, by which at least one housing wall of the housing is curved outward. The housing is sealed in a gas-tight manner such that the excess pressure in the housing and the curvature of the at least one housing wall are maintained, and such that the housing is elastically deformable in a direction perpendicular to the at least one curved housing wall.
