Abstract
A method for producing a battery includes providing a cup-shaped first housing part having a bottom and a side wall, the bottom and the side wall each having an inside and an outside. The method further includes covering the inside of the bottom of the first housing part with an electrically conductive covering, electrically connecting the electrically conductive covering to the bottom of the first housing part by welding, electrically connecting an electric conductor to the electrically conductive covering by welding, and assembling the first housing part and a second housing part to form a housing of the battery, the housing enclosing an interior space that includes a composite body therein. The composite body includes a positive electrode, a negative electrode, a separator, and the electric conductor. The inside of the bottom and the inside of the side wall of the first housing part face the interior space.
