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.

Abstract: A method for producing a battery includes depositing, via sputter deposition, a coating on at least a portion of a cup shaped first housing part of the battery. The coating includes aluminium, chromium, tin, and/or an alloy having two or more of the group consisting of aluminium, chromium, and tin. The method also includes establishing an electrical connection between a current conductor of the battery and the cup-shaped first housing part of the battery and assembling the cup-shaped first housing part of the battery and a second housing part of the battery to form a housing of the battery. The housing has an interior space that includes a composite body including a positive electrode, a negative electrode, a separator, and the current conductor. The cup-shaped first housing part has a circular or oval bottom and a ring-shaped side wall.

Abstract: A process for the stabilization of the spatial alignment of the smectic layers in an FLC switching and/or display element, in which the original position of the smectic layers has been modified by electrical field treatment, which comprises alternately switching the elements during non-operation and/or when a certain temperature is exceeded which is above a predetermined temperature range which includes the operating temperature region and/or when the temperature falls below a certain temperature which is below a predetermined temperature range which includes the operating temperature region. Use of the process according to the invention ensures long-term functioning of the switching and display device, even in the case of repeated regeneration of the quasi-bookshelf geometry, and prevents worsening in the contrast and brightness and the occurrence of ghost images.
