Abstract
A crushing method for galvanic cells with high energy densities in which a mixture of used cells is placed inside an insulated container and carbon dioxide as dry ice is added to this mixture as a cooling medium. Dry ice is added to the mixture of used galvanic cells at a volumetric ration of 0.5:1 to 2:1. The mixture of used cells with dry ice is cooled down from −20° C. to −50° C. and is subsequently fed to the crushing device and subjected to crushing. A stream of used galvanic cells and a stream of dry ice granules are preferably fed simultaneously to the insulated container of the crushing device, and this mixture is forwarded to the working part of the crushing device. At the end of galvanic cell crushing, the mixture of air and gaseous carbon dioxide is returned to the insulated container.
