Abstract

Electrode materials and binder materials are used for lithium cells, such as lithium ion cells. To optimize the specific power [W/kg] or power density [W/l] and specific energy [Wh/kg] or energy density [Wh/l], at least one electrically conducting, polymeric binder is used which is selected from the group consisting of polyphenylenes, polypyrroles, polyanilines, polythiophenes and lithium salts thereof. The at least one electrically conducting, polymeric binder is used in a lithium cell.
