Abstract

The present invention relates to polymers and to the use thereof in the form of active electrode material or in an electrode slurry as electrical charge storage means, the electrical charge storage means especially being secondary batteries. The secondary batteries are especially notable for high cell voltages, a small drop in capacity even on undergoing several charging and discharging cycles, and simple and scalable processing and production methods (for example by means of screen printing).
