A process can be used to produce a charge storage unit, especially a secondary battery, the electrodes of which contain an organic redox-active polymer, and which includes a polymeric solid electrolyte. The solid electrolyte is obtained by polymerizing from mixtures of acrylates with methacrylates in the presence of at least one ionic liquid, which imparts advantageous properties to the charge storage unit.

Solid electrolyte for organic batteries

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. These secondary batteries are especially notable for high cell voltages, and simple and scalable processing and production methods (for example by means of screen printing).

Use of certain polymers as a charge store

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).

The present invention relates to the use of a thianthrene-containing polymer as redox-active electrode material, for example as an electrode slurry, for electrical charge storage means, especially secondary batteries. It additionally also relates to the electrode material comprising the polymer, and to an electrode and an electrical charge storage means comprising the polymer.

Use of thianthrene-containing polymers as a charge store

The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus. 9,10-Bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.
