Poly(exTTF): A Novel Redox-Active Polymer as Active Material for Li-Organic Batteries.

The first polymer bearing exTTF units intended for the use in electrical charge storage is presented. The polymer undergoes a redox reaction involving two electrons at −0.20 V vs Fc/Fc+ and is applied as active cathode material in a Li-organic battery. The received coin cells feature a theoretical capacity of 132 mAh g−1, a cell potential of 3.5 V, and a lifetime exceeding more than 250 cycles. [ABSTRACT FROM AUTHOR]
