Polyaniline (PANi) can be used as an electroactive organic cathode material in Li-cells with multiple redox states. The theoretical specific capacity of the emeraldine base (PEB) is 150 mAh g −1 this study we show how the specific capacity of PEB 90−x CB x PVDF 10 cathodes is dependent upon the mass percentage of PEB and carbon black (CB) in the potential range of 2.0–4.0 V.
