Incorporation of conductive polymer into soft carbon electrodes for lithium ion capacitors

The partial substitution of a styrene-butadiene rubber (SBR) binder with a small amount of conductive poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT-PSS) is effective for improving the kinetics for Li+ insertion into the soft carbon electrodes for lithium ion capacitors by securing additional electric conduction pathways and reducing the charge transfer resistance at high current densities without significant loss in the binding strength of the electrodes.231
