Abstract :
An innovative concept for the preparation of low carbon black loaded conductive polymer composite is described. Fine polymer powder is first coated with a carbon black layer and subsequently heat-pressed into conductive sheets. The carbon coating of the polymer particles is carried out by substrate induced coagulation (SIC) which is a relatively new and widely applicable method for coating surfaces with fine particulate materials. The introduced process results in a very low percolation level of the conductive filler and therefore enhanced mechanical properties of the electrodes comparable to properties equal to pure polymers. These novel conductive carbon polymer electrodes can be implemented in several promising advanced battery systems e.g. (i) vanadium redox or (ii) zinc-flow batteries, relevant for a wide range of stationary and traction applications
