No carbon added : Using the intrinsic oxidative power of LiFePO 4 /FePO 4 combined with the reinsertion of lithium ions, the formation of the conducting polymer poly(3,4‐ethylenedioxythiophene) (PEDOT) at the solid surface is demonstrated (see picture). The resulting composites have very promising electrochemical properties in rechargeable lithium batteries; in particular, they allow for the elimination of carbon additives.
