A compact energy‐storage system based on redox targeting is proposed, by which insulating LiFePO 4 particles can be reversibly charged and discharged by redox shuttle molecules ( S ; see scheme) even in the absence of conducting additives. The energy density of such batteries is expected to be greatly improved.
