Redox Targeting of Insulating Electrode Materials: A New Approach to High-Energy-Density Batteries

A compact energy‐storage system based on redox targeting is proposed, by which insulating LiFePO4 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...

Description
Summary:A compact energy‐storage system based on redox targeting is proposed, by which insulating LiFePO4 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.
