Improved Lithium Cyclability and Storage in Mesoporous SnO₂ Electronically Wired with Very Low Concentrations (≤1 %) of Reduced Graphene Oxide

On the wire: Mesoporous tin dioxide (SnO2) wired with very low amounts (≤1 %) of reduced graphene oxide (rGO) exhibits a remarkable improvement in lithium-ion battery performance over bare mesoporous or solid nanoparticles of SnO2 (see figure). Reversible lithium intercalation into SnO2/SnO over several cycles was demonstrated in addition to conventional reversible lithium storage by an alloying reaction.
