Custom designed nanocrystalline Li2MSiO4/reduced graphene oxide (M = Fe, Mn) formulations as high capacity cathodes for rechargeable lithium batteries.

Abstract

Nanocrystalline Li2MSiO4 (M = Fe, Mn) particles embedded between in situ formed rGO sheets are obtained by adopting customized solvothermal synthesis. An appreciable room temperature specific capacity of 149 mA h g(-1) with 89% capacity retention and 210 mA h g(-1) with 87% retention have been exhibited by Li2FeSiO4/rGO and Li2MnSiO4/rGO composites… (More)
