Nanohybridization of ferrocene clusters and reduced graphene oxides with enhanced lithium storage capability

Abstract

Reduced graphene oxide (rGO) sheets attached with ferrocene were prepared via a

scalable solvothermal route. For Li ion battery electrode applications, the ferrocene

greatly improves the specific capacity while the rGO serves as light-weight flexible

platform to anchor the ferrocene molecules to prevent them from dissolving into the

aprotic electrolyte. These ferrocene/rGO nanohybrids showed excellent improvement in

lithium storage performance, especially at high current densities.
