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

Reduced graphene oxide (rGO) sheets attached with ferrocene were prepared, which showed improved lithium storage performance, especially at high current densities. Here, the ferrocene improves the specific capacity while the rGO serves as a light-weight flexible platform to anchor the ferrocene molecules to prevent them from dissolving into the aprotic electrolyte.
