The Back Cover picture shows the structure of a reduced graphene oxide (rGO)/Bi composite material synthesized through a simp
le and scalab
le procedure. The material shows both supercapacitor and battery behavior (supercapattery behavior) and achieves a specific capacity value close to its theoretical value whi
le atmospheric oxidation of metallic bismuth is inhibited by the reduced graphene oxide. More details can be found in the Full Paper by
