Abstract

Abstract : A novel concept of Na-ion DIBs was constructed by the vacancy rich perovskite fluoride KNCMF@rGO anode with conversion–insertion hybrid mechanisms. Abstract : A novel concept of Na-based dual-ion batteries (Na-DIBs) has been designed via a perovskite K0.79 Ni0.25 Co0.36 Mn0.39 F2.83 @reduced graphene oxide (KNCMF@rGO) hetero-nanocrystal anode, showing surface conversion and insertion hybrid mechanisms. The KNCMF@rGO//graphite (KS6) DIBs deliver superior energy/power densities and cycling stability and have a significant impact on developing energy storage devices.
