Abstrakt: A novel concept of Na-based dual-ion batteries (Na-DIBs) has been designed via a perovskite K0.79Ni0.25Co0.36Mn0.39F2.83@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. [ABSTRACT FROM AUTHOR]
