Abstract

A novel concept of Na-based dual-ion batteries (Na-DIBs) has been designed via a perovskite K_0.79Ni_0.25Co_0.36Mn_0.39F_2.83@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.
