In conclusion, we have demonstrated a strategy of doping light-weight boron ions into Co3O4 while recombining with graphene to stabilize the reversible oxygen redox. A nanorod-like Co3O4-B-GN2 nanocomposite was prepared by a one-pot hydrothermal method. When the obtained composite was applied as an anode material of SIBs, an excellent rate capability and remarkable cycling performance can be achieved. Co3O4-B-GN2 achieves a high reversible capacity of 424.8 mAh g−1 at a current density of

Heteroatom doping is one of the feasible strategies to improve electrode efficiency. Meanwhile, graphene helps to optimize structure and improve conductivity of the electrode. Here, we synthesized a composite of boron-doped cobalt oxide nanorods coupled with reduced graphene oxide by a one-step hydrothermal method and investigated its electrochemical performance for sodium ion storage. Because of the acti-vated boron and conductive graphene, the assembled sodium-ion battery shows excellent cycling stabil -ity with a high initial reversible capacity of 424.8 mAh g-1, which is maintained as high...
