3D plum candy-like NiCoMnO@graphene as anodes for high-performance lithium-ion batteries.

3D plum candy-like NiCoMnO microspheres have been prepared ultrasonic spraying and subsequently wrapped by graphene through electrostatic self-assembly. The as-prepared NiCoMnO powders show hollow structures and NiCoMnO@graphene exhibits excellent electrochemical performances in terms of rate performance and cycling stability, achieving a high reversible capacity of 844.6 mA h g at a current density of 2000 mA g.
