文摘
- •
MnCo2O4/graphene was synthesized and coated on Ni Foam via a facile approach.
- •
High density of MnCo2O4 nanoparticles of ~5–10 nm are dispersed on graphene.
- •
The binder-free electrode delivers a capacity of 868 mAh/g after 80 cycles.
- •
The prominent performance is associated with synergistic effects of Ni -graphene.
