Description
Summary:NiO/C-Ni composite is prepared via a facile hydrothermal pretreatment and subsequent annealing, which shows excellent cycle stability and superior rate capability as binder free anode for lithium ion batteries. It delivers initial discharge and charge capacity of 971 and 672mAhg−1 at 0.3C, maintaining of 700 and 669mAhg−1 after 70 cycles. After 60 cycles at various rates from 0.3 to 12C, the discharge capacity of the NiO/C-Ni electrode can gradually restore when reverting the rate to 0.3C, maintaining of 692mAhg−1 after 10 cycles. The impressive electrochemical performance demonstrates great potential of the NiO/C-Ni as anode for high performance lithium ion batteries. [Display omitted] •We fabricated porous NiO/C-Ni composite architecture.•The NiO/C-Ni can be used as binder free anode for lithium ion batteries.•The NiO/C-Ni exhibits superior electrochemical performance.
