Mesoporous nanonickel oxide: Anode with good initial discharge capacity and efficiency in lithium ion batteries at 1Â C rate

Highlights
- NiO with nanoparticle size (3 nm), large surface area (230 m2/g) and mesoporous structure enhanced the initial discharge capacity value at 1 C rate.
- The material delivered 1070 mA h/g at the first discharge capacity at 1 C rate.
- Nanonickel oxide showed a good efficiency through charge-discharge cycles.
