文摘
- •
Low cost Ni(OH)2@C and NiO@C hybrids have been synthesized through in situ seeded deposition on carbon spheres.
- •
The surface absorption of the Ni2+ cations strongly effects on the deposition in absence of sodium acetate.
- •
The enhanced nanoelectrical conductivity on NiO@C hybrids was higher than that on NiO&C composites.
- •
The cycling stability and rate capability of LiBs on hybrids higher than simple composites.
- •
The charge transfer resistance on hybrids is lower than that on composites.
