Stable cyclic performance of nickel oxide–carbon composite anode for lithium-ion batteries
Nickel oxide (NiO) directly grown on nickel foam is regarded as a promising lithium ion battery anode material which shows good cyclic and rate performances with a theoretical specific capacity of 718 mAhg−1. In this study, we demonstrated a carbon-incorporated NiO anode (NiO–C) with a capacity per...
