文摘
- •
Liquid phase plasma process was used to synthesize cobalt-manganese oxide/carbon composite.
- •
Uniform dispersion of spherical metal oxide nanoparticles on the carbon surface.
- •
The initial concentration of precursor influenced the composition of the nanoparticles precipitated.
- •
The nanoparticles were bimetallic oxide nanoparticles composed mainly of Co2+ and Mn3+.
- •
The metal oxide nanoparticles improved the cyclic stablilty and reduced equivalent series resistance.
