Wet-chemical synthesized MCMB@Si@C microspheres for high-performance lithium-ion battery anodes.

MCMB@Si@C microspheres, in which silicon nanoparticles were closely connected with mesocarbon microbeads (MCMBs) through strong chemical bonds, were synthesized as high-performance Li-ion battery anodes for the first time. Furthermore, the different surface functional groups, as interconnecting species, and their effects on the anode performance were characterized in detail.
