英文摘要	a novel si/porous-c composite with buffering voids was prepared by the co-assembly of phenolformaldehyde resin, sio2 and si nanoparticles, followed by a carbonizing process and subsequent removal of sio2 template. si nanoparticle was coated with a layer of porous carbon shell with rationally designed void in between which provides the accommodating space for the volume change of si over cycling. the as-prepared composite electrode exhibited good electrochemical performances as an anode material in lithium-ion cells, showing a stable reversible capacity of 980 mah g(-1) over 80 cycles with small capacity fade of 0.17%/cycle and high rate capability (721 mah g(-1) at 2000 ma g(-1)).
