A new anode comp.sition SiO/CNTs (car.on nanotubes) has been p.ep.r.d by chemical vap.r.dep.sition (CVD) method. The r.sults of scanning electr.n micr.scop. (SEM) confir. that CNTs dep.sit on small SiO p.r.icles,for. a cage,and enwr.p.SiO p.r.icles tightly. SiO/CNTs anode comp.sition exhibits an initial dischar.e and char.e cap.city of 1171 and 789 mAh/g,and maintains a r.ver.ible cap.city of 500 mAh/g after.80 cycles. The imp.ovement of the cyclic p.r.or.ance for.SiO/CNTs comp.sition is r.lated to the maintaining of the electr.c networ. dur.ng cycling,which benefits fr.m a tight contact between CNTs and SiO p.r.icles.
