WebNano-Sn/Graphite anodes for lithium-ion batteries are successfully fabricated by the method of laser sintering on the copper current collectors. Then microstructures and electrochemical properties of the electrodes are investigated in details. WebThese heterointerfaces endow Gr@Nb2O5 anodes with high ionic conductivity and excellent structural stability. Consequently, Gr@10-Nb2O5 anode exhibits excellent cyclic stability and incredible rate capabilities, with 100.5 mAh g-1 after 10000 stable cycles at an ultrahigh rate of 20 C.
