摘要

Tin-based compounds/carbonaceous materials composite anodes for Li-ion rechargeable batteries attracted much attention because of their high capacity and improved cycleability. Two novel Sn compounds/mesophase graphite powders (MGP) composite materials for lithium-ion batteries were prepared by the electroless plating method. The electroless-plated composite anodes exhibited much higher capacity than the bare MGP without appreciable fading. The capacity retention after 20 cycles of the Sn-P-O/MGP and Sn-P-Ni/MGP composites was 82.4% and 94.3%, respectively, of their highest capacity. Therefore, introducing Ni into the composite anodes could effectively improve the cycling stability.
