and good long-term cycling stability (500 cycles without decaying) were also obtained. These excellent performances are attributed to the unique structure of the composite material. First, the empty space inside the nanotubes and the thin tube walls are beneficial for the diffusion of Li+ions. Se...
Kim et al. synthesized a layer-structured Sn4P3 by HEMM and tested it as an anode material for Li-ion batteries.218 The Sn4P3 electrode showed high ?rst discharge and charge capacities of 1130 mAh g?1 and 900 mAh g?1, respectively. They suggested the following discharge reaction: Sn4P...
