Facile preparation of nano-micro structure PbSbO ₂ Cl as a novel anode material for lithium-ion batteries

We report the development of PbSbO2Cl as a new anode material for lithium-ion batteries. It is prepared by a simple hydrothermal method from Pb(NO3)2 and SbCl3. The as-prepared PbSbO2Cl shows a well-dispersed nano-micro structure with particle sizes of 200–500 nm. The initial discharge capacity of PbSbO2Cl is 1011.0 mAh g−1 corresponding to 14.6 Li per formula storage in the structure. In the inverse charge process, a reversible capacity of 731.8 mAh g−1 can be delivered. This suggests that PbSbO2Cl may be a promising high-capacity anode material for lithium-ion batteries.
