Facile preparation of nano-micro structure PbSbO2Cl as a novel anode material for lithium-ion batteries

Abstract

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.
