The effect of introducing fluorine doping and sulfur vacancies on SnS as the anode electrode of LIBs: a density functional theory study.

As the anode material of LIBs, the SnS electrode boasts a reversible specific capacity as high as 1231 mA h g. Additionally, SnS possesses a CdI2-type layered structure with a layer spacing of 0.59 nm, which allows it to accommodate numerous lithium ions and facilitate rapid charge transfer.
