Sn(salen)-derived SnS nanoparticles embedded in N-doped carbon for high performance lithium-ion battery anodes

By simple pyrolysis of a tin salen complex [Sn(salen)] and sulfur powder at 700 degrees C, SnS nanoparticles with similar to 20 nm thickness homogeneously embedded in nitrogen-doped carbon are prepared. When applied as lithium-ion battery anodes, the SnS/N-C nanocomposites exhibited long cycling stability and excellent rate capability.
