Ultra-Uniform SnOx/Carbon Nanohybrids toward Advanced Lithium-Ion Battery Anodes

Ultra-uniform SnOx/carbon nanohybrids for lithium-ion batteries are successfully prepared by solvent replacement and subsequent electrospinning. The resulting 1D nanostructure with Sn-N bonding between the SnOx and N-containing carbon nanofiber matrix can not only tolerate the substantial volume change and suppress the aggregation of SnOx, but also enhances the transport of both electrons and ions for the embedded SnOx, thus leading to high cycling performance and rate capability.
