Carbon framework microbelt supporting SnO as a high performance electrode for lithium ion batteries.

Facile preparation of rational SnO-based electrode materials with excellent electrochemical performance is highly desired for lithium ion batteries (LIBs). In this work, carbon framework microbelt supporting SnO nanoparticles (CFM-SnO) were prepared via a facile electrospinning technology and annealing treatment process. The as-synthesized CFM-SnO electrode exhibits high reversible capacity of 768 mAh g at 0.2 A g after 200 cycles, high rate capacity of 535 mAh g at high current density of 3.2 A g. The facile synthesis and superior performance indicate that the as-synthesized CFM-SnO is a competitive anode material for LIBs.
