Hollow MoS2/Co nanopillars with boosted Li-ion diffusion rate and long-term cycling stability.

Hollow MoS2/Co-0.1 nanopillars were successfully synthesized by sulfurizing CoMoO4 and subsequent acid etching, which were used as the anode material for lithium ion batteries. The introduction of suitable metal Co into MoS2 nanopillars effectively accelerates electron/ion transport kinetics, leading to high specific capacity and superior rate capability and cycling stability.
