Abstract

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.
