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.

Abstract

A CoMo2S4/Ni3S2 heterojunction is prepared with a high charge carrier mobility and many active sites. This CoMo2S4/Ni3S2 electrode requires an overpotential of only 51 mV to drive a current density of 10 mA cm−2 in 1 M KOH solution. Impressively, the as-prepared electrode exhibits a high stability, with ∼100% of the current density remaining in the ∼50 h amperometric curve both at 10 mA cm−2 and 240 mA cm−2.
