High performance freestanding stainless steel net@MoS₂ lithium-ion battery anode material

In order to improve the electrical conductivity and stability of the MoS₂ electrode material of lithium-ion batteries (LIBs), the nano-MoS₂ is compounded with other more conductive materials. MoS₂ nanoflowers were prepared in situ grown on stainless steel net (SS) via a facile hydrothermal method, developing SS@MoS₂ anode material with self-supporting structure without binder. The nanoflowers structure and the enhanced conductivity of MoS₂ by SS can ameliorate the diffusion rate of both Li and electrons, as well as the electrode reaction kinetics. The SS@MoS₂ electrodes display excellent lithium storage performance, especially remarkable high-rate capabilities in LIBs. And the specific capacity of 862.1 mA·h/g can still be obtained after 600 cycles at a high current density of 1 000 mA/g.
