3D CoMoSe₄ Nanosheet Arrays Converted Directly from Hydrothermally Processed CoMoO₄ Nanosheet Arrays by Plasma-Assisted Selenization Process Toward Excellent Anode Material in Sodium-Ion Battery.

ABSTRACT: In this work, three-dimensional (3D) CoMoSe₄ nanosheet arrays on network fibers of a carbon cloth denoted as CoMoSe₄@C converted directly from CoMoO₄ nanosheet arrays prepared by a hydrothermal process followed by the plasma-assisted selenization at a low temperature of 450 °C as an anode for sodium-ion battery (SIB) were demonstrated for the first time. With the plasma-assisted treatment on the selenization process, oxygen (O) atoms can be replaced by selenium (Se) atoms without the degradation on morphology at a low selenization temperature of 450 °C. Owing to the high specific surface area from the well-defined 3D structure, high electron conductivity, and bi-metal electrochemical activity, the superior performance with a large sodium-ion storage of 475
