Microwave-hydrothermal synthesis of W0.4Mo0.6O3 and carbon-decorated WOx-MoO2nanorod anodes for lithium ion batteries

Abstract

W_0.4Mo_0.6O₃ and carbon-decorated WO_x-MoO₂ (x = 2 and 3) nanorods have been synthesized by a microwave-assisted hydrothermal process. The carbon-decorated WO_x-MoO₂ nanorods exhibit excellent capacity retention as the carbon provides an elastic matrix for absorbing the volume expansion–contraction smoothly and prevents aggregation of the nanorods during cycling.
