摘要

Carbon-coated WSe2 nanomaterials are synthesized using solid-state reaction. The 75.57% crystal WSe2 nanoparticles are uniformly dispersed on a carbon matrix to form WSe2/C nanomaterials. The WSe2/C nanomaterials exhibit high discharge capacity and excellent cycling stability, which should be attributed to the buffering effect of the carbon matrix and improved conductivity of the composites.
