Oxygen-incorporated crystalline/amorphous heterophase cobalt vanadium selenide nanoplates with dense interfacial sites for robust lithium–sulfur batteries

Oxygen-incorporated heterophase cobalt vanadium selenide nanoplates with dense crystalline/amorphous interfacial sites (DC/A O-CoVSe NPs) are developed as high-efficiency sulfur electrocatalysts for lithium–sulfur batteries.
