Abstract
A ternary oxide based composite cathode material for a lithium-sulfur battery and a preparation method thereof are provided wherein the composite cathode material includes: sulfur and LiNiCoAlOor LiNiCoMnO(0<x<1, 0<y<1, 0<x+y<1), wherein a sulfur content is 50 wt. %-80 wt. %. The host has adsorption and catalytic effects on polar polysulfides, which can fix sulfur and promote electrochemical reactions, thereby preparing lithium-sulfur battery with high capacity and high stability.
