Claim 0:
1. A ternary oxide based composite cathode material, for a lithium-sulfur battery, comprising: sulfur and LiNi0.8Co0.15Al0.05O2 or LiNixCoyMn1-x-yO2 (0<x<1, 0<y<1, 0<x+y<1) as a host, wherein a sulfur content is 50 wt. %-80 wt. %;
wherein the LiNixCoyMn1-x-yO2 has a layered structure, which is a secondary particle formed by accumulating primary particles; the secondary particles are spherical with a diameter of 2-25 μm; the LiNixCoyMn1-x-yO2 has a specific surface area of 10.0-100 m2 g−1, and a tap density of 2.0-2.6 g cm−3.
