A nano-sulfur composite anode material for rare earth lithium-sulfur battery and its preparation method thereof, wherein the preparation method includes the steps of providing a carbon nanotube and sublimed sulfur, adjusting concentration based on percentage weight, mixing by milling, burning under negative pressure in Argon gas for 5 hours at 200° C.˜300° C. and 300° C.˜400° C. respectively, and obtaining a final product of nano-sulfur composite anode material for rare earth lithium-sulfur battery. By means of the preparation method of the present invention, the nano-sulfur composite anode material has a particle size <1 micron, a high capacity which is greater than 1000 mAh/g, and a long cycle life (>1000 times). The preparation method has the advantages of simple, low cost and high performance, thereby suitable for industrial production. The rare earth lithium-sulfur battery with the nano-sulfur composite anode material has the advantageous features of high energy density, high cycle performance, environmental friendly and low cost. |
