Ni-Mo / Synthesis method of Silicon/Carbon nanofibers composites based on Ni and Mo catalysts and manufacturing method of Lithium Secondary Batteries with anode materials of it

摘要

(A) mixing nickel nitrate and ammonium molybdate in a molar ratio of any one of 10: 0, 8: 2, 6: 4, 5: 5, 4: 6, 2: 8, And dissolving in distilled water together with the support; (b) dropping the solution of precipitant dissolved in the dissolved solution and distilled water together with another distilled water, mixing and stirring; (c) filtering the stirred solution and drying the precipitate to form a Ni-Mo binary metal catalyst powder; (d) mixing the silicon and the bimetallic catalyst catalyst in a weight ratio of 8: 2, 6: 4, 5: 5, 4: 6 and 2: 8 to form a dispersion solution, ; And (e) synthesizing a composite material of silicon / carbon nanofibers by using chemical vapor deposition on the composite powder. As described above, the present invention provides a carbon nanotube having uniformly grown carbon nanofibers, a high average value of carbon elements, a low amorphousness, an excellent crystallinity and a very high specific surface area, Provided is a method for producing a composite fiber material, and a method for manufacturing a secondary battery having a high charge / discharge capacity efficiency by using the method.
