A kind of pyrolyzed hard carbon material, preparation and its applications are involved in this patent. The particle of this material has spherical or ellipsoidal morphology with smooth surface. The average particle size is in the range of 0.05/100 microns and the coarseness is not more than 0.5% of the particle size. The BET specific surface area is from 1 to 4000 square meters per gram. The inner pore size of the material is distributed between 0.3 and 50 nanometers, and the values of Le and La are from 1 to 20 nanometers. The real density of the material is from 0.8 to 2.2 grams per cubic centimeter and the tap density is 0.35/1.5 grams per cubic centimeter. The preparation of the material can be described as follows: firstly the precursors are mixed with solvents for homogenous distribution systems, then the mixtures are put into autoclave for dewatering. ollowing with washing, filtrating, drying and high-temperature treatment, the hard carbon material is obtained. This kind of material has wide utilizations, especially in using as negative electrode materials for secondary lithium batteries. |
