  • Publication number: 20250233127
    Abstract: A method for preparing a high-performance silicon-carbon composite graphite material includes grinding and sieving a graphite material, a silicon material and a binder; the grinded and sieved graphite material, silicon material and binder being put into a high-speed mixer and mixed evenly, and then put into a mold and pressed into ingots; and using a heating treatment and carbonizing the ingots in an inert gas, cooling the ingots to room temperature, then the ingots being pulverized, grinded, mixed, sieved, and magnetic separation to obtain the high-performance silicon-carbon composite graphite material. The method improves the problem of large volume changes in silicon material during the charging and discharging process which usually results in materials powdered and structure collapse. The silicon material, the graphite material and the binder are easy to obtain, have micron grade particle sizes, are suitable produced by factory scale, and are conducive to commercialization.

  • Patent number: 5651950
    Abstract: Disclosed is a process for producing silicon carbide. The process includes the steps of (1) mixing .beta.-resin extracted from coal-tar pitch with .alpha.-resin and silica gel; (2) after being dried, grinding the mixture to powder; (3) heating the powder in an atmosphere of nitrogen with a temperature in the range from 300.degree. C. to 480.degree. C. until mesophase is cultured; and (4) proceeding the heat treatment with a higher temperature in the range from 900.degree. C. to 1200.degree. C. for a period in the range from 2 to 7 hours. By the process, the production of silicon carbide can be carried out at low temperatures so that it is cost-effective in energy consumption.
