Tsinghua University applied for a patent for the preparation of silicon oxide carbon electrode materials, and the service life was increased by 2-3 times.

Financial news on March 2, 2024, according to the announcement of the State Intellectual Property Office, Tsinghua University applied for a project called "a preparation method of silicon oxide carbon electrode material", public number CN117623313A, the application date is November 2023.

The patent abstract shows that the invention provides a preparation method for a silico-carbon electrode material. By impregnating a silicon source into a template agent solution, and then adding carbon nanotubes or fiber materials, the composite material of carbon materials and all-silicon nanosheets is obtained through filtration, drying and roasting; The composite material was carbonized and pulverized in the alkaline solution of phenolic resin to obtain silica carbon particles. Then the silica carbon particles were etched and heat treated to obtain the silica carbon electrode material rich in 0.5 ~ 2nm pore diameter. Because the all-silicon nanosheets are lamellar structures with relatively uniform pore structure and nanometer size, they are easy to react. The obtained silicon oxide carbon electrode material has excellent product consistency and spatial uniformity, and the service life is increased by 2-3 times.
