Abstract: The invention provides a manufacturing method of a negative electrode material for a secondary battery. The manufacturing method includes following steps. A silicon-containing material is provided. The alkaline treatment is performed on the silicon containing material by placing the silicon containing material into an alkaline solution to obtain a modified silicon material. A peak intensity of the silicon-containing material at 3600 cm?1 to 3000 cm?1 in the spectrum by Fourier transform infrared spectroscopy (FTIR) is I0, and a peak intensity of the modified silicon material at 3600 cm?1 to 3000 cm?1 in the spectrum by FTIR is I1, wherein 0.9<I0/I1<1.

Abstract: A N-doped Si/C composite and a manufacture method thereof are provided. The N-doped Si/C composite includes a plurality of carbon-silicon particles. Each of the plurality of carbon-silicon particles includes one or more silicon particles and a carbon coating layer covering the one or more silicon particles, wherein a plurality of first nitrogen atoms is distributed in the one or more silicon particles of each carbon-silicon particle via a silicon-nitrogen bond, and a plurality of second nitrogen atoms is distributed in the carbon coating layer of each carbon-silicon particle via a nitrogen-carbon bond.

Abstract: The present invention discloses a method of using a waste silicon slurry. The method includes the steps of: (A) obtaining a waste silicon slurry containing a cutting oil and a metal; (B) treating the waste silicon slurry with a first reagent for reacting with the cutting oil; (C) treating the waste silicon slurry with a second reagent for reacting with the metal; (D) separating products resulting from step (B) and step (C) to obtain a solid portion; and (E) treating the solid portion with a third reagent to obtain products, including silicates and hydrogen gas.
