Title
PROCESS FOR TRANSFORMING SILICON SLAG INTO HIGH CAPACITY ANODE MATERIAL FOR LITHIUM-ION BATTERIES

Abstract

(EN) A method for transforming silicon slag into an anode material in lithium-ion batteries, comprising applying mechanical grinding, such as high-energy ball milling, to reduce particle size of silicon slag to micron and submicron sizes and/or to increase the amorphicity of the silicon slag powder. The silicon slag being used as raw material in fabricating the anodes has a composition of Si- SiC-C-SiO2, preferably having Si phase in both crystalline and amorphous states, and more preferably having Si phase only in amorphous state after a high-energy ball-milling thereof. The silicon slag has preferably a median particle diameter ≤20 μm after a high-energy ball-milling thereof and ≤2 μm after a slurry homogenization thereof. The silicon slag preferably contains 64 %wt. Si + 31 %wt SiC + 4 %wt. C + 1 %wt. SiO2.
