NOVELTY - Silicon carbon negative electrode slurry comprises silicon-carbon negative electrode active material, a conductive agent, a binder, a thickener, and a solvent. The silicon-carbon negative electrode active material comprises a silicon-based negative electrode and a graphite negative electrode. The conductive agent comprises conductive agent A and conductive agent B. The silicon-carbon negative electrode slurry is prepared by stirring thickener in a solvent at a speed of 1000-2000 revolutions per minute (rpm) to become transparent, and added conductive agent A under stirring at a speed of 1000-2000 rpm for 60-120 minutes to obtain a dot-shaped conductive paste. The silicon-based negative electrode and conductive agent B are stirred at 500-1000 rpm for 10-60 minutes, and added to the dot-shaped conductive paste under stirring at 1000-2000 rpm for 60-120 minutes to obtain a silicon-based conductive paste. USE - Silicon carbon negative electrode slurry. ADVANTAGE - Adv: --- The silicon carbon negative electrode slurry forms a more complete three-dimensional conductive network structure, and improves the electronic conductivity of the silicon carbon anode. DETAILED DESCRIPTION - Silicon carbon negative electrode slurry comprises silicon-carbon negative electrode active material, a conductive agent, a binder, a thickener, and a solvent. The silicon-carbon negative electrode active material comprises a silicon-based negative electrode and a graphite negative electrode. The conductive agent comprises conductive agent A and conductive agent B. The silicon-carbon negative electrode slurry is prepared by stirring thickener in a solvent at a speed of 1000-2000 revolutions per minute (rpm) to become transparent, and added conductive agent A under stirring at a speed of 1000-2000 rpm for 60-120 minutes to obtain a dot-shaped conductive paste.

The graphite negative electrode is added to the silicon-based conductive slurry under stirring at 1000-2000 rpm for 60-180 minutes to obtain a primary negative electrode slurry. The binder is added to the primary negative electrode slurry under stirring at 500-1000 rpm for 30-60 minutes, tested the viscosity and fineness of the slurry, and discharged the material to obtain the silicon-carbon negative electrode standard slurry.
