Beschreibung
Zusammenfassung:	The invention provides a preparation method of a nanometer silicon powder suspension, a detection method of a dispersion effect of the nanometer silicon powder suspension and application of the nanometer silicon powder suspension. The preparation method of the nano silicon powder suspension comprises the following steps: carrying out hydrophilic group modification on coarse nano silicon powder to obtain hydrophilic group modified nano silicon powder; carrying out first mixing and stirring on the hydrophilic group modified nano silicon powder and a dispersing agent solution to obtain a nano silicon powder suspension; wherein the particle size of the coarse nano silicon powder is 50-120nm; the dispersing agent solution comprises a mixed aqueous solution of a dispersing agent containing an electronegative group and a high-molecular dispersing agent; or the dispersing agent solution comprises a mixed aqueous solution of a dispersing agent containing an electronegative group and a nonionic steric hindrance type di
