| description | The invention relates to high-stability graphite negative electrode paste and a preparation method thereof. The preparation method comprises the steps of adding 50wt% of CMC gum and SP into a mixer, slowly mixing and then mixing for 1.5h at a rotation frequency of 25Hz and a revolution frequency of 25Hz; adding 25wt% of CMC gum and graphite, mixing, scraping and mixing for 2.5h at the rotation frequency of 35Hz and the revolution frequency of 25Hz; adding 25wt% of CMC gum, mixing and then mixing under the vacuum of -0.08MPa to -0.1MPa for 2h at the rotation frequency of 25Hz and the revolutionfrequency of 25Hz; and adding SBR and NMP, mixing under the vacuum of -0.08MPa to -0.1MPa for 1h at the rotation frequency of 10Hz and the revolution frequency of 15Hz, slowly mixing for a moment anddischarging. According to the paste provided by the invention, the viscosity increments of the paste after standing for 24 and 48h are smaller than those of commercial paste through a viscosity test,so that the paste provided |
