Under other conditions being the same, the inner battery prepared with positive slurry has better rate charge-discharge performance, high power density and long cycle life. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic preparation of positive slurry steps are as follows: add 34.4KGN-methylated roxene in the vacuum mixer, then add 0.66Kg polypartial gas ethyme PVDF, public conversion, self-conversion rate of 30min mixing;
Add 2.13Kg conductive agent, public conversion, self-conversion speed of mixing; Add 15Kg meter to drill out lithium acid material, public conversion, self-conversion speed of mixing; Adding 15KgPTMS LITHIUM COBALT ACID MATERIAL MAGNETIC to remove iron, the instrument drilled out the lithium acid material, and the speed of conversion and self-conversion was mixed for 30min; Vacuum, when the vacuum degree reaches 0.0lMPa, continue pumping for 3min, continue to rotate 50Hz in the vacuum state, and the speed of self-transformation will be mixed;
After the end of mixing, turn off the vacuum, use nitrogen or nitrogen to break the vacuum, open the mixing bucket, add ethanol, and then vacuum. When the vacuum degree reaches transformation, continue pumping for another 3 minutes, and then transform in the vacuum state, the rotation speed of mixing for 30 minutes; After mixing, turn off the vacuum, break the vacuum with nitrogen or nitrogen, open the mixing bucket, pass the slurry through the 100-mesh screen, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC to remove particles and impurities, and then coating can be done.
