Electrode sheet preparation, the first active substance (such as lithium cobaltate, graphite, etc.), conductive agent (such as acetylene black, carbon nanotubes, carbon fiber, etc.), adhesive (such as polyvinylidene fluoride, polyvinylpyrrolidone, sodium carboxymethyl fiber, styrene butadiene rubber emulsion, etc.) and solvent (such as N-methylpyrrolidone, water, etc.) together to make electrode paste. Then it is coated on the fluid collecting surface of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnet for iron removal as required, and then dried to obtain the battery pole sheet.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC The performance of electrode slurry for removing iron has an important effect on the performance of lithium-ion batteries. The more evenly divided each group in the electrode paste, the better the processing performance of the electrode sheet, and the impedance distribution of the electrode is uniform, the greater the role of the active substance can be played during charging and discharging, and the average gram capacity will be improved, thereby improving the performance of the whole battery.
The traditional preparation method of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic slurry is to disperse the conductive agent with thickener solution at high speed, and then add the negative active substance, after stirring for a certain time, The final graphite negative slurry was obtained by adding binder and stirring for a short time.
