Product application plan
1. materials, proportion and design parameters:
Ratio: MAG-BCM: conductor: CMC:SBR=95.4%:1.0%:1.6%:2.0% (mass percent), solid content for 40~45%;
Cathode design capacity on 330mAh/g, excess is at least 5%.
Compaction density of negative 1.50~1.55g/cm ³,


2. Pulp production:
2.1 required to measure water with CMC, CMC glue added slowly to the water, until no particles in liquid, gel until transparent, stirrer speed revolution speed for 25Hz/min for 30Hz/min, 3h and then rest for 12-24 hours; in the mixing process required circulating water cooling at a temperature not exceeding 35 ℃.
2.2 required number of conductive agents joined the mixer CMC solution and vacuum to do before -0.08mpa, mixing 2H, stirrer speed revolution speed for 30Hz/min for 35Hz/min;
2.3 include the required number of graphite in the mixer mixing 3H and vacuum below -0.08mpa, stirrer speed revolution speed for 30Hz/min for 35Hz/min;
2.4 include the required number of SBR in the mixer mixing 1H, stirrer speed revolution speed for 15Hz/min for 20Hz/min;
2.5 include the required number of H2O in the mixer mixing 2H and vacuum below -0.08mpa, stirrer speed revolution is 15Hz/min, since the speed is 20Hz;
2.6 vent to atmospheric pressure, after passing the test size, 120 mesh. Slurry viscosity 1800~2500CP, liquid slurry, paste derived from delicate surfaces, gloss; size in use during vacuum slow stirring, not on hold for a long time.


3. Film production:
3.1 according to the design parameters of the coating.
3.2 pole roller: compaction density of 1.50~1.55g/cm ³, proper adjustment of the roller, roller smooth sheet satisfy processing requirements.
Note: our plant for Guangzhou Guan Yu model S-G vacuum mixer


Process for using reference above, according to the company's technology and equipment to make proper adjustments.
