Application Notes: 

1. Please click to see Procedure for Preparing Anode & Cathode Electrode Slurry.
2. Please keep the powder in vacuum box to avoid moisture.
3. Please bake the powder in a vacuum oven at 120 – 150 °C before making slurry and coating to ensure max. capacity.

A Step by Step Recipe for Preparing Cathode Electrode Slurry:

۱٫ Weight Ratio (All other weights depends on how much active powder you will use):
 Anode Active Powder – LiFePO4, LiCoO2… : 93.5%
 PVDF: 2.25%
 Conductive Super- C45: 4.0%
 NMP: 8/15 of the solid content by weight
2. Heat treat the active powder in the inert gas or vacuum environment, 120~140C for
two hours,
3. Grind mill the active and conductive power for about 30 minutes.
4. Heat up NMP solution to 80C. Slowly add PVDF and keep stirring until the PVDF is
fully dissolved. Usually this process will take around 120 minutes.
5. Add active and conductive powder into the slurry and stir. It is suggested to separate
the powders into 2 or 3 piles, add the first pile and mix for 30 minutes…add the second
pile and mix for another 30 minutes…until all the piles are finished. This will help
improve the mixing uniformity.
6. Take sample and test the viscosity. The recommended viscosity for the slurry is
around 6000 CPS.
