Li-ion Battery Electrode/Li Chips

How to make water-based electrode (graphite for anode) for your reference :
 
1.  Weight Ratio
1.  (All other weights depends on how much active power  your will use) :
○   Active Powder  :  92.5 %
○   CMC  :  1.5 %
○   SBR liquid  :  2.5 %
○   Conductive  :  3.5 %
○   Absolute Alcohol  :  15 ml/kg graphite
○   De-Ionized water  :  At least 125 % of graphite
2.  Make liquid thickening agent  :  heat up de-ionized water to 60C and then slowly put the CMC into the water and keep stiring until all of it is dissolved.

3.  Add alcohol into 125 % de-ionized water and then add conductive powder and stir.
4.  Put active powder into 3 and stir*
5.  Add SBR into 4 and stir*
6.  Take a little sample and test the viscosity, it is OK to coat if the viscosity is between 3000 - 5000 mpa.s.    If the viscosity is over this range, add more de-ionized water;   if the viscosity is lower, add more binder  (CMC and SBR)
 
* stirring by vacuum mixing is preferred
