How to make a water-based electrode (graphite for the anode) for your reference:
1. Weight Ratio (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: 15ml/kg graphite
DI water: At least 125% of graphite
2. Make liquid thicken agent:
Heat up Deionized water to 60C and then slowly put the CMC into it and keep stirring unless all of them dissolved.
3. Put alcohol into 125% Deionized water and then to conductive powder to stir.
4. Put active powder into 3 and stir (better have vacuum mixing)
5. Put liquid thicken agent into 4 and stir (better have vacuum mixing)
6. Put SBR into 5 and stir (better have vacuum mixing)
7. Take a little sample and test the viscosity, if, in 3000-5000 mPa·s, it is OK to coat, if over, put some Deionized water, if less, the binder in (CMC and SBR)
