    How to make water-based electrode (graphite for 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)
