  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)
