  • 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 :  15 ml/kg graphite
    ○  Deioin water :  At least 125 % of graphite

    2.  Make liquid thicken agent :  Heat up deion water to 60C and then slowly put the CMC into it and keep stiring unless all of them dissolved.
    3.  Put alcohol into 125% deion 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 mps, it is OK to coat, if over, put some deion water, if less, binder in  (CMC and SBR)
  • Note :  Please store moisture sensitive consumables in vacuum storage box, which will help prevent damages and prolong the integrity of the material.    Click here for equipment selection
