Li-Ion Battery Anode -Double Layer CMS Graphite Coated on Copper Foil (241mm L x 200mm W x 90um Thick) 5 sheets/bag bccf-ds

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)
