Application Notes

• Please see the Step-by-Step Recipe for Preparing Anode & Cathode Electrode Slurry .
• Typical binder formulations:
  • Cathode: Cathode Powder + Conductive Graphite + PVDF + NMP
  • Anode: Anode Powder + Conductive Graphite + SBR + CMC
• You may use a Digital Battery Electrode Paste/Slurry Viscosity Tester to help achieve consistent slurry viscosity.
• Mix the solution thoroughly and make sure the binder is fully dispersed in the solution. A vacuum mixer is recommended.
• The product is not warranted for applications other than Li-ion anode slurry.
