Conductive Graphite powder

KS-6 Conductive Graphite Powder is a high-purity, fine graphite conductive additive used in lithium battery cathode and anode electrode formulations. In composite electrodes, graphite forms an electron-percolation network between active-material particles and the current collector, lowering internal resistance and improving high-rate behaviour.

Working principle in electrodes

During slurry mixing and coating, KS-6 graphite distributes through the binder matrix (PVDF/NMP systems or water-based CMC/SBR systems). Its platelet-like conductive pathways reduce contact resistance and help maintain electrical continuity during calendaring and cycling, supporting stable impedance and power performance.
