Application of CMC in battery

CMC product is main adhesive of water-based negative electrode materials and is widely used by battery manufacturers. Better adhesive for large battery capacity, long cycle life and low internal resistance. Therefore we improve production technique to develop battery exclusive used products.

Effect of CMC in battery:
Improve dispersing stability of insoluble components in solution
Dispersing effect on negative electrode material and conductive agent
Thickening and anti-sedimentation effect on cathode sizing agent
Improve liquidity of insoluble components in solution
Auxiliary binding effect
Stabilizing processing property of electrode and promote cycle property of battery
Improving bearing strength of pole piece

Features of Weiyi CMC products
High degree of substitution and strong binding force
Fine solubility, high dissolving speed, fine transparency of aqueous solution and fine liquidity
Stable viscosity, narrow distribution of molecular weight
High purity and low metal content
Fine emulsifying dispersibility and curing dispersibility
High degree of dissolving
Models: BH90-II, BH90-III, BH2000, 2020, 2030, 2400, 2500
