Key Applications in Battery Manufacturing
Cathode and Anode Binder
CMC serves as an effective binder for various electrode materials including lithium battery, natural graphite, MCMB, lithium titanate, tin-based, silicon-based negative electrode material, and iron-phosphate-based lithium cathode material.
- Binds active substance, conductive agent, and current collector together
- Firmly fixes electrode material on current collector
- Excellent conductivity reduces impedance between materials
- Enhances battery capacity and circulation stability
- Releases expansion and shrinkage during charging/discharging cycles
- Low usage with strong binding strength
- Safety, eco-friendly, and cost-effective solution
Gel for Cathode Protection
CMC forms uniform dispersive paste with electrolyte, maintaining even coverage around active granules.
- Good viscosity and liquid absorption properties
- Prevents battery active substance dehydration
- Enhances electrolyte absorption rate and reduces electric resistance
- Maintains performance under normal and high temperatures
- Improves high current discharge performance when mixed with sodium acrylate
Silicon-Based Electrode Applications
Strong hydrogen bond between CMC and silicon provides structural stability and performance enhancement.
- Maintains capacity over 1000mAh/g for at least 100 cycles
- Coulombic efficiency reaches 99.9%
- Strong shear-thinning property adjusts slurry rheology
- Cushions volume swelling of silicon-based electrode
- Promotes formation of stable SEI film
Graphite Modification
CMC coating improves natural graphite surface quality and electrochemical properties.
- Enhances graphite circulation property and capacity retention
- Prevents solvation and lithium ion co-embedding
- Increases retention rate of discharging platform and capacity
