Product Description
Product Overview
PAALi (Lithium Polyacrylate Binder) is a high-performance, water-based adhesive specifically engineered for silicon-carbon anodes and silicon oxide (SiOx) electrodes in lithium-ion batteries. Manufactured by Kelude, this colorless transparent liquid delivers superior adhesion, electrochemical stability, and cycle performance for both experimental and commercial battery applications.
Key Features
- Excellent Adhesion: Strong bonding between electrode materials and current collectors
- High Polymer Strength: Withstands silicon anode volume expansion up to 300%
- Electrochemical Stability: Maintains performance over extended charge/discharge cycles
- Water-Based & pH-Balanced: pH ~8 (neutral) with no impact on initial Coulombic efficiency
- Ready-to-Use: Pre-lithiated formulation with consistent commercial production quality

Applications
Silicon-Carbon Anodes: Enhances cycle life and mechanical integrity
Experimental Batteries: Compatible with coin cells and pouch cells
Commercial Production: Scalable for high-volume electrode manufacturing
Usage Instructions
- Direct Use or Dilution: Apply as-is or dilute with deionized water
- Mixing Process: Add to powder in reactor - high-speed stirring won't break emulsion
- Slurry Control: Adjust water content to achieve desired viscosity
- Final Steps: Sieve, degas, and discharge slurry after dispersion
- Storage: Keep sealed at room temperature and avoid extreme temperatures
Why Choose PAALi?
Proven Performance: Widely adopted in silicon anode R&D applications
Process Flexibility: Suitable for both lab-scale experiments and industrial production
