PAALi (Lithium Polyacrylate Binder) is a high-performance, water-based adhesive specifically designed for silicon-carbon anodes and silicon oxide (SiOx) electrodes in lithium-ion batteries. Produced by Kelude, this colorless, transparent liquid offers superior adhesion, electrochemical stability, and cycle performance, making it ideal for experimental and commercial battery applications.

2. Key Features

Excellent Adhesion: Strong bonding between electrode materials and current collectors.
High Polymer Strength: Withstands silicon anode volume expansion (up to 300%!).(MISSING)
Electrochemical Stability: Maintains performance over long charge/discharge cycles.
Water-Based & pH-Balanced: pH ~8 (neutral), no impact on initial Coulombic efficiency.
Ready-to-Use: Pre-lithiated, commercially mass-produced with consistent quality.
