This product is a lithiated polyacrylic acid (PAALi) binder, developed specifically for silicon-based anode research. As a water-based binder with a pH of approximately 8, it minimizes interference with the initial Coulombic efficiency of electrode materials. PAALi offers strong adhesion between active materials and current collectors, along with robust electrochemical stability and high polymer strength to accommodate the volume expansion of silicon anodes during cycling, thereby enhancing cycle life. The binder can be used directly or diluted with deionized water, and it maintains its bonding performance under high-speed mixing, allowing flexible adjustment of slurry viscosity for coating processes. Available in 20g, 100g, 500g, and 1000g sizes, it suits both coin cell and pouch cell fabrication, making it a practical component for silicon-carbon anode development.
