This product is a hydrophilic polysaccharide extracted from seaweed, designed for use as a binder in advanced energy materials, particularly in silicon cathode and silicon-carbon cathode systems. Sodium Alginate exhibits a viscosity of 200±20 mPa·s and dissolves in water to form a viscous colloidal solution, remaining stable upon heating and insoluble in organic solvents or acids below pH 3. It serves as a stabilizer, thickener, and artificial semi-permeable membrane material, with research applications in biochemistry for cell and enzyme immobilization, such as fixing glutamate decarboxylase via alginate matrices that can be liquefied with chelating agents. Its moisture sensitivity and consistent rheological properties make it a reliable binder for electrode fabrication in battery research.
