PEO Polymer Electrolyte Powder, Poly(ethylene Oxide) (PEO), Polymer Electrolyte Matrix for Solid-State Battery Research

About this item

• Versatile Polymer Electrolyte Matrix: serves as a high-performance polymer matrix for solid-state electrolytes composite polymer electrolyte membranes and lithium metal battery research; lithium salts and functional additives can be incorporated as needed for tailored electrolyte formulations
• Dual Molecular Weight Grades: available in two grades PEO-30 (Mw ~380,000 low viscosity for solution casting) and PEO-60 (Mw ~1,100,000 high viscosity for mechanical strength) providing flexible processing options for diverse electrolyte membrane fabrication requirements
• Excellent Ionic Conductivity: demonstrates high ionic conductivity when complexed with lithium salts (e.g., LiTFSI) with typical values of 6.29 x 10⁻⁴ S/cm (PEO-30) and 1.41 x 10⁻⁴ S/cm (PEO-60) at EO:LiTFSI = 15:1 providing reliable benchmarks for solid-state electrolyte R&D
• High Purity & Consistent Quality: certified with high purity pH 7 low ash content ≤0.3% and thermal weight loss ≤ 0.5% ensuring minimal impurities and excellent batch-to-batch reproducibility for demanding polymer electrolyte research
• Good Solubility & Processability: readily soluble in common organic solvents (acetonitrile THF etc.) enabling processing into free-standing polymer electrolyte membranes binders and protective layers while supporting a wide range of electrolyte fabrication methods
• Storage & Usage Instructions: stable in air but should be stored sealed in a dry environment to prevent moisture absorption; supplied as pure PEO powder without lithium salts and should be dissolved before adding lithium salts (e.g., LiTFSI) plasticizers inorganic fillers organic fillers or other polymers according to experimental requirements
