Polyethylene Oxide PEO Solid Electrolyte Powder

This high-purity Polyethylene Oxide (PEO) powder is designed as a polymer solid electrolyte substrate for advanced battery research. Supplied without lithium salts, it enables researchers to tailor electrolyte formulations by adding lithium salts, plasticizers, or fillers as needed. Available in two grades—E-30 (average molecular weight 380,000) and E-60 (average molecular weight 1,100,000)—the material offers distinct viscosities and ionic conductivities, with E-30 providing approximately 6.29×10⁻⁶ S/cm and E-60 around 1.41×10⁻⁶ S/cm at room temperature. The powder maintains a neutral pH, low thermal weight loss (0.5%), and minimal ash content (0.3%), ensuring reliable performance. It is commonly applied in fabricating solid-state electrolytes for lithium batteries, where the PEO matrix serves as a flexible, processable platform for ion transport and compositional optimization.
