Cell Lab Polyethylene Oxide (PEO) Powder [250 g, Mv 300,000–1,000,000]

High molecular weight solid polymer electrolyte for advanced lithium and sodium battery research

The Cell Lab Polyethylene Oxide (PEO) powder is a high-purity polymer electrolyte material developed for next-generation solid-state lithium-ion and sodium-ion batteries.
Featuring molecular weights between 300,000 and 1,000,000, this semi-crystalline polymer exhibits excellent film-forming ability, ionic conductivity, and mechanical flexibility, making it ideal for solid polymer electrolyte membranes and composite electrolyte fabrication.

Engineered for research and pilot-scale use, PEO provides stable ion transport pathways when combined with lithium salts such as LiTFSI, LiClO₄, or LiPF₆, and can be processed by solution casting, electrospinning, or hot pressing.

Key Features

• Wide Molecular Weight Range (Mv 300k–1M) – Enables control over electrolyte viscosity, film flexibility, and mechanical strength.

• Excellent Ionic Conductivity – Supports Li⁺ and Na⁺ transport when complexed with lithium or sodium salts.

• Superior Film-Forming Capability – Forms smooth, flexible solid polymer films suitable for membrane or separator use.

• High Purity and Batch Consistency – Viscosity 400–800 cP (0.2 % in H₂O, 25 °C) ensures uniform processing quality.

• Versatile Processing Methods – Soluble in water and alcohols for solution casting or melt-processing into polymer electrolyte films.
