Solid Electrolytes for Lithium-ion Batteries
At NEI Corporation, we fuel the future of energy storage with our industry-leading selection of solid-state electrolyte materials. If you’re developing next-generation lithium-ion batteries, our advanced materials can help you achieve groundbreaking performance. One such material are our polymer-based solid electrolytes.
Polymer-based solid electrolytes hold great potential for revolutionizing battery technology due to their inherent safety, flexibility, and potential for high energy density. Our solid polymer electrolytes are designed for rechargeable solid-state lithium batteries and consist of specially synthesized polymers combined with highly conductive lithium salts. These materials are not powders, but rather chunky polymer solid pieces that can be dissolved in polar solvents.
NEI’s polymer-based solid electrolytes are available in quantities including 10 grams, 25 grams, 50 grams, 100 grams, 250 grams, 500 grams, 1 kilogram and more. Browse our extensive and growing selection of solid electrolytes and find the perfect fit for your lithium-ion battery needs!
