Technology Summary

In current technology, liquid plasticizers are added to the solid polymer electrolyte to increase conductivity of Li-ion batteries. This increases risks from the use of current flammable and toxic liquid plasticizers. This technology employs a newly developed electrolyte comprising a crystalline PEO6LiX complex that provides high room-temperature conductivity with minimal temperature dependence and decreased dendrite growth for increased battery life. Currently, Li-ion batteries using solid polymer electrolyte need to be warmed to 80°C to be functional. With cellulose-polymer composite electrolyte, no pre-warming is needed.
