Elegus, a University of Michigan startup that has developed a Kevlar-derived dendrite-suppressing membrane exhibiting high modulus, ionic conductivity, flexibility, ion flux rates and thermal stability for Li-ion batteries (earlier post), has formed a $1.5-million joint venture with XALT Energy and Energy Power Systems. Additional terms of the joint venture were not disclosed.
The Elegus separator allows for increased energy density in lithium-ion cells without compromising safety.
The Elegus separator will be the solution that will enable XALT to achieve its higher energy roadmap while maintaining safety. As improvements in technology allow higher and higher energy density in lithium-ion batteries, safety issues become far more challenging. Elegus’ advanced separator solution provides excellent electrical performance and dimensional integrity.—Dennis Townsend, chairman of the XALT’s board of directors
