A new generation of high capacity, high discharge rate batteries requires a new generation of separator membrane. Elegus has designed a solution, a separator capable of withstanding demanding operation conditions and high currents. Elegus Technologies is commercializing an ultra-strong membrane made from high-performance nanoscale fibers developed at the University of Michigan. The patent-pending process is based on transformation of para-aramid threads into membranes with pores in the 5-50 nm range. Pores sized to prevent the growth of dendrites resulting in increased battery safety, longevity, and performance.
Our membranes satisfy the requirements of multiple energy storage technologies including lithium-ion batteries, lithium-sulfur batteries, lithium-air batteries, and more. Our membranes further address the current problems preventing successful implementation of these technologies. Testing has demonstrated the Elegus membrane’s advantages compared with leading competitors in aspects of internal resistance, mechanical strength, stable performance at high temperatures, safety, and longevity.
