Existing polyolefin-based battery separators have limitations with energy density and cell life, but our thinner separator allows for a safe increase in energy density, while being strong enough to suppress dendrite growth and increase shelf life. 

Elegus Technologies’ breakthrough Kevlar‐derived separator material has superior mechanical and electrochemical properties compared with current ion‐conducting membranes... it’s also capable of withstanding demanding operational needs, including high dimensional stability and high temperatures.

Research & Development


We are commercializing an aramid-based, ultra-strong battery separator made from high-performance nanoscale fibers developed at the University of Michigan. With technology stemming from multi-year, multi-million dollar research at U of M, we believe our separator is capable enough to solve the problems stemming from dendrite growth and thinness constraints.
