Sepion Technologies develops advanced polymer materials that control molecular transport for energy and industrial systems. Its platform focuses on separators—thin layers that influence ion movement, battery performance, and stability—using nanoscale material design to support improvements across large-scale applications.
The company offers two commercial separator products. Sepion Power™ is designed to optimize performance, including charging speed, energy density, and system efficiency. Sepion Shield™ focuses on protection and stabilization, with the aim of enhancing safety, extending cycle life, and supporting more stable system costs. Both are designed as direct replacements for ceramic-coated separators, compatible with lithium-ion chemistries and existing production lines without retooling. Sepion says its technology is in commercial production and supported by a global toll-manufacturing network.
Applications include mobility, energy storage, consumer electronics, and AI infrastructure. Beyond its current battery products, Sepion Frontier explores uses in water purification, resource recovery, industrial and gas separations, critical metal production, and emerging energy architectures. The company’s stated mission is to help sustainably power people and infrastructure through advanced materials.
