Sepion is an advanced materials company offering a platform of highly-tunable nanoporous membranes sold as key components to enable next-gen electric vehicle and portable electronics batteries, long-duration grid-storage batteries, and cost-effective water treatment.
How It Works
Sepion is commercializing a membrane platform with a suite of membrane products that has broad applicability to enhance the performance and economics of lithium batteries, flow batteries, hydrometallurgy, and heavy metal removal. At the heart of our platform technology is the ability to deliver robust, low-cost membranes with unmatched selective transport in formats that drop-in with existing manufacturing processes to minimize barriers to market entry. Our membranes function like nanoscale sieves, allowing only the smallest ions to pass at atomic level while blocking everything else to boost device performance.
