Commercial Today in Batteries
The same platform that is commercial in battery separators today has proof-of-concept across five additional application domains, backed by 150+ experiments and a 20-patent IP portfolio.
The performance of modern systems is ultimately limited by materials
Energy storage
Water purification
Industrial separations
How precisely we can control what moves — and what doesn’t — defines what these systems can achieve.
Sepion’s platform enables new levels of control at the nanoscale, opening possibilities for industries far beyond today’s commercial focus.
Energy infrastructure
Energy systems are scaling rapidly. Electric grids, renewable integration, and digital infrastructure all depend on reliable large-scale energy storage. These systems require materials that perform safely and consistently over decades of operation.
The opportunity
Sepion's platform enables precise control over ion transport and structural stability. Sepion: Frontiers explores separator architectures optimized for:
- Manganese-rich (LMR) Cathodes
- Silicon anodes
- Lithium-metal anodes
- Sodium ion separators
Materials define how energy infrastructure scales.
Water systems
Clean water systems depend on efficient separation. Removing contaminants, recovering valuable materials, and recycling water all require membranes capable of precise molecular control. Today's technologies are energy intensive and limited in selectivity.
The opportunity
Advanced polymer architectures can redefine how ions and molecules move through filtration systems. Sepion: Frontiers explores new approaches to:
- Direct lithium extraction (DLE)
- Hydrometallurgy
Improving separation efficiency could transform water systems across industry and infrastructure.
Industrial Separations
Many industrial processes depend on separating gases and molecules efficiently. These separations often require large amounts of energy and specialized equipment. The limiting factor is frequently the material used to control molecular flow.
The opportunity
Sepion's nanoscale polymer architectures offer new possibilities for membrane design. Sepion: Frontiers investigates applications including:
- Gas separation
- Molecular filtration
- Industrial process efficiency improvements
Better materials can dramatically reduce the energy required to move and separate molecules.
The same platform that powers our commercial products also drives our research
