Sepion Power™

Performance. Without compromise.

Power is Sepion's high-performance separator — engineered for the battery platforms that refuse to trade speed for stability.

Sepion Power
Built for What's Next

Charging expectations are rising. Battery architectures are getting thinner. Performance margins are shrinking.

Power is a structurally engineered separator that enables faster charging, greater energy density, and more efficient system design — without increasing material mass.

  • Faster Charging

    Designed to support higher-rate ion movement under demanding conditions.

  • Greater Energy Density

    A thinner architecture that enables smarter pack design drop in gain of 1-5% Wh/L and Wh/kg.

  • Lower Material Intensity

    Up to 10x thinner coating and 20x lower coating material per m2.

  • Value Creating for All Chemistries

    Compatible with NMC, LFP, manganese-rich, semi-solid, and lithium-metal systems.

  • Improved Safety & Durability

    Reduced self-discharge controlling metal cross-talk.
