Sepion Shield™

Performance. Protected.

Shield is Sepion's stability-optimized product — engineered to strengthen safety, extend system life, and stabilize cost at scale — without compromising performance.

Sepion Shield
Built for systems that must endure

Scale is increasing. Energy systems are operating longer. Risk tolerance is shrinking.

Shield is a structurally engineered separator that enhances long-term durability, reduces self-discharge — while preserving round trip energy efficiency.

  • Extended Cycle Life

    Blocks harmful metal ions from reaching the anode, eliminating the most common cause of capacity fade.

  • Pack Efficiency Without Compromise

    Thinner architecture, smaller footprint, more energy per container — without trading away durability.

  • Enhanced Safety

    Prevents the metal ion crossover and plating that drive late-life safety failures and self-discharge.

  • $/kWh Cost Reduction

    Stabilizes manganese-rich, LMFP, and lower-grade LFP and NMC cathodes without compromising output, improving asset bankability.
