Sepion Shield™ — Durability by Design

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 and Calendar Life
Suppresses metal-ion crossover and dendrite formation. Warranty headroom, lower augmentation cost, and degradation curves lenders trust.
Stabilizes Low-Cost Cathodes
Stabilizes manganese-rich, LMFP, and lower-grade LFP and NMC. The path to sub-$80/kWh cells without sacrificing bankability.
More Energy Per Container
Sepion coatings are 10x thinner than ceramic coatings. More active material per cell, more energy per container and pack.
Late-Life Safety
Suppresses the plating and crossover behind self-discharge and late-life thermal events. The failure modes insurers and regulators care about.
