Charging expectations are rising. Battery architectures are getting thinner. Performance margins are shrinking.
Power is a structurally engineered separator that enables more durable fast charging, greater energy density, and more efficient system design — without increasing material mass.
Faster Charging
Designed to support repeatable high-rate charging under demanding conditions.
Greater Energy Density
A thinner architecture that enables smarter pack design — a drop-in gain of 1-5% Wh/L and Wh/kg.
Lower Material Intensity
10x thinner and 20x lighter than ceramic coatings, per m2.
Value Creating for All Chemistries
Drop-in compatible with NMC, LFP, manganese-rich (LMFP, LMR, LNMO, LMO), silicon, semi-solid, and lithium-metal systems.
Improved Safety & Durability
Reduced self-discharge controlling metal cross-talk.
Designed for Performance-Led Systems
Electric Vehicles
Where fast charge and range define competitiveness.
- Higher-rate charging performance
- Reduced material mass per cell
- Greater packaging flexibility
- Compatibility across advanced chemistries
AI Infrastructure
Where high-output systems demand stability at scale.
- Improved durability in demanding environments
- Thermally stable under high-load operation
- Lightweight and high-power
Consumer Electronics
Where thinness and energy density matter most.
- Reduced separator thickness
