Making impossible electrification possible
We develop cutting-edge materials for safe and high-performance lithium-sulfur batteries. Based on more than a decade of research.
Disruption where weight is a limiting factor
Replacing battery materials in hard-to-abate applications where weight is a critical constraint, and enabling new product categories that were previously impossible:

Materials that contain polysulfides and unlock battery performance
Sulfur-based cathode material
For high-performance Li-S batteries. Based on our expertise in cutting edge nanomaterials.
Separator
For demanding li-ion applications, safe and long-lasting Li-S batteries and other new chemistries.
Five pillars behind our wholistic approach to Li-S batteries
Long lifetime
Thousands of cycles with polysulfide control.
High power
Great rate capabilities up to 8x conventional li-ion
Lightweight
Up to 5x higher energy density than conventional li-ion batteries.
Safety
Engineered separator and non-oxygen-releasing cathode lower risk at every level.
Low cost
Replacing critical materials like nickel and cobalt with abundant sulfur.
