Battery materials, engineered in Grenoble
More energy in your battery.
Enwires builds silicon-graphite composites that raise the energy density of lithium-ion batteries — without changing how they're manufactured.
Who we are
Enwires is a team of around ten people, working alongside experts from the battery industry. We focus on one problem: how far a graphite-based anode can be pushed before it needs to be replaced.
Lithium-ion batteries are one of the most widely used technologies of modern life, and one of the most constrained. We build materials that extend what's already in production, rather than asking manufacturers to start over.
What we offer
-
Higher energy density
SiBoost combines graphite's conductivity with silicon's capacity to store lithium, so cells can hold more energy at the same size.
-
Drop-in compatibility
Our process adapts to graphite grades already used across the industry, including material that's currently under-used because of its characteristics.
-
Smaller or lighter cells
The same performance in less volume and weight — or more performance in the footprint manufacturers already have.
Built at pilot scale
SiBoost is produced on real production equipment, not lab glassware — so what works in testing is what ships.
From powder to particle
Every batch is verified under electron microscopy before it leaves the lab.
