Better
performance

Our specialty silicon ensures higher energy density and faster charging; it solves the swelling problem, making silicon-dominant anodes (>80% silicon) a reality.

Highly
compatible

This is the low-cost solution compatible with existing production lines that the EV industry needs – as currently verified by R&D managers of more than a dozen leading automotive and battery manufacturer brands.

Scalable
production

Our nano-porous silicon is now in production for industrial application in our in-house facility, ready to scale up.

Pores in the silicon particles

Higher energy
density

E-magy creates a revolutionary silicon dominant anode material for lithium-ion batteries that delivers 40% higher energy density (in Wh/kg).

Negligible anode
expansion

Tests performed in cooperation with renowned German institute ZSW have shown a negligible pouch cell thickness variation of <5% after 100 cycles, with an 80% weight silicon anode.

Low carbon
footprint

We use low-cost upgraded metallurgical grade silicon that is abundantly available and environmentally benign. Our efficient casting process ensures a low carbon footprint.

Large gains for consumers

The value our nano-porous silicon provides to consumers does not end with electric vehicles. A host of products see massive advantages.
Higher energy density in batteries leads to lower weight and size of battery packs. This not only translates to more attractive EVs for the masses, but also to longer-lasting smartphones, lighter wearables and thinner laptops.

Inhouse- production
cost efficient and scalable

Our nano-porous silicon is produced in our own, fully operational production facility near Amsterdam. The machinery covers 1200 square meters and operates at an industrial scale, can run 24/7 and is capable of producing up to 25 tons a year.

Efficient

We use an efficient silicon crystallization process with industry-standard post-processing steps.

Compatible

Our nano-porous silicon is compatible with existing lithium-ion battery manufacturing processes and installed factory equipment. This makes it a low risk and easy to adopt solution.

Scalable

The facility is capable of manufacturing 25 tons of nano-porous silicon per year. We have designed the process to be easily scalable, with a capacity per line of 300 tons per year.
