About E-magy

E-magy is an advanced materials company addressing the demand for higher-performance batteries in the electric vehicle (EV) market. The firm specializes in producing nano-porous silicon, an anode material that increases the energy density of lithium-ion batteries by up to 40% compared to conventional graphite anodes. The core of its technology is a proprietary, low-cost process for manufacturing structured silicon particles. These particles feature nanoscale pores that accommodate the natural swelling of silicon during charging cycles, a technical problem that has historically limited silicon's commercial viability. This innovation prevents material degradation and allows for the creation of silicon-dominant anodes, leading to batteries that offer extended range and faster charging capabilities. A key commercial advantage of E-magy's product is its compatibility with existing lithium-ion battery manufacturing lines, making it a low-risk, 'drop-in' solution for gigafactories. The technology has been validated by the German research institute ZSW, which confirmed near-zero swelling (less than 1%) in pouch cells using E-magy's silicon after 100 cycles. Founded in the Netherlands, the company has been developing its technology since 2013 and operates a pilot production facility near Amsterdam with an annual capacity of 25 tons, which is scalable to 300 tons per line. The company is led by CEO Casper Peeters, who joined in 2020 and previously founded and led Xsens, and CTO Axel Schönecker. E-magy operates a B2B model, supplying its material to automotive and battery manufacturers. The company has secured significant funding to scale its operations. This includes a •5 million round in 2021 and a Series A round in 2023 that raised •15 million (~$16 million), led by industrial company Hydro, alongside a •5.5 million subsidy from the Dutch National Growth Fund. E-magy actively participates in European battery research consortia, such as TEESMAT, to advance battery technology and material characterization.
