Dutch battery startup E-magy has secured 15 million euros in series A funding, along with 5.5 million euros in Nxtgen Hightech subsidy. The money will be used to prepare for industrial-scale production of nanoporous silicon-anode material.

Silicon has long been recognized as a promising alternative anode material for lithium-ion batteries, given its ability to accommodate ten times more lithium than commonly used graphite. However, silicon anodes typically swell and break when charged and discharged.

E-magy has developed a high-throughput casting process to manufacture nanoporous silicon that contains the swelling. This material delivers 40 percent higher energy density and enables faster charging, the company based in Broek op Langedijk claims. Furthermore, it says that its technology is easily scalable.
