GDI, a researcher and manufacturer of 100% silicon anode technology for lithium-ion batteries, has completed a Series A funding round and begun pilot production of a 100% silicon Li-ion battery anode in Eindhoven, the Netherlands.
GDI’s technology uses a 100% silicon anode design, which allows for >30% greater energy density for advanced Li-ion batteries, and for safe and reliable fast charging from 10-75% in 15 minutes.
It said the $13.3 million Series A funding, led by EIT InnoEnergy and Helios Climate Ventures, adds to $3 million in government funding from the US Army Research Labs, a Phase II SBIR from the US Department of Energy, and the US Defense Logistics Agency.
GDI has established European pilot production in Eindhoven, with 300kWh production capacity expected to be online by the end of 2022.
The new funding and planned strategic partnerships means GDI expects to scale production to over 100MWh by Q1 2024.
It said silicon is unique in that it can store vast amounts of Li-ions at rapid speeds, enabling sub-15-minute charging speeds and EVs with over 500 miles in range.
GDI has tested multi-layered pouch cells that can charge from 10-75% state of charge in 15 minutes over 600 times in a row without plating lithium or failing, without added compression or added lithium as competitors require.
