Group14 is a battery material developer specialising in silicon-carbon anodes, based in Woodinville, Washington, USA. One of the US startup’s most important investors and cooperation partners is Porsche. Following a previous funding round in the summer of 2025, during which Porsche also made an additional investment, the company has now announced the completion of another capital increase. Specifically, this involves €150 million from an unnamed investor.

What makes this particularly interesting is that, in return for this capital increase, Group14 has committed to expanding its so-called ‘SCC55’ production to Europe. The location decision has already been made: the company has selected Sagunt in Spain as the site “for its next industrial-scale manufacturing module with an initial 10 GWh capacity,” Group14 announced. By establishing a production site in Spain, the company aims to position its battery materials “directly adjacent to key European OEM supply chains.”

In the context of Sagunt, PowerCo immediately comes to mind. The Volkswagen subsidiary is known to be building one of its major battery cell factories in this city. In the future, the plant is set to become a joint venture project involving Gotion High-tech. Given its close connection to Porsche, Group14 could naturally play a role in Volkswagen’s future battery ecosystem. The unnamed investor mentioned could therefore be from the Volkswagen Group or its environment. This conclusion seems plausible but remains unconfirmed.

Regardless, Group14’s SCC55 material has, according to the developers, already “commercial traction in applications such as smartphones, drones, hypercars, and eVTOL”. In the future, it is also set to be used in EV batteries. The main feature of the new material is that it enables the use of silicon-carbon anodes instead of the usual graphite in lithium-ion batteries.

This battery ingredient is therefore set to be produced at a rate of 10 GWh per year in Spain. This would increase the short-term total production capacity to 40 GWh, according to an accompanying statement. In addition to a commercial pilot plant in Woodinville that has been operational since 2021, Group14 operates another site in Sangju, Korea (with 10 GWh) and plans to open two 10-GWh facilities in Moses Lake, Washington, USA, in 2027. For the next decade, the company aims to build production capacities to the order of “hundreds of gigawatt-hours,” according to its own statements.

Rick Luebbe, CEO and co-founder of Group14 Technologies, summarises: “To truly transform the energy economy, battery material producers must be located where the batteries are made. Our expansion into Spain reflects our vision: staying nimble, building near key customer hubs, and maintaining secure, localised supply chains.”

With the new funding commitment of €150 million (approximately $169 million), the total volume of Group14’s Series D funding round has now exceeded $665 million, according to the company. As previously reported, the startup already raised $463 million from various investors in 2025. The Series D round thus spanned nearly a year and a half.

Regarding Group14’s close ties to Germany, here is a brief digression: In 2022, Porsche first invested in the startup as part of the Series C funding round, contributing $100 million to the then $400 million capital injection. At the time, Porsche also announced that Group14 would supply battery materials to its battery subsidiary Cellforce (DE). However, Porsche announced earlier this year that it would completely shut down Cellforce.

Meanwhile: in 2023, Group14 acquired the German company Schmid Silicon, which operates a monosilane gas production facility in the Schwarze Pumpe industrial park on the border between Saxony and Brandenburg. Monosilane gas is an important precursor for Group14’s silicon battery technology.
In 2025, V4Smart – Porsche’s renamed and acquired Varta battery subsidiary – unveiled its second-generation battery cell and announced that it would use Group14’s new anode material in this cell. Shortly before, German battery cell manufacturer CustomCells had also signed a supply agreement with Group14, though the company went insolvent just a few months later.
Another important partnership for Group14 in Germany is with the chemical company BASF. Earlier this year, both companies unveiled a market-ready silicon anode solution designed to replace graphite in lithium-ion batteries. This involves combining BASF’s binder Licity 2698 X F with Group14’s advanced silicon anode material, SCC55.
