Group14 Technologies, a US-based manufacturer of silicon battery materials, has secured €150 million (approximately $169 million) in a Series D equity extension to expand its global manufacturing operations and establish a new production facility in Spain.
The investment came from a new investor whose identity was not disclosed. According to the company’s October 29, 2026 announcement, the financing brings its Series D round to more than $665 million.
The funding will support Group14’s manufacturing expansion across North America, Asia and Europe, with a focus on increasing production of its silicon-carbon battery material, SCC55.
Founded in 2015 by Rick Luebbe and Dr. Rick Costantino, Group14 Technologies is headquartered in Woodinville, Washington. Luebbe serves as CEO, while Costantino serves as CTO. The company develops silicon-carbon anode materials designed to replace conventional graphite in lithium-ion batteries, supporting higher energy density and faster charging.
A central part of the expansion is the planned Battery Active Materials facility, BAM-4, in Sagunto, Spain. The facility will have an initial production capacity equivalent to 10 gigawatt-hours (GWh) of battery capacity, establishing an industrial-scale manufacturing site for SCC55 in Europe.
The Spanish facility is expected to increase Group14’s planned near-term manufacturing capacity to 40 GWh across three regions.
The company’s existing and planned manufacturing network includes:
- BAM-1, Woodinville, United States: A commercial-pilot facility operating since 2021.
- BAM-3, Sangju, South Korea: An operational 10 GWh manufacturing module undergoing production scaling.
- BAM-2, Moses Lake, United States: Two planned production modules with a combined capacity of 20 GWh, expected to begin production in 2027.
- BAM-4, Sagunto, Spain: A planned industrial-scale facility with an initial 10 GWh capacity.
Group14 said its Woodinville facility has supplied SCC55 to more than 150 customers. Its technology is used in applications including consumer electronics, electric mobility and electric aviation.
The company also reported a global intellectual property portfolio of more than 200 patents covering its battery materials and manufacturing processes.
The additional capital will support production capacity expansion to serve manufacturers in the automotive, consumer electronics, data centre, aerospace and defence industries.
