Group14 Technologies Secures $463M to Expand SCC55 Silicon Battery Material Production

Group14 Doubles Down on SCC55 Silicon Battery Material Expansion

Group14 Technologies has closed a $463 million Series D funding round to boost global production of its SCC55 silicon battery material. The round was led by SK Inc., with strong support from investors like Porsche Investments, Microsoft Climate Innovation Fund, ATL, OMERS, and Decarbonization Partners. With this round, Group14 has raised over $1 billion in equity. This strengthens its position as a key player in advanced battery materials.

The new capital will scale SCC55 production in the U.S. and South Korea. This will help meet fast-growing global demand for high-performance battery materials. SCC55 is a proprietary silicon-carbon composite developed by Group14. It increases energy density and reduces charge times in next-generation lithium-ion batteries. These benefits make it ideal for EVs and consumer electronics. Group14 says over 100 customers worldwide have already begun receiving SCC55.

Group14 Gains Full Ownership of BAM-3 Factory in South Korea

In tandem with the funding news, Group14 has acquired full ownership of BAM-3, its third battery active materials (BAM) facility, previously operated as a joint venture with SK Inc. Located in Sangju, South Korea, BAM-3 began delivering SCC55 at commercial EV scale in September 2024. This strategic facility offers 10 GWh of production capacity and is situated in close proximity to Asia’s leading battery manufacturers.

Group14’s other BAM facilities are based in Washington state, while the company is also expanding into Europe. It is currently building a silane gas plant in Germany to supply critical precursors for silicon-enhanced batteries. This global infrastructure positions Group14 to support battery makers across North America, Europe, and Asia, solidifying its foothold in the growing energy storage supply chain.

SuperMetalPrice Commentary:

Group14’s bold expansion of its SCC55 production and complete acquisition of BAM-3 in South Korea demonstrate strategic foresight. By strengthening control over its supply chain and securing significant funding, the company is poised to meet rising demand for silicon-based battery materials. This move reflects a broader shift toward next-generation anode materials, as battery makers seek higher energy density and faster charging performance. With facilities in the U.S., Korea, and Germany, Group14 is emerging as a critical enabler of the global EV and storage revolution.
