6K Lands $51 M for Advanced Battery Material Dev

Budget reactions

Massachusetts-based 6K, which produces sustainable advanced materials for energy storage and additive manufacturing powders, has closed a $51M Series C financing round.

With this investment, 6K will complete its Battery Development Center of Excellence, adding 33,000 sq ft of state-of-the-art product development space and doubling its 6K Energy team, said the firm.

Funding will also enable a tripling of production capacity for 3D metal powders at its 6K Additive division, increase the portfolio of powder product offerings, and expand its commercial sales activities globally, added the company.

The financing round was led by Volta Energy Technologies, joined by new investors Catalus Capital and S Cap/Prithvi Ventures, and existing investors Anzu Partners, Launch Capital, Material Impact, and RKS Ventures.

“This round of capital is a validation of 6K’s model to replace wasteful legacy production technologies with the UniMelt® platform, enter scaled production, meet customer needs, move toward profitability, and transform industries,” commented Aaron Bent, CEO of 6K.

“We are joined by world-class investors who are aligned with our vision to transform the way performance materials are produced. And in doing so, we are teaming to solve critical needs of the US and the planet, addressing climate change, supply chain security, and reducing the demand on our fragile and limited resources.”

6K states that its mission is to provide a solution for global decarbonization in the production of performance materials, critical to manufacturing and production infrastructure. The company’s UniMelt plasma production system is a high volume production process, producing advanced performance materials in as little as two seconds versus two-three days. The system uses a lower-cost and smaller footprint production technology.

The UniMelt production process can produce products as varied as batteries materials for electric vehicles, semiconductor materials, 3D printing powders, phosphors, advanced ceramics, and electronic materials, states the firm.

6K will be using the proceeds of the financing to expand product development and commercial activities across its multiple divisions:

• 6K ADDITIVE: 6K claims to be the only premium metal powder supplier for 3D printing produced from sustainable sources, targeting the commercial space, medical, and industrial sectors. Following the commissioning of its 45-acre ISO9001 24/7 state-of-the-art powder production operations in 2020, 6K will now expand production with an additional 600 tons/year and set up sales and distribution in Europe and Asia.
• 6K ENERGY: 6K has announced its intent to invest $25M over 24 months in its Battery Development Center of Excellence, enabling unique business models with partners for rapid product development and deployment. The Center will be fully capable of pilot production with UniMelt capacity equivalent of 400 MWh, says the firm. 6K is currently sampling customers, and developing products across NMC cathode, LFP, silicon-dominant anode, lithium, solid-state electrolyte, and recycled cathode materials.
• 6K FUTURE MATERIALS: 6K, in response to demand from companies across the performance materials spectrum, will invest in the identification and development of performance and electronic materials that can be produced cost-effectively and sustainably with its UniMelt plasma production system. The firm has established an advanced R&D team for the development of performance materials including those for applications ranging from semiconductors to electronic packaging to bio-ceramics to name just a few.
