Spain’s Floatech secures €1M to supercharge silicon anode battery tech

Getafe-based Floatech, a company specialised in developing silicon anodes for lithium-ion batteries, has completed a €1M funding round.

The round includes contributions from Grow Venture Partners, Big Sur Ventures, Suma Capital, CDTI Innvierte, and BStartup Banco Sabadell. This step supports Floatech’s push to bring its silicon anode battery technology, Si⋮Coil, to the market.

Capital utilisation

Floatech plans to use the capital to expand the reach of its Si⋮Coil battery platform. The focus will be on scaling production processes, increasing battery output, and strengthening market readiness. 

The funding will also support efforts to validate the technology in various industrial settings.

Floatech CEO, Fernando Celaya, mentions in a statement, “This round gives us the necessary impetus to bring our technology to market in industrial conditions.”

Brief about Floatech

Floatech focuses on lithium-ion battery components, with a core technology centred on silicon anodes. These anodes are produced through a process that excludes solvents and polymers. The method enables manufacturing at scale, lowers emissions, and aligns with cost reduction goals.

The company is based in Getafe and operates a 1 MWh demonstration facility. It is a spin-off of the IMDEA Materials Institute.

Floatech’s approach targets multiple sectors, including electric transport, personal electronics, and light aviation. The company seeks to improve battery charging time, range, and environmental footprint.

Recently, Floatech announced that it has successfully concluded its role in the E-BOOST project, a European Union–funded initiative focused on advancing sustainable mobility. Key outcomes include a conceptual design for silane production, validation of silane use in nano-silicon anodes, and a strategic framework for compliant sourcing.
