Floatech, a startup specialized in the development of 100% silicon anodes for next-generation batteries, has closed a €1 million funding round. The round was led by Grow Venture Partners and included participation from existing investors, such as Big Sur Ventures, Suma Capital, and CDTI Innovación through its SICC Innvierte, as well as the addition of Banco Sabadell, through BStartup, as a new investor. 

The funding will allow Floatech to accelerate the commercialization of its flagship product, Si⋮Coil®, a 100% silicon anode for applications in the electric mobility and consumer electronics sectors. It will also be used to industrialize the production process for scaling and to launch a new product for solid-state and lithium-metal batteries. 

“This round gives us the boost we need to bring our technology to market under industrial conditions. We are very grateful for the continued trust of our partners and especially excited about Banco Sabadell’s entry at this strategic stage,” said Fernando Celaya, CEO of Floatech. 

FLOATECH has achieved exceptional milestones in the development of silicon anodes for batteries, advancing from TRL 6 to commercial stage in just 14 months. Its proprietary technology is the only one on the market compatible with all electrolyte types, maintaining structural integrity and charge cycles. It also increases energy storage capacity tenfold compared to traditional carbon-based systems, while halving the cost of conventional graphite anodes. These advances position FLOATECH at the forefront of the next generation of high-performance batteries, key for segments such as Automotive, Consumer Electronics, and civil and defense Aero-mobility. 

Floatech develops and manufactures pure silicon anodes, a more efficient, cleaner, and longer-lasting alternative to conventional graphite anodes. Its technology enables batteries with ranges exceeding 1,000 km and recharging times of under 10 minutes, opening new possibilities in sectors such as electric mobility, light aviation, and advanced electronics. 

Headquartered in Getafe (Madrid) and recently installed in the TecnoGetafe Technology Park, Floatech already operates a plant capable of producing up to 1 MW, launched in September 2024. The company holds strong intellectual property through a patented manufacturing process and has been recognized with the Seal of Excellence from the European Innovation Council (EIC), as a high-potential startup by Bpifrance, and by Caixa Emprende XXI for its innovative and disruptive nature. 

“Floatech represents a very promising combination of industrial innovation, technical talent, and market vision. At BStartup, we are committed to technologies that drive the energy transition and generate real impact,” stated Laurent Arens, Director of BStartup10. 

The demand for sustainable storage solutions is growing exponentially in Europe, driven by decarbonization goals and the electrification of transport. Floatech is positioning itself as an emerging player within the European energy innovation ecosystem and as a technological benchmark in the industrial development of advanced batteries.
