Zurich, February 12, 2025 – The Swiss battery startup BTRY today announced the launch of its seed fundraising to enable the development of market-ready products and the scaling of production. The company addresses the need for small and high-performing energy storage solutions in IoT, MedTech, and Consumer Electronics. In these sectors, the total addressable market for specialized batteries is projected to be approximately $70 billion by 2030, beyond the mass market of commodity, EV, and grid energy storage.

“This is the battery moment: everything is becoming smart and needs a reliable remote power source. Our technology to produce thin and high-performing batteries is now ready for commercialization.” – Moritz Futscher, Co-Founder and CEO of BTRY

The battery moment for smart and remote applications

The demand for small, high-performance energy storage for smart and remote applications is surging across industries. Small active devices require integrated power solutions with custom designs, rapid charging capabilities, and high-temperature stability—qualities that existing battery technologies lack.

BTRY is conducting proofs of concept for IoT applications like secure authentication and logistics tracking via active smart cards and labels, where an integrated and ultra-thin power solution is needed. Other areas include small integrated devices in MedTech and wearable Consumer Electronics. The next phase of development will focus on refining the prototypes into market-ready products.

Scaling battery production in Europe

The core of BTRY’s innovation is a novel vacuum solid-state production process that stacks thin layers into batteries of any form. This breakthrough is based on established technology that enables efficient, highly scalable, and environmentally sustainable battery manufacturing. Unlike traditional Li-ion battery production, BTRY’s platform technology is designed to power multiple applications with the same process and machinery.

The key advantages of BTRY’s proprietary production technology are:

  • Simplified production process – Reduces the number of manufacturing steps by 60% compared to conventional Li-ion battery production.
  • Off-the-shelf equipment – Avoids reliance on expensive and complex proprietary machinery, making industrial scaling easier.
  • Sustainability – Reduces environmental footprint by applying low-impact materials, solvent-free production, and recyclable-by-design principles.

BTRY has successfully produced its first custom battery prototypes in a laboratory environment and tested production on a larger scale. The next milestone is to set up pilot facilities, with the goal of establishing full-scale manufacturing in Europe.

BTRY is ready for the next phase: New presentation showcases BTRY’s potential

BTRY achieved operational readiness and staffed its core and advisory teams in R&D, production, and business development. Its newly established headquarters are near Empa’s cutting-edge battery research facilities and embedded in the Zurich technology ecosystem. In addition, BTRY has launched a new website and corporate video, providing stakeholders with a comprehensive overview of its vision, products, and technology.

“BTRY’s founders have done an exceptional job in assembling a strong team and gaining initial market traction. What truly differentiates BTRY is its innovative production approach, which not only overcomes existing technical barriers in solid-state battery manufacturing but also unlocks new opportunities for scalable, industrial production.” – Timo Bertsch, Hightech Gründerfonds (Investor in BTRY)


With these developments in place, BTRY is poised to ignite the next stage of its journey: securing seed funding, finalizing market-ready products, and preparing for European battery production at scale. Investors with a background in industrial scaling who want to be part of the future of sustainable, high-performance energy storage are encouraged to engage with BTRY as it tackles commercialization.
