BTRY receives CHF 4.6 million for ultra-thin solid-state batteries
The battery startup BTRY has raised CHF 4.6 million in an oversubscribed seed round. The financing will be used to industrialize ultra-thin solid-state batteries, which are characterized by fast charging, high temperature stability and non-flammability.
Investors show confidence in technology and market potential
The round was led by Redstone VC, supported by Bloomhaus Ventures, Linear Capital, Kickfund, Kick Foundation and the CustomCells founders. Existing investors such as HTGF and Zürcher Kantonalbank also participated.
The financing confirms the confidence of experienced deep-tech and industrial investors in BTRY.
Dr. Moritz Futscher, CEO BTRY
From research to series production
BTRY relies on diamond-based solid-state batteries that work at room temperature and can be charged and discharged in just 0.1 mm thickness in one minute. This opens up new possibilities for IoT sensors, wearables, medical technology and other high-tech applications. Production takes place on an industrial roll-to-roll production line without toxic solvents.
BTRY's batteries combine miniaturization, performance and safety and set new standards in European battery manufacturing. The start-up wants to conclude supply agreements with pilot customers and further expand its production infrastructure. The startup had already secured a pre-seed round of CHF 900,000 at the beginning of 2024.
