BTRY is a Swiss cleantech startup that specializes in developing innovative solid-state lithium-ion batteries. The company’s main focus is on creating energy-dense batteries that can be charged in just one minute, addressing common limitations of traditional lithium-ion batteries. Their technology combines advanced semiconductor manufacturing techniques with sustainable practices to produce efficient, safe, and environmentally responsible energy storage solutions. BTRY’s initial market focus is on the Internet of Things (IoT) sector, particularly remote sensors, with plans to expand into consumer electronics, robotics, aerospace, and high-end medical applications.

Battery Technology

BTRY’s solid-state battery technology represents a significant advancement in energy storage systems. The design utilizes thin-film cells stacked strategically to maximize capacity while maintaining optimal energy density. This innovative approach eliminates the need for liquid electrolytes, enhancing safety and reliability. The manufacturing process incorporates high-precision semiconductor techniques that are solvent-free, reducing environmental impact.

The batteries offer several distinct advantages over conventional lithium-ion options. They achieve charging times of under one minute, maintain stability across extreme temperatures, and feature non-flammable components for improved safety. The solid-state design eliminates many of the challenges associated with traditional batteries, such as thermal runaway and capacity degradation over time.

BTRY’s technology integrates advanced materials science with precise manufacturing controls to create batteries that deliver consistent performance. The company’s focus on semiconductor-based production methods allows for scalable manufacturing while maintaining high quality and reliability standards.

Recent Projects

As of early 2025, BTRY has been actively engaged in business development initiatives, including investor roadshows in Munich to expand market reach. The company’s valuation has reached approximately $15 billion, reflecting strong market confidence in their technology and growth potential. BTRY continues to advance their solid-state battery development, focusing on applications in IoT devices and preparing for expansion into additional market segments.

Investors
