Swiss deep-tech innovator BTRY recently closed a significant $5.7 million seed round. This capital fuels the industrialization of its revolutionary ultra-thin solid-state batteries. These cells redefine compact energy storage. They offer ultra-fast 1-minute charging. They operate safely up to 150°C. Intrinsic non-flammable safety is a core feature. Measuring just 0.1mm, these batteries power critical high-value applications. Targets include smart connected labels, resilient industrial sensors, and next-generation consumer electronics. The company plans large-scale roll-to-roll manufacturing. This move solidifies BTRY's position in advanced compact energy solutions, challenging traditional battery markets and enhancing device capabilities globally. This technology promises safer, smaller, and more enduring power for the connected world.
BTRY, a spin-off from Empa and ETH Zurich, stands at the forefront of battery innovation. Its recent seed round was oversubscribed. This signals immense investor confidence. Redstone VC led the investment. Bloomhaus Ventures, Linear Capital, Kickfund, and Kick Foundation joined. CustomCells founders also invested. Existing backers HTGF and Zürcher Kantonalbank renewed their commitment. This broad support underscores BTRY's market potential. It affirms the strength of its cutting-edge technology. The funding accelerates a pivotal transition. Lab-scale production shifts to industrial manufacturing.
The company's core offering is its ultra-thin solid-state battery. This technology represents a leap forward. It surpasses limitations of conventional lithium-ion cells. BTRY batteries charge in about one minute. This speed enables rapid power cycles. They operate safely at extreme temperatures. Conventional batteries fail or ignite above certain thresholds. BTRY cells function reliably up to 150°C. This robustness is critical for harsh environments. Intrinsic non-flammable safety is a hallmark. It provides peace of mind for sensitive applications. These features combine in an exceptionally thin format. Cells start at just 0.1mm thickness. They directly power wireless transmissions. No additional capacitors are needed.
BTRY leverages solid-state techniques. These methods originate from semiconductor manufacturing. This expertise creates thinner, safer, and longer-lasting batteries. The approach allows for compact, reliable, and connected devices. This technology addresses persistent power supply needs. Miniaturization and durability are paramount. BTRY specifically targets high-value applications. It avoids large-scale storage for electric vehicles or grids.
The strategic focus is clear. BTRY electrifies applications previously hindered by battery constraints. Active logistics tags benefit from thin, powerful cells. High-temperature industrial sensors gain new capabilities. MedTech applications demand safety and precision. Light consumer electronics require compact, enduring power. Next-generation solutions, like smart connected labels and wearables, are key. Traditional batteries often fail to fit or endure in these demanding use cases. BTRY offers a tailored solution. Its technology unlocks new design possibilities. It enhances performance in critical sectors.
Manufacturing innovation complements battery performance. BTRY employs a solvent-free production process. This minimizes material waste. It supports high sustainability standards. This approach reduces environmental impact. It also streamlines production efficiency. The new funds enable industrial scale-up. BTRY will establish production infrastructure. It will advance industrial processes. The company plans to secure crucial offtake agreements. These deals will integrate its batteries into future devices. Scaling to industrial roll-to-roll manufacturing is a key objective. This method promises high volume and consistent quality. It transforms world-class research into market-ready products.
BTRY's emergence marks Switzerland's strong entry into the global solid-state battery race. Asia has dominated battery manufacturing for decades. European innovation now challenges this status quo. BTRY exemplifies this shift. Its advanced materials and precision processes lead the way. The company's unique approach positions Europe as a contender. It fosters potential for global collaboration. Bringing pioneering solid-state technology to market is BTRY’s mission. It aims to set a new standard for high-performance energy storage.
The company's achievements precede this funding. BTRY has ranked among the Top100 Swiss Startups. It won Venture Kick. It participated in Venture Leaders. These accolades confirm its trajectory. They validate its entrepreneurial drive. The 14-person team combines deep battery expertise. They possess industrial scale-up experience. Strong business acumen guides their path. This blend of talent drives BTRY's success.
BTRY's solid-state battery technology is poised for broad impact. It promises to power a new generation of devices. These devices will be smaller, safer, and more connected. They will operate in more challenging environments. BTRY’s commitment to innovation and sustainability defines its vision. The future of compact energy storage looks brighter. This Swiss deep-tech firm leads the charge. Its ultra-thin cells will redefine power. They will enable progress across numerous industries. The journey from research to industrial scale is accelerating. BTRY is ready for global markets.
