Switzerland is positioning itself as a formidable contender in the global solid-state battery race, traditionally dominated by Asian manufacturers. The latest move comes from Zurich-based BTRY AG, which has secured €4.9 million in seed funding led by Redstone VC. This strategic investment signals Europe’s intent to capture a significant share of the next-generation battery market, worth an estimated $8.5 billion by 2030.
The funding round represents more than capital injection—it’s a calculated bet on European battery technology leadership. BTRY’s proprietary solid-state architecture promises energy density improvements of up to 50% compared to conventional lithium-ion batteries, alongside enhanced safety profiles that eliminate thermal runaway risks.
Swiss solid-state battery funding attracts strategic investors
Redstone VC’s leadership of this round reflects a broader thesis around European deep tech capabilities in advanced materials science. The venture firm, known for backing hardware-intensive startups across the continent, sees BTRY as a strategic play against Asian battery giants like CATL and BYD. “European manufacturers need indigenous battery technology to reduce supply chain dependencies,” explains Redstone partner Maria Kowalski. “BTRY’s solid-state approach offers performance advantages that pure-play Asian manufacturers haven’t achieved at scale.”
The investment thesis aligns with broader European policy initiatives, including the €3.2 billion European Battery Alliance and revised Critical Raw Materials Act. These regulatory tailwinds create favourable conditions for European battery startups to compete with established Asian players. Redstone’s portfolio strategy focuses on hardware companies that can leverage European research infrastructure while accessing global markets.
Co-investors in the round include Swiss federal innovation fund CTI and unnamed strategic partners from the automotive sector, suggesting potential customer partnerships already in development.
Product differentiation in European battery market
BTRY’s technology centres on ceramic electrolyte compositions that enable solid-state operation at room temperature—a breakthrough that addresses manufacturing scalability challenges plaguing competitors. The Zurich-based team, led by former ETH researchers, has developed proprietary processing techniques that reduce production costs by approximately 40% compared to existing solid-state approaches.
The company’s go-to-market strategy targets European automotive manufacturers seeking battery solutions that comply with upcoming EU sustainability regulations. “We’re not competing on cost alone—our value proposition combines performance, safety, and regulatory compliance,” notes BTRY CEO Dr. Andreas Weber. “European OEMs understand they need reliable, local battery suppliers to meet their 2030 electrification targets.”
Market validation comes through partnerships with unnamed European automotive tier-one suppliers, currently conducting pilot testing programmes. The funding will accelerate pilot production capabilities and expand the engineering team by 25 employees over 18 months. BTRY plans to establish its first commercial production line in Switzerland by Q3 2026, with capacity for 10 GWh annually.
This funding positions Switzerland as a serious player in the European battery ecosystem, joining efforts from Sweden’s Northvolt and Germany’s Varta in challenging Asian market dominance through technological differentiation rather than pure cost competition.
