CAP-XX Secures Strategic Design Win with Multinational Conglomerate

CAP-XX Limited (LSE: CPX), a global leader in supercapacitor technology, is pleased to announce a design win with a major Asian-based multinational conglomerate and provider of advanced audio solutions. This underscores CAP-XX's continued innovation and expanding presence in high-growth technology sectors.

The engagement, currently under commercial confidentiality, will involve the integration of CAP-XX's supercapacitors into the customer's next-generation headphone platform. The new solution will enhance the device's battery system by improving overall power efficiency and delivering superior performance across a wide temperature range from -25°C to +65°C.

Having been qualified as a direct supplier, CAP-XX is well positioned for potential broader deployment across future product lines. The new headphone platform is scheduled for launch in October 2025.

This design win strengthens CAP-XX's role in global supply chains and reflects the rising demand for advanced energy storage solutions in consumer electronics.

Lars Stegmann, CEO of CAP-XX, commented: "This design win is a strong endorsement of our technology and validates the value CAP-XX brings to next-generation consumer electronics. As devices become more compact and power-hungry, efficient energy storage becomes mission-critical. We are proud to support our customer's innovation journey and excited about the broader opportunities this relationship may unlock."
