Markus Zetterström to Lead Sinonus in Revolutionary Carbon Fiber Battery Technology

Markus Zetterström has taken the helm as CEO of Sinonus, a promising spinout from Chalmers University of Technology and KTH, which is part of the Chalmers Ventures portfolio. In his new role, Zetterström will steer the company towards commercializing its innovative carbon fiber technology that serves dual purposes as battery electrodes.

Sinonus has showcased its technology’s potential by successfully replacing AAA batteries in low-power lab products. The company aims to extend this technology to larger applications, such as IoT devices, drones, computers, vehicles, and even airplanes.

Carbon fiber, known for its strength and lightness, can also store energy electrochemically. Sinonus leverages this dual capability to create structural batteries that integrate energy storage into the product’s framework. This patented breakthrough marks a significant advancement in battery design and application.

For electric passenger aircraft to become feasible, a substantial weight reduction is necessary. Similarly, reducing the weight of electric vehicles (EVs) can significantly extend their driving range. Currently, the batteries in EVs account for a substantial portion of their weight. True structural batteries offer a solution by acting as both a power source and a load-bearing component. Research at Chalmers University of Technology has demonstrated that carbon fiber-based structural batteries could increase the driving range of lightweight EVs by 70 percent.

The carbon fiber technology used by Sinonus was initially developed by Oxeon, another company in the Chalmers Ventures portfolio. This technology was notably employed in the propeller blades of NASA’s Ingenuity helicopter on Mars, chosen for their exceptional light weight and thinness. The development of structural batteries represents years of dedicated research at Chalmers University, underscoring the transformative potential of this technology in various industries.
