Sinonus

Sinonus is a spinout from Chalmers technical university and KTH, and part of  Chalmers Ventures portfolio. The groundbreaking technology of carbon fibers can double as battery electrodes.

The carbon fiber technology in Ccc originates from Oxeon, another of Chalmers Venture’s portfolio companies. The carbon fiber was used in the propeller blades for NASA’s Ingenuity helicopter on Mars, chosen by the engineering team due to their ultralight weight and thinness.

Carbon fiber is a strong and light construction material that can store energy electrochemically. Sinonus uses this multi-functionality to make true carbon fiber-based structural batteries that not only store energy but also become an integral part of the product’s structure. This patented innovation represents a significant step forward in streamlining batteries and how they can be used.

The development of structural batteries at Chalmers University of Technology has proceeded through many years of research, including previous discoveries involving certain types of carbon fiber. According to a study from the same university, the introduction of carbon fiber-based structural batteries could increase the driving range for lightweight EVs by 70 percent. In addition, the lower energy density of structural batteries would make them safer than standard batteries, especially as they would also not contain any volatile substances.
