Structural batteries are strong enough to build things from and can store energy. New advances are paving the way for drones, computers, cars, and airplanes that can store electricity in the construction itself. Researchers at Chalmers University of Technology in Gothenburg have long been developing this dual-function carbon fiber material.
' For the first time, researchers can make a product lighter by replacing the battery and construction material with this new solution. Lighter products mean lower energy consumption. Products that could benefit include drones, handheld tools, laptops, and mobile phones.
In the long term, the vehicle, aviation, and space industries could also gain. Leif Asp and his colleagues recently presented the technology at the World Economic Forum in Davos. The World Economic Forum has listed structural batteries as the most promising future technology, with osmotic power systems as number two and advanced nuclear power as number three.
' Currently, Chalmers researchers' structural batteries can store energy corresponding to about 80% of regular lithium batteries. , how quickly energy can be converted for use. Researchers in China, Australia, and Sweden, among others, are working to improve the technology.
Several challenges remain, including stiff competition and the need for high performance to attract investment. The specific timeline for commercial adoption and exact cost implications are unclear.
