Scientists have found carbon fibre that stores electricity

Because science!

Batteries – heavy, cumbersome, boring. Carbon fibre – light, sexy, futuristic. Now science has kind of combined the two and found that the material is capable of storing electricity. 

Research by Chalmers University of Technology in Sweden has shown carbon fibre can work as battery electrodes and store energy directly, meaning it can become part of the energy system and reduce the need for big batteries. Or put simply LESS HEAVY MORE SPEED.

Tests found that fibres with smaller crystals – but less stiffness – had a better ability to operate as electrodes in a lithium-ion battery. Fibres that were slightly stiffer than steel worked much better than those twice as rigid as steel. 

Leif Asp, Professor of Material and Computational Mechanics at the university, explained: “A car body would be not simply a load-bearing element, but also act as a battery. It will also be possible to use the carbon fibre for other purposes such as harvesting kinetic energy, for sensors or for conductors of both energy and data. If all these functions were part of a car or aircraft body, this could reduce the weight by up to 50 per cent.”

The science could be expanded into aviation, where passenger aeroplanes will need to lose significant weight before any plans of electric power could be considered. 

“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,” says Asp.

So… yep. We’re not sure how it really works but it sounds cool. Because science. Mitochondria is the powerhouse of the cell and all that.
