Carbon Fiber can Store Energy in the Body of a Vehicle

The researchers' vision is of vehicles where a large part of the car-body or aeroplane-fuselage consists of structural lithium ion batteries. Multi-functional carbon fibre can work as battery electrodes and load-bearing material consecutively. The researchers work with structural lithium ion batteries where the negative electrodes are made of carbon fiber and the positive electrodes are made of cathode-coated carbon fiber. In the picture, the battery is charged, which means the negative electrode is filled with positively charged lithium ions.

A study led by Chalmers University of Technology, Sweden, has shown that carbon fibres can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fibre becomes part of the energy system. The use of this type of multifunctional material
