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

A Lithium-Sulfur Battery Evolution

The hot-press procedure, developed at Drexel, melts sulfur into the nanofiber mats in a slightly pressurized, 140-degree Celsius environment -- eliminating the need for time-consuming processing that uses a mix of toxic chemicals, while improving the cathode's ability to hold a charge after long periods of use.

In late July of 2008 a British solar plane set an unofficial flight-endurance record by remaining aloft for more than three days straight. Lithium-sulfur batteries emerged as one of the great technological advances that enabled the flight -powering the plane overnight with efficiency unmatched by the top batteries
