Study links carbon fiber microstructure to Li insertion mechanism in structural batteries

Green Car Congress

Carbon fibers have already beeen demonstrated as high-capacity Li-ion battery anodes, opening the way for their use as structural electrodes—i.e., simultaneously carrying mechanical load and storing electrical energy. The researchers studied the microstructure of different types of commercially available carbon fibers.

Volvo Car Group testing lightweight structural energy storage material applied in trunk lid and plenum cover

Green Car Congress

A composite blend of carbon fibers and polymer resin is being developed that can store and charge more energy faster than conventional batteries can. The material combines carbon fibers and a polymer resin, creating a very advanced nanomaterial, and structural supercapacitors. Click to enlarge. Click to enlarge.

Audi R18 e-tron quattro: diesel hybrid Le Mans racer with electric flywheel energy storage

Green Car Congress

On the Audi R18 e-tron quattro, kinetic energy is recovered on the front axle during the braking phase. Power from the Motor Generator Unit accelerates the carbon-fiber flywheel, which runs in a high-vacuum. After the corner is taken and the driver accelerates again, the system delivers the energy to the front axle.
