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. A slight reduction in stiffness is not a problem for many applications such as cars.

Swedish researchers explore use of carbon fiber as active electrode in structural battery for electric vehicles

Green Car Congress

Woven carbon fiber can act as an electrode for lithium ion batteries. Researchers in Sweden are exploring the use of carbon fiber as an active electrode in a multifunctional structural Li-ion battery in an electric car; i.e., electrical storage is incorporated into the body of the car.

New high-performance foldable cathode for Li-S batteries based on 3D activated carbon fiber matrix

Green Car Congress

A team at Sun Yat-sen University in China has developed new high-performance, stable cathode for Li-S batteries consisting of a 3D activated carbon fiber matrix (ACFC) and sulfur. The electrical conductivity of the cathode is therefore not satisfied. An open access paper on their work is published in Scientific Reports.

Carbon Cryogels and Carbon Fiber Paper as Approaches for Silicon Anodes for Li-ion Batteries

Green Car Congress

The two silicon-carbon composite materials are formed via the dispersion of silicon in a resorcinol-formaldehyde (RF) gel followed by pyrolysis and possess either microsphere or nanofoam morphologies. The carbon matrix will also prevent direct electrolyte contact with the silicon. Woodworth, Richard Baldwin and William R.

DOE awarding $19.4M to 22 advanced vehicle technologies projects; Mercedes-Benz, GM Li-S battery projects

Green Car Congress

Among the awardees are Mercedes-Benz Research & Development North America and GM, with separate projects on Li-sulfur batteries, as two of the fifteen Phase 1 “Battery Seedling” Projects. These projects enable smaller, safer, lighter weight, and less expensive battery packs that ultimately will make electric vehicles more affordable.
