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.

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. In this €3.4-million million (US$4.7-million)

Chalmers team develops structural battery that performs 10x better than previous versions

Green Car Congress

It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. The structural battery uses carbon fiber as a negative electrode, and a lithium iron phosphate-coated aluminum foil as the positive electrode. GPa, and tensile strength exceeding 300?MPa.

New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism. 1 , almost 3 times higher than the commercially available graphite anode. In this process the active material is reversibly reduced into metallic nanoclusters embedded in a Li 2 O matrix …. —Maroni et al.
