GM researchers demonstrate hierarchical electrode architectures for high energy lithium-chalcogen rechargeable batteries

Green Car Congress

lithium-sulfur (Li-S) and lithium selenium (Li-Se) systems— are promising candidates for high energy electrical storage solution. A corresponding chalcogen cathode structure, which is composed of a chalcogen element (S or Se), a conductive framework, and a polymer binder, is well-accepted for most studies.

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.
