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

Green Car Congress

Researchers from Chalmers University of Technology, in collaboration with KTH Royal Institute of Technology in Stockholm, have produced a structural battery that performs ten times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material.

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)

Making EV batteries the body: Researchers claim a tech breakthrough

Green Car Reports

Researchers at the Chalmers University of Technology claim to have produced a working "structural battery" that can both hold a charge and, as the name says, act as part of a vehicle's structure. The battery is made from carbon fiber, which is already.

Cornell team develops aluminum-anode batteries with up to 10,000 cycles

Green Car Congress

This magnified image shows aluminum deposited on carbon fibers in a battery electrode. It reacts chemically with the glass fiber separator, which physically divides the anode and the cathode, causing the battery to short circuit and fail. A paper on the work is published in Nature Energy. —Jingxu Zheng.
