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.

MIT team devises approaches for practical carbon-nanotube-coated carbon fiber; stronger, more electrically conductive

Green Car Congress

MIT scientists demonstrated two approaches for growing CNTs on carbon fiber without degrading the fiber strength. Researchers at MIT have demonstrated two approaches for producing carbon fibers coated in carbon nanotubes without degrading the underlying fiber’s strength. Credit: ACS, Steiner et al.

Toyota introduces second-generation Mirai fuel cell electric vehicle as design and technology flagship

Green Car Congress

For 2021, Toyota has fully rebooted the Mirai, originally offered in 2016, as a premium rear-wheel drive sports-luxury fuel cell electric vehicle (FCEV) with striking design, cutting-edge technology, more engaging driving performance and a significantly longer EPA-estimated range rating.

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. Among the advantages of aluminum is that it is abundant in the earth’s crust, it is trivalent and light, and it therefore has a high capacity to store more energy than many other metals. A paper on the work is published in Nature Energy.

Viritech partners with Pininfarina on Apricale hydrogen hypercar

Green Car Congress

Pininfarina HAS re-interpreted the Apricale’s initial reference design to create a vision of the future of zero-emissions performance motoring. As the tanks have to withstand extremely high pressure (up to 700 bar or 700 times atmospheric pressure), they are very heavy, even when constructed with carbon fiber.
