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

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones. Background.

KAUST uses laser pulses to boost performance of MXene electrode

Green Car Congress

The researchers hope that this strategy could help to engineer an improved anode material in next-generation batteries. Graphite contains flat layers of carbon atoms, and during battery charging, lithium atoms are stored between these layers in a process called intercalation. Resources Bayhan, Z., El-Demellawi, J.

Report: VW invests in novel energy storage company QuantumScape and its solid-state “All Electron Battery”

Green Car Congress

Volkswagen executives have been hinting for awhile now about taking a different approach to high-energy-density electrical storage for long-range electric vehicles than the more “conventional” next-generation Li-ion or Li-metal battery pathways. conventional capacitors). Corresponding gravimetric densities at top.

U of Illinois team models capabilities of hybrid-electric propulsion systems for general aviation aircraft

Green Car Congress

Researchers at the University of Illinois at Urbana-Champaign have utilized a series of simulations to model the performance of twin-engine hybrid-electric general-aviation propulsion systems. The same sensitivities were studied with a series hybrid-electric drivetrain. Their paper appears in the Journal of Aircraft.

Thermal Energy Storage Is No Longer Just Hot Air

Cars That Think

The shipping containers, which house a Frankenstein-like assortment of machine parts—motors repurposed from Volvo truck engines, giant tanks of compressed air, huge silos of piping hot sand—are produced by a company called Cheesecake Energy. Recent years have seen the construction of large lithium-ion battery farms that do just that.

Bus maker Alexander Dennis to fit GKN Gyrodrive flywheel hybrid systems to 250 buses; partners on international development

Green Car Congress

Instead of a battery, the Gyrodrive system uses a magnetically loaded high-speed carbon-fiber flywheel to store the energy generated by a bus as it slows down to stop. The electric flywheel technology is particularly suited to applications that demand high symmetric power transmission at continuous cyclic duty cycle.
