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

Green Car Congress

Friend Family Distinguished Professor of Engineering, have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. Now, they have employed a different approach for incorporating aluminum, resulting in rechargeable batteries that offer up to 10,000 error-free cycles.

Stanford team develops new simple approach for viable Li-metal anodes for advanced batteries

Green Car Congress

Lithium-metal anodes are favored for use in next-generation rechargeable Li-air or Li-sulfur batteries due to a tenfold higher theoretical specific capacity than graphite (3,860 mAh/g vs. 372 mAh/g); light weight and lowest anode potential. The Li flowed easily into the scaffold and occupied the empty spaces between each single fiber.

Ferrari’s Plug-in Hybrid One-Ups the Combustion Engine

Cars That Think

Spinning at up to 25,000 rpm, two permanent-magnet motors independently power the front wheels, or regenerate energy from braking to recharge the batteries. That front-drive mode gets the car a green light in cities like London and Rome as they begin to bar polluting cars from their downtown areas. And don’t forget sound.

GM Unveils EN-V Concepts for Future Urban Mobility

Green Car Congress

Dynamic stabilization technology empowers EN-V, giving it the unique ability to carry two passengers and light cargo in a footprint that’s about a third of a traditional vehicle. Recharging can occur from a conventional wall outlet using standard household power, allowing EN-V to travel at least 40 kilometers (25 miles) on a single charge.

Microporous polymer material for supercapacitors with large capacitance, high energy and power densities and excellent cycle life

Green Car Congress

Supercapacitors work on a different charge-storage principle than rechargeable batteries, and consist of electrochemical double layers on electrodes, which are wetted by an electrolyte. When a voltage is applied, ions of opposite charge collect on both electrodes to form wafer-thin zones of immobilized charge carriers. —Kou et al.
