MAHLE Powertrain and Allotrope Energy unveil lithium-carbon battery technology with ultra-fast recharging

Green Car Congress

MAHLE Powertrain and Allotrope Energy have unveiled a new battery technology which offers ultra-fast recharging coupled with good power density. Lithium-carbon battery. A 500 Wh conventional lithium-ion battery would require a recharge mid-shift that, even with a fast-charger, would take more than 30 minutes.

MIT team synthesizes all carbon nanofiber electrodes for high-energy rechargeable Li-air batteries

Green Car Congress

The carbon nanofiber electrodes are substantially more porous than other carbon electrodes, and can therefore more efficiently store the solid oxidized lithium (Li 2 O 2 ) that fills the pores as the battery discharges. In that work, the carbon structures were more complex but only had about 70% void space.

MIT and Harvard team develop material that stores sun’s heat

Green Car Congress

Researchers from MIT and Harvard University have developed a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand. In effect, they behave as rechargeable thermal batteries: taking in energy from the sun, storing it indefinitely, and then releasing it on demand.
