Georgia Tech researchers develop aluminum-foil-based anodes for all-solid-state Li-ion batteries

Green Car Congress

Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering, is using an aluminum-foil-based anode in a solid-state Li-ion battery to create batteries with higher energy density and greater stability. The new battery system is detailed in an open-access paper in Nature Communications.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

As she drives her electric vehicle to her mother’s house, Monique’s battery gauge indicates that it’s time to reenergize. Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). This battery, though, uses a completely new kind of fluid, called a nanoelectrofuel.

Penn State team devises new control strategy to enhance EV battery performance when driving in cold temperatures

Green Car Congress

Researchers at Penn State, with a colleague from EC Power, have devised a new control strategy that can rapidly restore EV battery power and permit full regeneration while driving at temperatures as low as −40 °C. The strategy involves heating the battery internally during regenerative braking and rest periods of driving.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Crucial to the idea of lowering the cost of battery materials, myo-inositol is an abundant organic compound familiar to industry. —Lee et al.
