USC team develops novel organic redox flow battery for large-scale energy storage

Green Car Congress

Scientists at USC have developed a novel water-based Organic Redox Flow Battery (ORBAT) for lower cost, long lasting large-scale energy storage. These properties render quinone-based redox couples very attractive for high-efficiency metal-free rechargeable batteries, they found. Schematic of ORBAT. Click to enlarge.

Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

the key to addressing the low-temperature capacity loss lies in adjusting the surface electron configurations of the carbon anode to reinforce the coordinate interaction between the solvated Li + and adsorption sites for Li + desolvation and reduce the activation energy of the charge-transfer process. C and maintained 85.9% —Lu et al.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

A team at the Ohio State University has developed a membrane that regulates bi-directional ion transport across it as a function of its redox state and that could be used as a programmable smart membrane separator in future supercapacitors and redox flow batteries. plugin EVs to Tesla’s 85 kWh battery pack). —Herya and Sundaresan.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

But we do actually need that energy to be generated,” says Alper Bozkurt, who with Veena Misra codirects the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University. Not least of those considerations is energy storage [and generation].” Rasmus W.
