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. Huskinson et al.

ORNL demos 20 kW bi-directional wireless charging on UPS PHEV truck; 11" air gap, >92% efficiency

Green Car Congress

The system transferred electricity from the power grid to the vehicle battery terminals at more than 92% efficiency. At a 20-kilowatt level, it would take about three hours to charge the vehicle’s 60-kilowatt-hour battery packs. ORNL’s bidirectional technology is fully compliant with grid power quality standards.

Study Finds PHEV Li-ion Cells Show Little Capacity Fade Under Combined Driving and V2G Usage; Economic Model Suggests Incentives Will Be Required for Vehicle Owners to Participate in V2G

Green Car Congress

Statistical analyses indicated that rapid battery cycling incurred when driving degraded the cells more than slower, vehicle-to-grid galvanostatic cycling. The quantify the capacity degradation of the pack, the authors derived a nominal urban driving/V2G power profile and correlated battery test regime by combing several common data sets.
