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.

Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes

Green Car Congress

A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. Hard carbon materials of various morphologies are commonly prepared by direct pyrolysis or hydrothermal decomposition of biomass. However, the Purdue team noted, with its low operating voltage (.
