Tohoku team develops new electrolyte to support rechargeable calcium batteries

Green Car Congress

Scientists from Tohoku University have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries. High-energy-density and low-cost calcium (Ca) batteries have been proposed as ‘beyond-Li-ion’ electrochemical energy storage devices.

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. Electrochem.
