Chinese scientists have analyzed reports of thermal issues with vanadium redox flow batteries (VRFB) and existing thermal management methods. They say the operating temperature should be maintained in the range of 10 C to 40 C to ensure VRFBs with high efficiency, weak side reactions, high electrolyte stability, and low crossover.Unlike lithium-ion batteries, vanadium flow batteries store energy in a non-flammable, liquid electrolyte and do not degrade with cycling. They hold the promise of more than 10-hour duration storage, high recyclability, and 25 years or more lifespan. However, these batteries ...Den vollständigen Artikel lesen ...
