Sulphur-based redox flow battery with 15 consecutive hours of runtime
Researchers from Hong Kong have applied a novel charge-reinforced, ion-selective (CRIS) membrane to a polysulfide-iodide redox flow battery they had built in 2016. The redox flow battery showed a capacity decay rate of just 0.005% per day for 1,200 cycles, and a lifetime with over 2,000 hours’ cycling, which the academics said corresponds to approximately three months.
