Chinese Academy of Sciences Reports All-Iron Flow Battery Running 6,000 Cycles With No Capacity Decay and 99.4% Coulombic Efficiency
A team at the Institute of Metal Research engineered a new iron-complex electrolyte that ran 6,000 cycles at 80 mA per square centimeter with no capacity decay and a 99.4 percent average coulombic efficiency, opening a possible low-cost route to long-duration grid storage.
