Low-cost all-iron flow battery with high performance towards long-duration energy storage
文献摘要：
Long duration energy storage(LDES)technologies are vital for wide utilization of renewable energy sources and increasing the penetration of these technologies within energy infrastructures.Herein,we propose a low-cost alkaline all-iron flow battery by coupling ferri/ferro-cyanide redox couple with ferric/ferrous-gluconate complexes redox couple.The designed all-iron flow battery demonstrates a coulombic efficiency of above 99％and an energy efficiency of～83％at a current density of 80 mA cm-2,which can continuously run for more than 950 cycles.Most importantly,the battery demon-strates a coulombic efficiency of more than 99.0％and an energy efficiency of～83％for a long duration(～12,16 and 20 h per cycle)charge/discharge process.Benefiting from the low cost of iron electrolytes,the overall cost of the all-iron flow battery system can be reached as low as $76.11 per kWh based on a 10 h system with a power of 9.9 kW.This work provides a new option for next-generation cost-effective flow batteries for long duration large scale energy storage.
