Thermally regenerable redox flow battery. ChemSusChem. 2020 Aug 24;: Authors: Facchinetti I, Cobani E, Brogioli D, La Mantia F, Ruffo R Abstract The efficient production of energy from low temperature heat sources (below 100°C) would open the doors to the exploitation of a huge amount of heat sources such as solar, geothermal and industrial waste heat. Thermal Regenerable Redox-Flow Batteries are flow batteries that store energy in concentration cells which can be recharged by distillation at temperature <100°C, exploiting low temperature heat sources. Using a single membrane cell set-up and a proper redox couple (LiBr/Br 2 ), we have developed a Thermal Regenerable Redox-Flow Battery (TRB) able to store a maximum volumetric energy of 25.5 Wh dm -3 , which can be delivered at power density of 8 W m -2 . After discharging the 30% of the volumetric energy, a total heat to electrical energy conversion efficiency of 4% is calculated, the highest value reported so far in harvesting of low-temperature heat.
