2.9. CO 2 redox flow battery (CRB) In order to demonstrate the polarization behavior of the CO 2 redox battery a preliminary cell design was used with continuous flow of CO 2 gas to GDE coupled with batch liquid electrolytes, negolyte and posolyte, respectively (Figs. 5 and S13, Supplementary Information).
A new wave of electrochemical technologies proposed recently is focused on the utilization of CO 2 in primary and secondary (rechargeable) batteries [,, ]. In this pathway, CO 2 either alone or in combination with other species (e.g., O 2) is an electroactive species in the battery.
This flow cell demonstrated substantial oxygen compatibility, exhibiting a coulombic efficiency of 99% and requiring only 73 kJ mol−1 CO2 for simulated flue gas and 104 kJ mol−1 CO2 for DAC.
The latter redox couple has been used in a variety of flow battery technologies (e.g., organic redox flow, vanadium, zinc, sulfur) [,,, ], some material selection and safety related challenges notwithstanding.
Metal–CO2 batteries, which use CO2 as the active species at cathodes, are particularly promising, but device design for mass-producible CO2 reduction and energetic power supply lag behind, limiting

Electrochemical CO2 capture is hindered by the oxidation of redox-active organic molecules by O2, affecting energy efficiency and capacity. Here the authors develop a flow cell in
In the redox flow battery system, the formation of Ir IV and high-valence hydride species, in contrast to the case of the chemical hydrogen battery, worked as active species and was supported by the in
Metal-CO2 batteries have been considered a promising approach to neutralising the global CO2 level, but they still suffer from poor energy efficiency and cycling stability. This project
