Boosting a practical Li-CO₂ battery through dimerization reaction based on solid redox mediator.

ABSTRACT: Li-CO₂ batteries offer a promising avenue for converting greenhouse gases into electricity. However, the inherent challenge of direct electrocatalytic reduction of inert CO₂ often results in the formation of Li₂CO₃, causing a dip in output voltage and energy efficiency. Our innovative approach involves solid redox mediators, affixed to the cathode via a Cu(II) coordination compound of benzene-1,3,5-tricarboxylic acid. This technique effectively circumvents the shuttle effect and sluggish kinetics associated with soluble redox mediators. Results show that the electrochemically reduced Cu(I) solid redox mediator efficiently captures CO₂, facilitating Li₂C₂O₄ formation through a dimerization reaction invol
