Figure 8. (A) Schematic of a Li-CO2 battery with a solid RM(II)-BTC. (B) RM(II)-BTC reaction mechanism, showing reduction, CO2 reaction, and Li2C2O4 formation. (C) Cycling performance. (D) 3D space-filling diagram and reaction schematic for Li2C2O4 formation[133]. (E) DFT-calculation energy profiles of CO2 adsorption on TAPP-M (M = Mn, Co, Ni, Cu) molecules. (F) Four-electron pathway at the TAPP-Mn site. (G) Two-electron pathway at the TAPP-Co site[138].
