Nanoengineering of Cathode Catalysts for Li–O2 Batteries

“…28,84,85 This modulation of discharge products can alter the charging process and charge overpotential, ultimately enhancing the battery's cycling stability. 32,86,87 Cathode catalysts consisting of rGO and iridium nanoparticles (Ir-rGO) have been employed in high-performance Li−O 2 batteries, where the main discharge product is LiO 2 rather than Li 2 O 2 (Figure 5a). 21 The experimental results coupled with density functional theory (DFT) analysis demonstrated a strong correlation between the formation of LiO 2 and the lattice matching of LiO 2 and Ir 3 Li (Figure 5b).…”

“…By utilizing nanoporous gold (NPG) as the cathode electrode and employing a dimethyl sulfoxide-based electrolyte, a superior capacity retention of up to 95% even after 100 cycles could be achieved for Li–O 2 batteries . Moreover, several noble metals can stabilize the LiO 2 intermediate, enabling the control of discharge product types in Li–O 2 batteries. ,, This modulation of discharge products can alter the charging process and charge overpotential, ultimately enhancing the battery’s cycling stability. ,, Cathode catalysts consisting of rGO and iridium nanoparticles (Ir-rGO) have been employed in high-performance Li–O 2 batteries, where the main discharge product is LiO 2 rather than Li 2 O 2 (Figure a) .
