Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Li–O2 batteries garner widespread attention owing to their remarkable theoretical specific capacity. Nevertheless, the feasible implementation of the system is hindered by sluggish cathode reaction kinetics and poor anode stability. Herein, the carbon dots (CDs) with ‐OH, ‐NH2, and ‐COOH groups are synthesized and employed as electrolyte ...
