Of the Li metal batteries the Li–O 2 battery has the highest theoretical specific energy. In their Communication on page 18394, Y.‐Y. Sun, T. Zhang, and co‐workers find that the synergic effect of the strong binding of RuO 2 to I 2 and the strong solvation effect of DMSO on I 2 could shift the direction of the well‐known reaction I − +I 2 ⇄I 3 − to the left‐hand side. A Li–O 2 battery with the Li/DMSO+LiI/RuO 2 structure had significantly enhanced stability compared to one with TEGDME.
