The coordination environment of Ru centers determines their catalytic performance, however, much less attention is focused on cluster‐induced charge transfer in a Ru single‐atom system. Herein, by density functional theory (DFT) calculations, a competitive coordination‐pairing between Ru clusters (RuRu bond) and single‐atoms (RuO bond) is revealed leading to the charge redistribution between Ru...

Metal‐organic frameworks (MOFs) fillers are emerging for composite polymer electrolytes (CPEs). Enhancing Lewis acid–base interaction (LABI) among MOFs, polymer and Li‐salt is expected to promote Li+‐transport. However, it is unclear how to customize a strong LABI interface. The large surface‐area of classical MOFs also interferes with clarifying the LABI influence on Li+‐transport. Herein, Bi3+ as...
