Tuning the d-Band Center via High-Entropy-Induced Lattice Strain Enables Reversible Nanosheet-like Li2O2 Electrocatalysis
The reversible formation/decomposition of Li2O2 is central to nonaqueous lithium–oxygen (Li–O2) batteries, where sluggish oxygen redox kinetics causes large polarization and limited capacity, undermining their otherwise high theoretical energy density. Here, a high-entropy sulfide catalyst ((CoFeNiMnZn)3S4) is fabric...
