Electrolyte‐Mediated Stabilization of High‐Capacity Micro‐Sized Antimony Anodes for Potassium‐Ion Batteries

-solvent-anion complex, which can be tuned by changing the solvent type and anion species, is used to predict and control electrode stability. The results shed new light on the failure mechanism of alloying anodes, and provide a new guideline for electrolyte design that stabilizes metal-ion batteries using alloying anodes.
