Lithium Bond in High-Concentration Electrolytes
Abstract
High-concentration electrolytes (HCEs) are promising for rechargeable batteries, but the stabilization mechanism of their large-sized solvation structures is not fully understood. This Perspective highlights the crucial role of lithium bonds as secondary interactions analogous to hydrogen bonds in stabilizing HCEs. By analyzing bond parameters, experimental criteria, and coordination behavior, we demonstrate that lithium bonds form between lithium in aggregate micelles and diluents, solvents, and anions in outer solvation shells. The surrounding molecules attracted through lithium bonds act as the buffer layer to mitigate micelle collision and phase separation, thereby maintaining the colloidal integrity of HCEs. Finally, we outline future research directions for lithium bond chemistry to guide the advanced electrolyte design.
