a Molecular features of ClDEE. b ClDEE closely adheres to the outer of the primary solvation shell of Li+, compressing the interval between Li− and FSI− anions. c Compared to traditional concentrated electrolytes with abundant anions but a loosely packed structure, the compressed solvation structure electrolyte features more compact, small solvation clusters. This compact arrangement accelerates the breakdown kinetics of FSI− anion to form a robust SEI, minimizing the depletion of Li salts and the growth of the SEI, thus enabling highly reversible LMN.
