Iodine-Based Electrolyte Chemistry Enabling Reversible Ca Metal Anodes.

ABSTRACT: Electrolyte chemistry is of paramount importance for tackling the challenge of irreversible Ca deposition/stripping caused by ionic-insulating solid electrolyte interphases (SEIs). Current research has been mainly concentrating on the boron center-based electrolytes despite their complex synthetic procedure and leaves aside others because of a virtually inhibited electrochemical response. Herein, we report a kind of iodine-based electrolytes comprising CaI₂ salt paired with auxiliary iodides, in which the latter elevates the I^- concentration to reconfigure electrical double-layer structures of a low-solubility CaI₂ electrolyte, thus accelerating Ca²⁺ desolvation and Ca²⁺ diffusion across SEI. Consequently, the optimized iodine electrol
