dc.description.abstract | Herein, a new solvation strategy enabled by Mg(NO3)(2) is introduced, which can be dissolved directly as Mg2+ and NO3- ions in the electrolyte to change the Li+ ion solvation structure and greatly increase interfacial stability in Li-metal batteries (LMBs). This is the first report of introducing Mg(NO3)(2) additives in an ester-based electrolyte composed of ternary salts and binary ester solvents to stabilize LMBs. In particular, it is found that NO3- efficiently forms a stable solid electrolyte interphase through an electrochemical reduction reaction, along with the other multiple anion components in the electrolyte. The interaction between Li+ and NO3- and coordination between Mg2+ and the solvent molecules greatly decreases the number of solvent molecules surrounding the Li+, which leads to facile Li+ desolvation during plating. In addition, Mg2+ ions are reduced to Mg via a spontaneous chemical reaction on the Li metal surface and subsequently form a lithiophilic Li-Mg alloy, suppressing lithium dendritic growth. The unique solvation chemistry of Mg(NO3)(2) enables long cycling stability and high efficiency of the Li-metal anode and ensures an unprecedented lifespan for a practical pouch-type LMB with high-voltage Ni-rich NCMA73 cathode even under constrained conditions. | en_US |
