Interfacial Chemistry Enables Stable Cycling of All-Solid-State Li Metal Batteries at High Current Densities

Biyi Xu et al.

Summary: The addition of Mg(ClO4)(2) into PEO-based composite electrolyte effectively regulates Li+ ion transport and enhances the Li+ ion mobility, leading to the formation of a conductive Li2MgCl4/LiF interfacial layer that homogenizes Li+ flux and increases the critical current density to a record 2 mA cm(-2). These findings highlight the importance of surface chemistry and interfacial engineering in designing high-current-density all-solid-state Li metal batteries.

Lithium Metal Batteries Enabled by Synergetic Additives in Commercial Carbonate Electrolytes

Nan Piao et al.

Summary: By introducing lithium nitrate (LiNO3) and fluoroethylene carbonate (FEC) into commercial 1 M LiPF6/EC-DMC electrolytes, an inorganic-enhanced LiF-Li3N SEI was designed to improve the Li plating/stripping Coulombic efficiency to 99.6% in 100 cycles. This strategy enabled a lithium metal anode cell to achieve an average CE of 99.7% and a capacity retention of 90.8% after 150 cycles, demonstrating high performance in commercial carbonate electrolytes.
