“…Solid-state Li-O 2 batteries that use Li 3 InCl 6 as an interfacial modifier have also been demonstrated ( 73 ). Considering the catalytic activity of halogen chemistry in Li-O 2 and Li-S batteries ( 73 , 107 , 108 ), using halide SSEs as solid-state catalysts for developing solid-state Li-O 2 and Li-S batteries is a promising direction.…”

The safety of lithium-ion batteries has caused notable concerns about their widespread adoption in electric vehicles. A nascent but promising approach to enhancing battery safety is using solid-state electrolytes (SSEs) to develop all-solid-state batteries, which exhibit unrivaled safety and superior energy density. A new family of SSEs based on halogen chemistry has recently gained renewed interest because of their high ionic conductivity, high-voltage stability, good deformability, and cost-effective and scalable synthesis routes. Here, we provide a comprehensive review of halide SSEs concerning their crystal structures, ion transport kinetics, and viability for mass production. Furthermore, their moisture sensitivity and interfacial challenges are summarized with corresponding effective strategies. Last, halide-based all-solid-state Li-ion and Li-S pouch cells with energy density targets of 400 and 500 Wh kg −1 are projected to guide future endeavors. This work serves as a comprehensive guideline for developing halide SSEs from material design to practical application.

“…The lithium-oxygen and lithiumsulfur batteries are considered to be next-generation batteries due to their high energy density. [1][2][3][4] It can be inferred that the prosperity of the two kinds of batteries is restricted to physical and chemical mechanisms. Insulating species (Li 2 O 2 and Li 2 S) and low-dissolution species (LiO 2 ) generate sluggish redox kinetics, resulting in poor cycle life and reversibility of batteries.…”

Li metal batteries have suffered from dendrite growth and its derived dead Li formation for a long time. A new lithium restoration method through the shuttling of redox mediators has been proposed recently. However, the side reaction of severe self‐discharge often occurs when some redox mediators are used. Here, a selection principle of redox mediators for reactivating dead Li in lithium metal batteries is put forward, which is able to reactivate the dead Li effectively and reduce the self‐discharge at the same time. Three redox mediators of ferrocene (Fc), 10‐methylphenothiazine (MPT), and thianthrene (Th) with different redox potentials are tested in LiFePO4|Cu anode‐free Li metal batteries to clarify the selection principle. Furthermore, 2,2,6,6‐tetramethylpiperidinooxy (TEMPO), which is speculated to be a suitable one for reactivating dead Li in lithium metal batteries, is verified. This work provides a universal selection principle of redox mediators and may boost its practical application in Li metal batteries.
