The increasing demand for high‐energy powers have greatly incentivized the development of lithium carbon fluoride (Li||CFx) cells. Five kinds of non‐aqueous liquid electrolytes with various kinds of lithium salts (LiX, X=PF6−, TFSI−, BF4−, ClO4−, and CF3SO3−) were comparatively studied. Intriguingly, the LiBF4‐based electrolyte show relatively moderate ionic conductivities; yet, the corresponding Li||CFx cells deliver the highest discharge capacities among them. A combination of morphological and compositional analyses of the discharge CFx cathode suggest that the moderate donicity of BF4− anion is accountable for favoring the breakdown of C−F bonds, and subsequently forming crystalline lithium fluoride as the main discharge products. This work brings not only fresh understanding on the role of salt anions for Li||CFx cells, but also inspire the electrolyte design for other conversion‐type (sulfur and/or organosulfur) cathode materials desired for high‐energy applications.

The burgeoning Li‐ion battery is regarded as a powerful energy storage system by virtue of its high energy density. However, inescapable issues concerning safety and cost aspects retard its prospect in certain application scenarios. Accordingly, strenuous efforts have been devoted to the development of the emerging aqueous Zn‐ion battery (AZIB) as an alternative to inflammable organic batteries. In particular, the instability from the anode side severely impedes the commercialization of AZIB. Constructing an artificial interphase layer (AIL) has been widely employed as an effective strategy to stabilize the Zn anode. This review specializes in the state‐of‐the‐art of AIL design for Zn anode protection, encompassing the preparation methods, mechanism investigations, and device performances based on the classification of functional materials. To begin with, the origins of Zn instability are interpreted from the perspective of electrical field, mass transfer, and nucleation process, followed by a comprehensive summary with respect to functions of AIL and its designing criteria. In the end, current challenges and future outlooks based upon theoretical and experimental considerations are included.

“…[1][2][3][4][5] These modifications in turn have rendered molecules that are useful for the pharmaceutical, agrochemical, and materials industries. [4][5][6] Therefore, over the past decade, great interest has been devoted to developing new methodologies for incorporating these simplest of fluorinated functionalities. However, the less common fluorinated functionalities like the -ZCF3 (Z=O,N) groups have not received as much attention due to synthetic challenges in their preparation and handling.…”
