“…Similar pair formations were also found in typical carbonate‐based electrolytes that have been extensively used in commercial Li‐ion batteries, [ 22 ] such as LiPF 6 in ethylene carbonate (EC) and dimethyl carbonate (DMC) 1:1 volume ratio or 1.27:1.0 molar ratio. We confirm again that the environment in the electrolyte changes upon Li + solvation process (Figure S16b and S17 , Supporting Information).…”

Solvent-solvent and solvent-anion pairings in battery electrolytes have been identified for the first time by nuclear magnetic resonance spectroscopy. These hitherto unknown interactions are enabled by the hydrogen bonding induced by the strong Lewis acid Li + , and exist between the electron-deficient hydrogen (𝜹 + H) present in the solvent molecules and either other solvent molecules or negatively-charged anions. Complementary with the well-established strong but short-ranged Coulombic interactions between cation and solvent molecules, such weaker but longer-ranged hydrogen-bonding casts the formation of an extended liquid structure in electrolytes that is influenced by their components (solvents, additives, salts, and concentration), which in turn dictates the ion transport within bulk electrolytes and across the electrolyte-electrode interfaces. The discovery of this new inter-component force completes the picture of how electrolyte components interact and arrange themselves, sets the foundation to design better electrolytes on the fundamental level, and probes battery performances.

“…As shown in the XRD θ−2θ patterns (Figure 1b), diffraction peaks appeared at 17.3°, 23.6°, 28.2°, 31.9°, and 41.3°were indexed to the (120), ( 130), (121), (221), and (520) facets of Bi 13 S 18 I 2 (PDF: 73-1157), respectively. 18,22,23 It is confirmed that Bi 13 S 18 I 2 was synthesized between 300 and 400 °C. At 350 °C, the intensity of the (130) diffraction peak was much stronger than that at 300 °C, which might be caused by the large film thickness and continuous surface morphology (discussed in the SEM part).…”

Bismuth-based ternary compounds have attracted much attention owing to their various merits, such as low toxicity and tunable electrical and optical properties. However, these compounds are yet to be understood due to the lack of suitable targets limited by immature synthesis techniques. In this work, we aimed at the synthesis, properties investigation, and photodetection application of Bi 13 S 18 I 2 . Mist chemical vapor deposition was adopted for the deposition of the Bi 13 S 18 I 2 thin film for the first time. The deposition mechanism was discussed from the perspective of crystal phase and surface morphology. Based on the Bi 13 S 18 I 2 thin film synthesized at optimal temperature, we constructed a photoelectrochemical-type photodetector. The photodetection performance was evaluated from the points of electrolyte composition, working temperature, and bias voltage. This study would pave the way for the controllable synthesis and applications of bismuth-based ternary compounds.

Nanocrystals of all-inorganic metal chalcohalides having a combination of chalcogen and halogen anions with appropriate crystal structure and bandgap can be ideal semiconductors in comparison to the well-established multicomponent family of nanostructures. These materials are one of the overlooked semiconductors which could play a paramount role in photocatalysis due to their stability, low-dimensional (1D) structure, and suitable bandgaps with efficient light-responsive nature. Emphasizing these materials, in this Review, recent developments in the design and application of different chalcohalide nanostructures are reported. The initial part is focused on the syntheses and crystal structures of reported chalcohalide materials, followed by an overview of their photocatalytic applications in different aspects. Finally, the successes and challenges associated with the future progress using these materials are discussed. This Review will provide an extended understanding and offer a preferred direction for the innovative design of these materials for environmental and especially energy-based applications.
