Diversity‐Driven Selection of Halogenic Electrolyte Additive Engineering for Rechargeable Batteries

Abstract

Electrolyte additives have been widely used to solve critical problems of electrodes and electrolytes in various rechargeable batteries. However, due to the lack of well-directed strategy, the selection for additives have consumed considerable efforts of researchers. In this study, a diversity-driven electrolyte additive of 5-bromo-2-(difluoro(3,4,5-trifluorophenoxy)methyl)-1,3-difluorobenzene (BDTMD) is directed synthesized, two different substituent groups are designed in the structure. With this newly-formulated electrolyte, the overpotential during the charging process of LiÀ CO 2 cells can be reduced to 3.8 V without any catalyst. Li metal electrode also shows a stable solid electrolyte interface layer and long cycling life of 1600 h. Based on the synergistic effect between F and Br, this study demonstrates an efficiently and well-directed strategy to synthesis electrolyte additives.

Urea catalytic oxidation for energy and environmental applications

“…Ideally, these technologies utilize sustainable energy to convert urea into non-toxic N 2 , CO 2 , and H 2 O molecules, simultaneously coupled with generation of clean fuel H 2 . [31][32][33][34] Research on the e-UOR can be traced back to the 1970s, initially utilizing noble metal catalysts such as Pt, Ru, Au, etc. [35][36][37] The high cost and low current density of the UOR for these catalysts greatly limit their practical application.…”

Transition Metal‐Based Catalysts for Urea Oxidation Reaction (UOR): Catalyst Design Strategies, Applications, and Future Perspectives

“…This leads to a hazardous mixing of the reaction products H 2 /O 2 gases. [4][5][6] Due to the slow kinetics associated with the OER has been a limiting factor in HER efficiency. Thus, it is crucial to investigate potential countermeasures that might help HER work more efficiently.…”
