Summary: This study reveals that the reductive stability of methyl acetate-based electrolytes is determined by the solvation structure dominated by anions. By using fluorobenzene, the entry of anions into the solvation shell is promoted, generating free methyl acetate and enhancing its lowest unoccupied molecular orbital energy. The designed electrolyte enables LiCoO2/graphite cells to exhibit excellent cycling performance at low temperatures, offering new approaches to designing electrolytes for low-temperature applications.

Summary: The synthesis and characterization of the first mesogenic donor-acceptor polyoxometalate (POM)-based hybrid were described. In the solid state, the compound exhibited birefringent behavior with lamellar organization, and the fluorescence of the organic donor unit was significantly quenched, attributed to the occurrence of an intramolecular charge-separated state.

Summary: The effect of ammonium chloride on bismuth electrodeposition from choline chloride-urea deep eutectic solvent (DES) was investigated through spectroscopic, thermal, and electrochemical studies. The results showed that adding ammonium chloride slightly altered the melting point of the DES and modified the crystallization peaks during electrodeposition. Additionally, the presence of the ammonium salt influenced the crystallization behavior and morphology of bismuth deposits.

Summary: Functionalization of a carbon electrode through the electrochemical reduction of ruthenium tris-bipyridine diazonium salts prepared in situ allows determination of anion nature in lithium and sodium battery electrolyte, detecting the presence of PF6- and ClO4- anions as well as fluoride anions from PF6- degradation. The study found a linear relationship between the current response and F- concentration, which has been applied to aging battery electrolyte to confirm the low solubility of LiF. This behavior could aid in analyzing electrolytes from the recycling sector.
