Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Application of 102-09-0

Understanding and controlling the (electro) chem. reactions between pos. electrodes and electrolytes is essential to enhance the cycle life and safety of Li-ion batteries. Previous computational and exptl. studies have shown that greater capacity loss of LiNixMnyCo1-x-yO2 (NMC) with increased Ni content can be attributed to the enhanced chem. oxidation of carbonate solvents by dehydrogenation and increased salt decomposition In this study, we examine the role of a di-Ph carbonate (DPC) additive on the interfacial reactivity of LiNi1/3Mn1/3Co1/3O2, LiNi0.6Mn0.2Co0.2O2, LiNi0.8Mn0.1Co0.1O2 (NMC111, NMC622 and NMC811). Diffuse reflectance IR Fourier Transform (DRIFT) spectroscopy on NMCs showed that adding DPC in the electrolyte suppressed signals associated with dehydrogenation of ethylene carbonate (EC) from LiNi1/3Mn1/3Ni1/3O2 to LiNi0.8Mn0.1Ni0.1O2 (NMC111 to NMC811). In addition, having DPC in the electrolyte was accompanied with less PF6– salt anion decomposition to form less-fluorine coordinated species such as lithium nickel oxyfluorides or PF3O-like species as revealed by combined IR spectroscopy and XPS for Ni-rich NMCs. Such observations are in agreement with previous work showing that DPC can increase the cycling performance of NMC811. The reduced reactivity between NMC such as NMC811 and electrolyte with DPC can be attributed to the formation of surface reaction products from the electrochem. oxidation of DPC occurring at lower voltages compared to the chem. oxidative dehydrogenation of carbonates. This hypothesis is supported by in situ IR spectroscopy measurements, which revealed electrochem. oxidation of di-Ph carbonate upon charging at 3.9 VLi, accompanied by the detection of a feature around 1824 cm-1 attributed to organic oxidation products adsorbed on the oxide surface, and a stable electrode/electrolyte interface on NMC811 at higher voltages. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application of 102-09-0).
