Lithium ethylene dicarbonate ((CH2OCO2Li)2) was chemically synthesized and its Fourier transform infrared (FTIR) spectrum was obtained and compared with that of surface films formed on Ni after cyclic voltammetry (CV) in 1.2 M lithium hexafluorophosphate (LiPF6)/ethylene carbonate (EC):ethyl methyl...

The solvation of a lithium ion has been of great importance to understand the structure and dynamics of electrolytes. In mixed electrolytes of cyclic and linear carbonates, the lithium solvation structure and the exchange dynamics of solvents strongly de
Li/Li+). The single reduction product was lithium ethylene dicarbonate with a trace amount of ethylene having two CO distinct vibrational frequencies at 1782 and 1800 cm− 1, refer to Fig. 5. They had reported two main findings. The first is that the SEI “breaths” as a function of ...
(i.e., LiPF6in EC solvent) inLIBsare predominately made of reduction products from the salt and solvent, such as lithium ethylene dicarbonate (LEDC) and lithium fluoride (LiF). As shown inFig. 2B and C, LEDC undergoes continuousdecomposition reactions, resulting in an evolving SEI made up ...
Examples of the olefin (a1) include alkenes having 2 to 30 carbon atoms (hereinbelow abbreviated as C), such as C2 to 3 alkenes {ethylene and propylene}, and C4 to 30 α-olefins (such as 1-butene, isobutene, 1-hexene, 1-decene, and 1-dodecene). Examples of the different monomer (...
Researchers have extensively studied the constituents of passivating SEIs on graphite anodes and have reported that lithium ethylene dicarbonate (LEDC, Eq. 6, Fig. 5a–d) [108] was the main component of SEIs formed with ethylene carbonate (EC) solvent [109] apart from electronically insulating ...
the structure of DMDOHD is very similar to that of dilithium ethylene di-carbonate (LEDC, Fig.1and Supplementary Fig.3), found recently as a key component of SEI generated from EC-based carbonate solvents30,38. DMDOHD can be also converted to LEDC through electrochemical reaction or saponifica...
and/or small organic lithium carbonates such as lithium ethylene dicarbonate (LEDC) that are sufficiently close to the metal surface to be enhanced. The same sharp signals are not observed for the LP30 + FEC sample, which suggests that the SEI is less porous to the electrolyte and/or ...
