Schone 5.5 Single-election mechanism extended to reduction of linear carbonates 

The selected NMR spectra of these synthesized lithium alkyl ethylene dicarbonate and lithium alkyl propylene dicarbonate are shown in Fig. 5.7. 

The highly symmetric structure of LEDC results in simple spectra for both H and c nuclei. The NMR spectra of LEDC are in good agreement with the structure only one H signals at 3.53 ppm (for -O-CH2-CH2-O-), while only two C signals at 62.9 ppm (for -O-CH2-CH2-O-) and 157 pm for (-O-CO2-). As for the LPDC, the H NMR spectrum characterized three chemical shifts the doublet at 1.10 ppm for CH3- indicates a CH3-CH- substructure, while the multiplets between 3.37 and 3.81 ppm represent a characteristic split pattern of the -0-CH(CH3)-CH2-O-. NMR detected four nonisotropic C nuclei, which are located at 17.87 ppm (for CH3-), 66.50 ppm (for -O-CH2-), 67.8 ppm (for O-CHCCHa)-), and 160.50 ppm (for -C(=0)-). 

Zhnang et aL compared the FUR spectra of pure LEDC on Ni surface after cyclic voltarmnetry inl.2 M LiPFe EC/EMC electrolyte, and metallic lithium cleaved the same electrolyte, as shown in Fig. 5.8 [39]. By comparison of IR spectra, they established that LEDC is the predominant surface species on a Ni electrode after lithium deposition in LiPFg/ECdiMC electrolyte, confirming that at the lithiation potential the
