PC is also a very useful solvent of LIBs because of its superior ionic conductivity over a wide temperature range. However, despite the close structural similarity between EC and PC, PC cannot form as effective SEI films as EC does, for LIBs that employ graphite as negative electrodes. " To enable to use PC in these batteries, there have been a lot of efforts focusing on the identification of proper additives and/or co-solvents for PC-based electrolytes, which would help to generate an efficient SEI layer. The typical liquid additives include chloroethylene carbonate (CEC), other halogen-substituted carbonates, a variety of unsaturated carbonates such as vinylpropylene carbonate and vinylene carbonate, and ethylene/propylene sulfite (ES/PS). The most common co-solvents are DMC, DEC, EMC, y-butyrolactone (y-BL), dimethyl sulfoxide (DMSO), dimethyl formamide (DMF), dimethyl amide (DMA), 1,2-dimethoxy-ethane (DME) and 1,2-dimethoxy-methane (DMM). To explore the role of these additives and co-solvents, it is necessary to understand their structures and some properties that may affect the SEI formation on graphite anodes. [Pg.366]

The impedance measurement is shown in Fig. 14.14. A comparable interface resistance is observed with graphite anode vs. Li, between ionic liquid and reference electrolyte EC/DEC-LiPFs at 80 However, EC/DEC-LiFSI based salt showed a lower interface impedance at 65 In the diffusimi part, the ionic liquids show higher resistance (20 and it increases in the order given in Eq. (14.5). Due to the high viscosity of the IL, the diffusion resistance is consequently higher. [Pg.566]

An electric generator or battery forces electrons into tl e cathode and pumps them away from the anode—electrons move freely in a metal or a semi-metallic conductor such as graphite. But electrons cannot ordinarily get into a substance such as salt the crystalline substance is an insulator, and the electrical conductivity sliowu by the molten salt is not electronic conductivity (metallic conductivity , but is conductivity of a different kind, called ionic conductivity or electrolytic conductivity This sort of conductivity results from the motion of the ions in the liquid the cations, Na+, are attracted by the negatively charged cathode and move toward it, and the anions. Cl , are attracted by the anode and move toward it (Fig. 10-1). [Pg.211]
