“…22 The relationship between lithium dendrite formation and the ionic transport properties of the composite polymer electrolyte is also discussed. 35 Matsumoto et al 36 reported that the LiTFSI ionic liquid in PP13TFSI enables the reversible plating-stripping of lithium metal. Figure 13 shows typical impedance profiles for the Li/ PEO 18 LiTFSI/Li and Li/PEO 18 LiTFSI-1.44PP13TFSI/Li cells at 60°C as a function of the storage time.…”

This article summarizes our research on aqueous lithium-air rechargeable batteries. Lithium-air batteries have a far higher energy density and lower material cost than lithium-ion batteries, so that they are now attracting growing attention as possible power sources for electric vehicles. Presently, two types of rechargeable lithium-air batteries have been developed; non-aqueous and aqueous types. The aqueous type has a lower specific energy density than the non-aqueous system, but overcomes some severe problems that must still be addressed for the non-aqueous type, such as lithium metal corrosion by water from air and the high polarization of electrode reactions. The key component of the aqueous lithium-air battery is a water-stable lithium metal electrode (WSLE). The WSLE developed in our laboratory consists of lithium metal covered with a lithium conducting polymer electrolyte and a lithium conducting water-stable solid electrolyte, which was successfully operated in a saturated LiOH and LiCl aqueous solution.

“…They found that not only the physical but also the electrochemical properties of the ILs depend mainly on the type of anions and cations . Also it was found that the introduction of alkoxy groups into the ILs might lower the viscosity hence increase the effectiveness of the battery based on such liquid (Matsumoto, 2000). The electrochemical windows, feasibility of ILs and the cycle life of batteries prepared with ILs were studied by Yang and co-workers (Xu, 2006).…”

“…On the other hand, some papers have been published on the use of aliphatic quaternary ammonium-based ionic liquids, which would be expected to have a higher cathodic stability; this is due to the fact that the small size aliphatic quaternary ammoniumbased ionic liquid has a relatively high melting temperature, compared with the aromatic ones. MacFarlane and co-workers reported that aliphatic quaternary ammonium cations which had relatively short (C1-C4) alkyl chains could not easily form an ionic liquid near room temperature , as cited in Sun et al,1997,1998a,1998b& MacFarlane et al,1999,2000. However, Angell and co-workers and Matsumoto et al reported that some asymmetric and short-chain aliphatic quaternary ammonium cations with a methoxyethyl or methoxymethyl group on the nitrogen atom formed ionic liquids below room temperature (Cooper & Angell,1986;Emanuel et al,2003) (Matsumoto et al,2000(Matsumoto et al, ,2001(Matsumoto et al, ,2002 Fig.…”
