Binary Network Forming Salts

There is some information in the literature regarding these molten salts beyond the data in Table 4.1. The structure of the network forming salts has been studied by means of the methods already discussed in Sect. 3.2 for highly Iotuc high-melting salts. A common feature is the existence in the MX2 melts of a close-packed anirm (X = F, Cl , 0 ) structure with the multivalent cations (M = Be , Is , Si

In 2001, a dye-sensitized solar cell assembled with a gel network polymer electrolyte based on polysiloxane and PEO, containing 20 wt% of Lil, 5 wt% of h and 150 wt% of the mixture ethylene carbonate (EC)/propylene carbonate (PC) (3 1 v/v) was reported. EC is a high viscosity solvent with high dielectric constant, which is favorable for salt dissociation. However, this material has a tendency to crystallize at low temperature, causing phase separation between the plasticizer and the polymer matrix. Thus, organic solvents such as PC are used to form binary organic solvents with EC and homogeneous gel polymer electrolytes can be obtained. The fully cross-linked electrolyte presented ambient conductivity of 1.1 x 10 S cm and... 

As it is perfectly known, room temperature molten salts or ionic liquids (ILs) are charged complex fluids formed exclusively by ions. They can be seen as an infinitely concentrated electrolyte solution, and one can think about these systems as the opvposite limit to that of the applicability of the DH theory of ions solutions. It is well-known that a polar network exists in these systems, as can be seen for example in (Wei Jiang et al., 2007), so, from the theoretical perspective, one expects that a pseudolattice model is particularly well adapted to the peculiarities of ILs. Indeed, Turmine and coworkers (Bou Malham et al., 2007 Bouguerra et al. 2008) proved that the so called Bahe-Varela (BV) pseudolattice theory of electrolyte solutions is capable of accoxmting for the thermodynamic properties of binary and ternary mixtures of ILs up to the limit of pure IL.
