Using a salt bridge. Following directly from the calculation above, the first method of minimizing the junction potential is to choose an electrolyte characterized by similar transport numbers and activites for its anions and cations. However, such experimental conditions are usually impracticable.

A standard Li-ion battery electrolyte with different concentrations of the flame retardant triphenyl phosphate for high-power applications has been tested (68). The electrolyte characterization shows only a minor decrease in the electrolyte flammability for low triphenyl phosphate concentrations. The addition of triphenyl phosphate to the electrolyte leads to an increased viscosity and a decreased conductivity. The solvation of the lithium-ion charge carriers may be directly affected by the addition of triphenyl phosphate. This was found by Raman spectroscopy measurements and an increased mass transport resistivity. 

For a given solvent (electrolyte), characterized by viscosity. pH. ionic strength and composition, for a given tenqierature and other eiqierimental conditions, such as the absence or presence of an anticonvection medium, the rate of migration of a given substance is defined by its mobility (/i) in cm. sec (distance travelled per unit time at unit potential gradient). There are several circumstances which make the exact measurement of die mobility a tricky matter. One is the determina-... 

However, reliable information about dependence of the functional properties of complex nickelates on their chemical composition and structure is still absent, while any straightforward and accelerated design of cathode materials is to be based upon reliable (and independent upon their interaction with electrolyte) characterization of the ability of then-surface sites to catalyze the oxygen reduction as well as of oxygen mobility in the bulk. Several lanthanum-nickel-iron mixed oxides with perovskite structure have demonstrated promising performance as cathodes for IT SOFC with traditional YSZ and GDC electrolytes [111-112]. However, studies of the behavior of electrode materials in contact with ATLS electrolytes or that of ATLS-based composites are veiy scarce [113].
