Thermodynamic Study Of Liclo4 Activity Coefficients In Aqueous Solution At (288.15, 298.15, And 308.18) K

The use of various electrolyte materials in a lithium ion battery must be studied under stable electrochemical conditions; therefore, the LiClO4 activity coefficients in water at the temperatures described in this work are the result of an electrochemical cell (ISE): Na-ISE vertical bar LiClO4(m)vertical bar ClO4-ISE. For this study, the determination of activity coefficients was carried out using the Pitzer and Debye-Huckel equations to represent the relationship between log gamma and molality. For the system used with the electrochemical cell, it has good the behavior of mean ionic activity coefficients of LiClO4 for all temperatures, and at a temperature of 298.15 K, there is good agreement between the experimental data and the data in the literature.
