Conductivity Of Lithium Perchlorate Salt Dissolved In Different Types Of Solvent
Gottwald, Tomas ; Vondrák, Jiří
Lithium perchlorate (LiClO4) is usable crystalline salt for electrolyte in a rechargeable lithium ion battery (LIB). LiClO4 is an inorganic compound with white color. In the present study the conductivity and the electrochemical behavior of electrolytes based on LiClO4 was examined by using impedance spectroscopy (EIS) and linear voltametry (LSV) measurement at a room temperature. The resistance (conductivity) of electrolytes with different molar concentration of LiClO4 dissolved in different types of the solvent was measured in the first part of this work. In the second part electrochemical behavior of two electrolytes with the highest conductivity was measured and evaluated by using a potential window. At the end the sodium perchlorate NaClO4 (for NIBs) was measured in this study too.
