Properties of aprotic electrolytes for lithium-ion accumulators
Staněk, Vladimír ; Máca, Josef (referee) ; Frk, Martin (advisor)
The present work deals with the properties of suitable electrolytes for lithium-ion batteries. The first part described in the current issue of electrolytes for lithium-ion batteries, types of solvents and their properties and methods of measurement properties. The second part is devoted to the measurement of the properties of solvents and electrolytes such as relative permittivity, density and viscosity. Measurement of relative permittivity was focused on the measurement of the solvent mixture with varying the percentage of the solvent. Viscosity and density were measured on a solvent with a lithium salt added (final electrolyte).
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.
