Book excerpt: Before the application of ionic liquids, it is important to know their fundamental physical and chemical properties. Practical experience has shown that it is important to look at these materials in the behaviour of the function frequency and temperature. To understand obtained information understanding the molecular-physic bases is needed. Research and application of ionic liquids have attracted an increasing attention in the areas of nuclear industry, oil and gas industry, petrochemical industry, chemical and electrochemical industry. The number of studies dealing with the question is proliferating which opens up new horizons in the field of chemical operations in microwave field with ionic liquids (organic chemical synthesis, catalytic operations, et cetera). As a result of the relatively high destroying temperature of ionic liquids, a wider temperature range of operations can be done and it offers environmental friendly solution in the replacement of the toxic solvents with generally low evaporating temperatures. The area of application is becoming more widespread as electrolyte of novel battery cells. Being aware of the physical and chemical properties of ionic liquids is necessary in order to apply them. The main goal of this research was to test the dielectric properties, viscosity and temperature dependence of the electrical conductivity. Based on our results, we can claim that significant temperature dependence of the three properties can be shown in the case of ionic liquids. These findings are crucial for the usability of applications, planning and preparing of production and optimization processes. The significance and importance of these results become even more obvious if we consider the fact that these energy storage cells are exposed to large temperature differences. The present study discusses the sample materials, their usage possibilities and the results of the research from the previous work of the author. In the case of ionic liquids, it is important to know their behaviour in electric field. In lot of cases, there is no fundamental difference between the static and dynamic behaviours. Static state (like in accumulators) is similar to the dynamic. Ionic liquids are well characterized and grouped with their dielectric behaviour. First of all a short summarizing of basics of the electrical permittivity and then a modelling procedure will be shown modelling lots of parameters using dielectric characteristic of material. At the end the practical usage and application will be shown by using ionic liquids as the electrolyte of batteries.
