Properties of Electrolytes for Li – ion Batteries with Higher Fire Safety

Abstract

In modern Li – ion batteries are used, as part of the electrolyte organic solvents, which are flammable. In this work we are investigate the influence of different solvents and their mixtures on the flashpoint due find a solvent with increase the safety of such battery. We are taking the flashpoint as main safety parameter. Other properties that we observed are the specific conductivity and permittivity with both are important for solvent classification as appropriate for electrolytes usability. Another property for useable electrolytes is the melting point temperature and the temperature work window for lithium - ion batteries. In this paper it will be presented some properties of these mixtures from new solvents with commonly used solvents for aprotic electrolytes.
