PHASE DIAGRAM FOR MIXTURES OF SULFOLANE -DIMETHYLCARBONATE FOR USING IN ELECTROLYTES FOR LITHIUM - ION BATTERIES

摘要

The aim of this work is to determine the melting point for different ratio of solvents. The solvent used for lower flammability- sulfolane, have a high melting point 27.5 °C. Sulfolane would greatly limit the range of temperatures where it can be used. That's why we need to add a second solvent, with modifies the mixture properties for becoming a batter use in lithio - ion batteris. As a second solvent was selected dimethylcarbonate, which is nontoxic and environmentally friendly.
