| Popis: | The article deals with description of rheological properties of solvents for electrolytes of lithium-ion accumulators. Solvents mixture of dimethyl sulfone and sulfolane at different volume ratios and with a lithium salt (LiClO4) appear as potentially suitable electrolyte. The aim of this experiment is to investigate the rheological properties, particularly density and dynamic viscosity, of solvents with lithium salt in temperature dependence and to find the optimal composition of the electrolyte from the perspective of achieving the lowest dynamic viscosity and better electrical conductivity because both quantities are closely related in accordance with Walden's rule. The vibration method is used to determine the values of dynamic viscosity. |
