Viscosity measurements can be used to evaluate the performance of Lithium-ion battery electrolytes. The Lithium-ion battery electrolytes have been typically made with a lithium salt dissolved in a mixture of cyclic and linear carbonates. The battery performance and lifetime capabilities strongly depend on the type of electrolyte.

In this application note, viscosity is measured for different electrolyte systems containing lithium salt (LiClO4), ethylene carbonate (EC), ethyl methyl carbonates (EMC), and dimethyl carbonate (DMC) using the VROC® initium one plus to understand the effect of solvent composition and salt concentration on the shear viscosity of battery electrolytes.
