Application Note - Effect of Salt Concentration on Battery Viscosity

Viscosity measurements can be used to evaluate the performance of Lithium-ion battery electrolytes which are 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. Viscosity, dielectric constant, wettability and conductivity are critical factors that must be taken into consideration for successful development of battery electrolytes.

In this application note, steady shear viscosity is measured for mixtures of ethylene carbonate and lithium perchlorate (LiClO4) at 40°C using the VROC^® initium one plus to understand the effect of salt concentration.
