Lithium Hexafluorophosphate Battery Electrolytes

Electrolyte viscosity is a critical factor for the functioning of lithium-ion batteries, as it influences the mobility of ions between battery electrodes during charging & discharging cycles.

Since temperature changes can affect the electrolyte viscosity and, hence, the battery’s performance, it is important to design electrolytes with appropriate viscosity characteristics over wide temperature ranges relevant to battery applications, like arctic to tropical hot conditions. To design better batteries, it is of interest to probe the viscosity of battery electrolyte solutions accurately and reliably over wide temperature ranges.
