Viscosity as a Probe of Battery Electrolyte Performance
Webinar
Lithium-ion battery electrolytes are typically composed of lithium salts and a mixture of cyclic carbonates, e.g., ethylene carbonate (EC), and linear carbonates, e.g., dimethyl carbonate (DMC) and/or ethyl methyl carbonate (EMC). 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. Various factors affect the viscosity and, hence, the battery’s performance. These include temperature, electrolyte concentration, and solvent composition.
In this webinar, we show how we use our VROC® technology to explore the temperature and concentration-dependent viscosity of small volume lithium perchlorate and lithium hexafluorophosphate battery electrolyte solutions with high resolution, high accuracy, and minimal evaporation. In addition, we present results for a wide temperature range that can be used to better design electrolytes for multiple applications.
