Webinar: Reliable Ion Conductivity Determination of Electrolytes and Separators for Energy Storage Devices

 

Date:  Wednesday, December 14 at 10:00 am EST

The storage capacity performance of devices like batteries and supercapacitors can be improved by enhancing the ion-conductivity (???) of the electrolyte and the electrolyte-soaked separators. For lithium ion batteries, for example, the contribution of the Li+-ions to the overall ion-conductivity is a critical parameter defined by the Li+-ion transference number. Since most battery and supercapacitor applications occur over a wide temperature range, the temperature dependency of the conductivity and the overall transference number of the system is of great interest.
The routine measurement of a large number of samples requires a fast exchange of sample compartments, a reliable and quick adjustment of the sample temperature and an automatic analysis that improves throughput dramatically. This level of convenience offers significant time savings and can reduce the risk of errors.

In this webinar, the co-CEOs and founders of rhd instruments, an innovation-driven manufacturer of measuring cells and accessories for electrochemical research, will present the simple and user-friendly determination of temperature-dependent ??? values of battery electrolytes and electrolyte-soaked separators. Furthermore, you will learn about the benefit a sampling accessory provides to improve routine measurements that are time-consuming and prone to error.
