Webinar: Battery Rheology: Understanding the relation between battery slurry properties and electrode performance

Wednesday, September 8, 2021 | 2:00 - 3:00 PM EST / 8:00 - 9:00 PM CEST

Lithium-ion batteries (LIBs) have been a critical part in many portable electronic and automobile industries in recent years. The multistep process used to manufacture battery electrodes must be closely controlled to produce components that deliver desirable mechanical and electrochemical performance. In order to achieve this, the rheological properties of the slurries used during processing must be optimized, since these properties affect important characteristics such as uniform particle distribution, slurry stability, ease of mixing, and coating performance, which impact on the properties of the finished electrode.

In this seminar, we will look at the processes involved in the manufacture of electrodes for Li-ion batteries and the importance of rheology within this context. We introduce rotational rheometry as a valuable tool for characterizing battery slurries and highlight the measurements that can usefully be performed. Example data from an experimental study of the impact of processing parameters on electrode performance illustrates the relevance of rheological characterization in the development and manufacture of high performance electrodes.
