The production and refinement of precursor cathode active material (PCAM) involves some highly critical process steps.
This on-demand webinar looks at the vital role of pH and some other key process variables in determining PCAM quality and lithium-ion battery performance.
PCAM production requires tight pH control.
Li-ion battery PCAM is produced in stirred tank reactors. An undesired shift of only 0.1 pH can strongly influence particle size, distribution and shape, and can severely impact PCAM quality.
Topics covered include:
To obtain the densest possible layer of Active Material on the cathode, Cathode Active Material is manufactured in different but defined particle sizes. Tight pH control during the crystallization/precipitation processes of the Precursor CAM is vital in getting the right morphology. However, pH sensors are rarely capable of dealing with the process conditions.
Oxygen analysis of the reactor headspace ensures reliable inerting and prevents the formation of unwanted byproducts.
