Characterizing Lithium Ion Battery Components for Better Performance and Manufacturing Quality

Anode and cathode materials require certain particle size, surface area and density characteristics. These represent crucial properties for charge and discharge, and for effective slurry preparation for foil coating. The resulting porosity and pore size distribution of the separator can and should be evaluated to understand manufacturing and performance variables.

This webinar will present laboratory methods for measuring dry powders, particles in suspension, slurries, coated foils and all types of separators.

Featured techniques will include:

  • Gas sorption,
  • Density measurement
  • Helium pycnometry
  • Laser light diffraction/scattering
  • Mercury intrusion porosimetry
  • Capillary porometry
  • Rheometry plus others

Suitable for scientists and engineers working in research, development and quality assurance.

Dr Martin A. Thomas has more than forty years of industrial experience in the characterization of powders and porous materials. After studying for his Master’s degree in analytical chemistry and then his Doctorate in inorganic/physical chemistry - both at the School of Chemistry, University of Birmingham (UK) - he joined Cookson Group's Central Research labs where he began his specialization in powders and porous materials. He joined ICI's Catalyst Research Centre (now a Johnson-Matthey facility) in 1985 and spent six years as a Principal Research Officer in charge of porous materials characterization.

In 1991 Dr. Thomas joined Quantachrome Instruments which became part of Anton Paar in 2018. He is currently serving as Lead Scientist for the Surface and Pores product line at Anton Paar.

Dr. Martin Thomas has authored several research articles and books and has also been co-author of ten patents relating to porous materials and their characterization.
