Porosity: A Critical Parameter for Both Coated and Pressed Electrodes
Creating cathodes and anodes usually involves bringing particles of active material together into a layer that contains the prescribed amount of active material in a predictable volume, but still allow enough space for electrolyte penetration.
This webinar will detail the methods used to quantitatively describe that pore space that is created, both in terms of volume (porosity) and pore size distribution. Measuring the porosity of the separator will also be addressed.
Key Learning Objectives
- Understand the different technologies behind the various available methods
- How pore structure is affected by particle size and manufacturing process pressures
- Differentiate the methods for pore volume from those for pore size
Dr Thomas has more than 40 years’ experience in porous materials characterization, much of that time associated with heterogeneous catalysts as well as battery materials, ceramics and pharmaceuticals. He joined Quantachrome Instruments in 1991 from ICI’s Catalyst Research Centre in the UK, and has served as Anton Paar QuantaTec’s Lead Scientist since 2020, supporting customers worldwide through webinars and seminars. He is co-author of the book “Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density” published by Springer.
