Optimizing Battery Separator Performance
Lithium-ion battery separators play a critical role in ensuring safety, performance, and longevity. This webinar explores advanced pore characterization techniques, Capillary Flow Porometry (CFP) and Mercury Intrusion Porosimetry (MIP), used to analyze separator materials. We’ll discuss the differences between through and blind pores, and how these affect battery function. Using experimental data from Celgard monolayer […]

Pore Characterization Of Lithium Ion (Li-ion) Battery Separators
Introduction Lithium-ion batteries (LIB) are widely used in consumer electronic devices. They have high energy densities and are rechargeable, resulting in sustained performance across many charging cycles. LIBs consist of an anode, electrolyte, separator, and a cathode, see Figure 1 below. LIBs use a separator, which is a permeable membrane placed between the battery’s anode […]

The Easiest, Most Accurate, Most Versatile Measurement Of Through-porosity
Expanding the Material Characterization “Toolbox” for Excipient and Active Pharmaceutical Ingredient (API) Vendor Qualification
Physical characterization of pharmaceutical excipients is not only a requirement but can also provide data that can be predictive in nature regarding the performance of final dosage forms including tablets, capsules, inhaled dosage forms, transdermals, and others. Manufacturers generally provide some of this physical testing data, such as particle size. In the case of particle […]
Bulk and Skeletal Density Computations for the AutoPore
Mercury porosimetry as performed by the AutoPore is primarily intended to measure the total volume of pores within a sample between an upper and lower limit of pore sizes with a 1% accuracy level. In addition to porosity, mercury porosimetry also is often used to measure the bulk density and the skeletal density. Relative to […]
Characterizing Li-Ion Battery Separators – Pore Structure Determination
The AutoPore V uses mercury porosimetry that can be used for characterization of Li-ion battery separators and electrodes. This uniquely valuable technique delivers speed, accuracy, and characterization of properties critical to safety, energy density, and longer cycle life. The MicroActive software equips users to interactively evaluate data by allowing them to easily include or exclude […]
Equilibrated versus Scanning Porosimetry
The porosity of solids and powders is frequently characterized by mercury intrusion porosimetry. This technique provides detailed information on pore volumes, density, and pore-specific surface area, while also yielding information that can be used to characterize the shape and structure of pores. To perform mercury intrusion porosimetry, various levels of pressure are applied to a […]
Using the Correct Penetrometer Constant with your Mercury Porosimeter
When performing mercury porosimetry analyses, it is important to use the correct penetrometer constant. The penetrometer stem holds the quantity of mercury that will be forced into the pores of the sample during the run. Since the exact pore volume that has been filled at each pressure reading is needed, it is necessary to know […]
