Characterizing Li-ion Battery Separators: Pore Structure Determination

Lithium-ion (Li-ion) batteries are an advanced technology that will play a key role in the trend toward renewable and sustainable industrial electrification solutions. The AutoPore V Series utilizes the Mercury Porosimetry analysis technique, based on the intrusion of mercury into a porous structure under stringently controlled pressures. Besides offering speed, accuracy, and a wide measurement […]

The Mayer-Stowe Method for Determining Particle Size Using the AutoPore IV Series Porosimeters Theoretical

Theoretical models of mercury intrusion mechanisms allow information about particle size to be extracted. These models are included in the AutoPore IV Series data reduction package. In 1965, Mayer and Stowe* published a paper on the mercury breakthrough pressure required to penetrate a bed of packed spheres and the subsequent filling of the interstitial void. […]

Unraveling Hierarchical Pore Networks Using Differential High-Resolution Mercury Intrusion

The void structure of porous materials used as catalyst supports affects several properties such as permeability to liquids, gas diffusion, organic molecules access, availability of oxidation/reduction active sites, and so forth. Mercury intrusion porosimetry has been widely used to investigate the accessible pore volume starting from about 3.6 nm up to more than 600 µm. […]

Maximize Your Results from the Micromeritics AutoPore V – Demonstration

In this webinar, Tony Thornton, Micromeritics Director of Technical Information, will lead you through a brief demonstration of the AutoPore, from loading a sample in a penetrometer, through low and high pressure analysis, and pore size distribution analysis review. The AutoPore V series determines pore volume and pore area distributions as a function of pore […]

Porosity and Density Characterization of Freeze-Dried Organic Products: Case Study of Instant Coffee

The freeze-drying procedure is a common technique used in the food industry to dehydrate organic compounds. The technique, also known as lyophilization or cryodesiccation, is a method of food preservation by removing water content. Once the organic compound comes into contact with water again, it will resume its original properties such as consistency, taste, etc. […]

Unified Approach to Understanding Porous Materials

This webinar presents a generalized approach to modeling the pore size distribution which has been developed to determine the complete distribution of macro-, meso-, and micro-pores.Rather than using a fragmented approach of simple overlays from individual techniques, the Unified Method provides a full pore size distribution and improved estimate of total pore volume of the […]

Physical Characterization Methods for Cathode Powders

Anytime a powder is used in a process for a specific purpose, its behavior is often predicted by physical properties of the powder.  Determining the physical properties of a cathode powder can be used to decide which properties are critical to the performance of the cathode, as well as the battery in which it is used.  A sample of lithium iron phosphate (LFP) powder was characterized to determine […]

AutoPore V

Measures density, in addition to full porosimetry, especially for meso- and macro-porous materials.
