Density of Battery Components: Versatility of Gas Pycnometry in Measuring Powders, Films, Slurries

Measuring the skeletal density of materials in the battery industry can advance applications in energy storage and battery longevity. Gas pycnometry is well-suited to accurately and repeatably measure samples ranging from powders to films to semi-solids and has been utilized to measure skeletal density of components including electrode powders, separator films, and battery slurries.

One critical property of battery components is the skeletal density, which can be correlated to energy density, purity, crystallinity, capacity, temperature dependence, and lifetime. The components of batteries can be analyzed for skeletal density using gas pycnometry. This technique is favorable because it is quick and non-destructive, and is applicable to all of the main battery components (including metallic powders, polymer separators, and electrode slurries). The skeletal densities of battery components including electrode powders, separator films, and slurries were measured using the Anton Paar Ultrapyc 5000 and the data is presented and discussed.
