Quantachrome Instruments Textural Characterization Of Battery Materials

The ongoing incremental needs of battery-powered devices require the development of more powerful and safer energy technologies. Over the last decade, smarter synthesis procedures facilitated advances in the development of novel porous materials with tailorable structural and surface properties, which have clearly the potential to significantly improve the efficiency, performance and durability of various batteries, fuel cells and other energy storage devices. In order to support and optimize these design efforts, it is imperative to accurately characterize the physico-chemical properties of these materials with regard to surface area, pore network structure , pore size and pore volume distribution, and density. We will discuss key aspects and ongoing challenges regarding the state-of-the-art structural characterization of battery materials by applying a combination of experimental techniques including gas adsorption (coupled with advanced theoretical methods for data analysis), mercury porosimetry, capillary flow porometry and gas pycnometry.
