Characterizing Advanced Battery Anodes with Gas Adsorption BET Surface Area and DFT Surface Energy​

Generally, a nitrogen isotherm is widely used to characterize a material for specific surface area and pore size distribution. Using this well-established gas adsorption method, graphite, a commonly used anode material for Lithium-Ion Batteries, was characterized. In this webinar, how the unique characteristics of a graphitic surface affect the appropriate BET range will be discussed as well as how a nitrogen isotherm can reveal the topology features of a graphitic surface using the DFT surface energy model, distinguishing the distribution of edge planes, basal planes, and defects.
