We are excited to collaborate with Dr. Johanna Sygusch from the Helmholtz Institute Freiberg for Resource Technology on our next webinar, exploring recent characterization research into advanced battery materials.
Nowadays many electronic devices are being operated by batteries, including everyday devices (e.g. laptop and smartphones), healthcare devices (e.g. toothbrush), tools, toys, and vehicles as well. The use of batteries is forecast to increase significantly in the upcoming years. Therefore, the development of long and high-performance batteries and also the need to recycle spent batteries in order to ensure the supply of critical raw materials increased significantly in the last years, but is a complex task since the individual batteries have rather complex structures and varying composition.
During the development of the battery materials, temperature stability is one of the key parameters besides energy density, power density, lifetime, charging rate, cost and safety. Furthermore, the understanding of the surface properties and interfacial interactions of the anode and cathode materials is crucial in order to improve and develop efficient manufacturing and recycling processes.
In this webinar we present the surface and interfacial properties of different cathode (LCO, NMC, LFP) and anode (natural and synthetic graphite) materials. Characteristic properties include the specific surface area, the surface energetics at different temperatures measured with inverse Gas Chromatography (IGC) as well as water and cyclohexane sorption behaviour by Dynamic Vapour Sorption (DVS). Furthermore, we are going to present some results on wettability characterization using optical contour analysis and the Washburn method, as well as bubble-attachment and analytical particle solvent extraction tests. We also discuss which challenges arise during the recycling of spent lithium ion batteries by using the separation process of froth flotation.
Dr. Sygusch and Dr. Kondor will, among other things, give a detailed introduction to the Inverse Gas Chromatography and Dynamic Vapor Sorption techniques. With a live Q&A to finish the session, this is an unmissable opportunity to gain fresh insight into this vitally important topic from two leading experts.

Inverse Gas Chromatography (IGC) is a rapid technique to determine thermodynamic parameters of gas-solid interactions and to characterize physicochemical properties of solid substrates. IGC offers its applicability where it is difficult and even impossible to characterize the surface of some forms of solids (powders and particulates) by means of other popular techniques as wetting method or FTIR. Solids and highly viscous liquids in many forms can be easily studied by means of IGC . In this short presentation, we show three applications of IGC at high temperature and we introduce the new IGC- SEA system with high temperature oven.
First, adsorption isotherm data of several alkyl aromatic hydrocarbons (benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene) were measured in the temperature range of 423–523 K on a partially dealuminated faujasite type DAY F20 zeolite by inverse gas chromatography. The gas–solid equilibria and modelling were interpreted on the basis of the interfacial properties of the zeolite, by dispersive, specific and total surface energy heterogeneity profiles and distributions of the adsorbent measured by surface energy analysis.
Diffusion and mass transfer play a significant role in several materials processing operations. Diffusion and mass transfer are also of crucial importance in affecting the structure of solid products including segregation phenomena in castings and impurity distribution in crystal growth . In the second study diffusion coefficients of cyclohexane and toluene on two catalyst samples were measured at 523 °C and 573 K and the uncertainty in the measurement was also determined.
In the last study, we investigated the thermal stability of anode and cathode materials by measuring the surface energetics at different temperatures, which is important during development of the battery materials, besides energy density, power density, lifetime, charging rate, cost and safety.

The Importance of Surface Energy and Wettability in Biomaterials with Dr. Daniel J. Burnett
Surface energy is an important parameter for the characterization of surface properties. It can provide a useful picture of the energetic situation on the surface and shows a strong dependency on various macroscopic material properties. For example, it is directly related to the interfacial adhesion between two surfaces. In particular to biomaterials understanding the surface interactions of these materials becomes important as these could influence their biological reactivity, binding or adsorption interactions in different bioprocesses as well as the functionality of several biomolecules. In this review presentation, several case studies focused on measuring the surface energy and wettability of proteins, bioglasses, bone cements, and dental materials will be introduced. Work is highlighted by recent investigations from the authors. In particular, the surface energy as a function of relative humidity was investigated on proteins and glycine oligomers. In addition, previously published work from other groups will be introduced.
Surface Energy and Surface Area Studies on Pharmaceutical Powders using Inverse Gas Chromatography with Prof. Daryl Williams
The surface characterization of pharmaceutical powders is critical for many of the unit processes which occur with the manufacture of particulate based solid state dosage forms. In particular, the surface energy and the surface area are arguably the most important two surface property descriptors. This presentation illustrates how IGC can be used to measure the surface area of low surface areas pharmaceutical solids, including the surface area as a function of relative humidity. In the main part of this talk, the wide range of unit processes will be highlighted where the importance of powder surface energy can be demonstrated including granulation, powder flow, powder milling and dissolution. In particular the usefulness of surface energy heterogeneity mapping using IGC will be highlighted.
