TEESMAT Webinar series

WEBINAR 1 – Photoemission spectroscopy applied to storage energy material

The first TEESMAT webinar, titled ‘Photoemission spectroscopy applied to storage energy material’, was presented by the expert Dr. Anass Benayad, Ingénieur-Chercheur at CEA-LITEN.

The X-ray Photoelectron Spectroscopy (XPS) is a powerful analytical tool to study the electronic and chemical structure of materials at the surfaces and interfaces regions. The interest in this spectroscopy is continually growing in diverse fields of fundamental and experimental research. After a brief introduction, we present the contribution of photoelectron spectroscopy to the characterization of the chemical and electronic properties of materials for lithium and post-lithium ion batteries. The protocols developed through XPS and electrochemical characterization paved the way to improve our understanding of the phenomena of solid electrolyte interphase and redox process involved during battery operating. Through case studies, we will emphasize the contribution of XPS to TEESMAT European project.

Dr. Anass BENAYAD (HDR), is a senior expert at the department of nanomaterial and nanotechnology of CEA-LITEN at the Platform of Nanocharacterization (PFNC). He is developing new activities around photoemission spectroscopy in operando mode to study the redox process and electrolyte degradation mechanism in lithium ion batteries. From 2006 to 2013, he was a senior researcher at Samsung Advanced Institute of technology (SAIT), where he was in charge of different projects related to material engineering for battery electrodes. Dr. Anass BENAYAD, is author and co-author of more than 100 review papers and 12 patents.

WEBINAR 2 – In line quality control, digitalization and traceability of battery electrodes during all process steps

The second TEESMAT webinar, titled ‘In line quality control, digitalization and traceability of battery electrodes during all process steps’, was presented by the expert Ph.D Catalina Gutierrez, International Sales Engineer at IN-CORE Systèmes.

Involved in the battery inspection since 2005, IN-CORE has developed several tools installed on the production lines to control the quality of the electrodes. The quality inspection LineaVision, based on high accurate line sensors, controls 100% of the electrode’ surface on both sides and checks the product compliance with quality request. During the electrode manufacturing the most important is to check very precisely all geometrical parameters which influence directly the electrodes performances. By identifying the coating process drift in real time, LineaVision contributes to reduce waste, improve yield and therefore participates in manufacturing costs optimization. LineaTrack, installed in the coating line, is IN-CORE’ tool to serialize each individual electrode whatever the coating pattern by engraving the unique 2D code. This code, which is timestamped and broadcasted in the MES/ERP, is used to link all essential parameters to each individual electrode including the quality status given by LineaVision. This is what we call full digitalization solution perfectly customized to the electrodes manufacturing level. Digitalization is key to EU Li-ion battery industry to develop competitive, high quality battery manufacturing capacities, integrating the 4.0 industry concept.

Ph.D Catalina Gutierrez is an engineer with Ph.D in mechanics and manufacturing processes. With a multi-cultural background, she joined the sales team of IN-CORE Systèmes 4 years ago and has been handling with the technical and commercial requirements of the highly-demanding industries of Li-Ion Battery and High-Security Paper & Printing.
