Title: Nanoscale materials science and advanced battery tests for improved industrial manfuacturing in Gigafactories (NanoBat EU project)
Author: Ferry Kienberger, Keysight Labs Austria (NanoBat coordinator)
Abstract: The reliable electrical testing and diagnostic evaluation of battery cells is an important task in industrial automotive manufacturing, in battery quality control, and in battery recycling. In the first part we show different materials characterization and battery test methods, including advanced calibrations and error correction methods. Standard operating procedures (SOPs) are provided for electrochemical impedance spectroscopy, including metrological evaluation of accuracy and error sources. The new methods are currently evaluated in round-robin tests together with automotive manufacturers and national metrology institutes, also within the frame of the ongoing EU H2020 project ‘NanoBat’. Additionally, we show how the test data is used as input data to modeling algorithms to extract the equivalent electrical circuit parameters of the cell, relevant for evaluating the SoH (State of Health) and second life applications of batteries. Finally, we provide interoperable data formats for tests of energy materials and devices that interact with the larger scientific and industrial ecosystem, thereby providing robust industrial use cases for battery manufacturing Gigafactories.
Ferry Kienberger is Keysight Austria Country Manager and Keysight Labs Group leader on battery research since 2015. Prior to this he was Scientist at Agilent Technologies. His University education includes a PhD in 2002 on Technical Physics and the Habilitation in Nanotechnology in 2019, both at JKU Linz. The scientific track record includes 130+ scientific peer reviewed publications (including Nature Publishing Group, AAAS Science, PNAS USA, and IEEE Transactions) with an H-factor 41 and 5000+ citations; he supervised 10 PhD theses. He was coordinator and lead partner in 15+ EU projects for Keysight and Agilent, 7 national projects, 2 international projects (Economic Development Board EDB Singapore), and 3 metrology EU projects. He serves as a vice-chair for the Horizon Europe program and is a former member of OECD BIAC (Business and industry advisory council).
