Eduardo Cattaneo received a PhD in solid state physics from the University of Cologne. After working as a postgraduate at the physical-chemistry institute of the University of Bonn he joined in 1988 the R&D staff of HOPPECKE Batteries. He has more than 20 years R&D experience on battery technology including published works on continuous casting of lead grids, continuous plate making, lead alloys corrosion, VRLA batteries and anodic stability of electrolytes for Lithium-ion cellsBernhard Riegel completed his Ph.D. in Inorganic Chemistry at the University of Stuttgart in 1994. Subsequently, he undertook several research stays, including at the Max Planck Institute for Solid State Research in Stuttgart, followed by a research stay at the University of Texas in Austin. From 1998 to 2000, he worked at the Center for Solar Energy and Hydrogen Research in Ulm, focusing on electrochemical storage technologies such as lead acid and NiMH. Since 2001, he has been engaged in research and development at HOPPECKE Batterien GmbH & Co. KG. In 2003, he assumed the leadership of research and development for the entire HOPPECKE Group. In 2007, he played a pivotal role in establishing HOPPECKE Advanced Battery Technology GmbH (INTILION GmbH), introducing lithium-ion technology to the industrial battery market at HOPPECKE. Dr. Riegel serves as an advisor to Battery Research Germany (BMBF), Associate Delegate of the Battery European Partnership (BEPA), advisor to FFB Münster, and Technical Cluster Leader at EUROBAT.Jürgen Garche, graduated in chemistry at the Dresden University of Technology (DTU) in Germany in 1967. He was awarded his PhD in theoretical electrochemistry in 1970 and his habilitation in applied electrochemistry in 1980 from the same university. He worked at the DTU in the Electrochemical Power Sources Group for many years in different projects, mainly related to conventional batteries, before he moved 1991 to the Centre for Solar Energy and Hydrogen Research (ZSW) in Ulm, where he was, until 2004, the Head of the Electrochemical Energy Storage and Energy Conversion Division. He was Professor of Electrochemistry at Ulm University and Guest Professor at Shandong University - China, 2005, Sapienca University Roma - Italy, 2009, 2013, 2016, and 2023, TUM-CREATE - Singapore, 2014, 2015, 2016- 2016, Dalian Institute of Chemical Physics - China, 2016, CNR Institute for Advanced Energy Technologies, Messina - Italy, 2019. After he retired from the ZSW he founded in 2004 the consulting firm Fuel Cell and Battery Consulting (FCBAT). Since 2015 he is senior professor at Ulm University. He has published more than 300 papers, 10 patents, and 11 books, among others as editor-in-chief of the first edition of Encyclopedia of Electrochemical Power Sources. He is listed in "World's most Influential Scientific Minds by Thomas Reuters (2014) and in the book "Profiles of 93 Influential Electrochemists (2015).
