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 cells Bernhard Riegel received his PhD in inorganic chemistry at the University of Stuttgart. He worked in his postgraduate time at the Max Planck Institute for Solid state chemistry in Stuttgart, the University of Texas at Austin, followed by the Center of Solar Energy and Hydrogen Research in Ulm (ZSW).Since 2001 he is working for HOPPECKE batteries with the responsibility as the director for Research and Development.His major R&D experiences are in the field of electrochemistry of lead-acid, alkaline and Li-Ion batteries. Jürgen Garche,Institute of Theoretical Chemistry, University of Ulm, Ulm, GermanyJürgen 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).
