Rinaldo Raccichini received his master’s degree in chemistry from the University of Camerino. He was awarded his doctorate from the University of Münster for work on the synthesis and electrochemical characterisation of active materials for metal-ion batteries and supercapacitors, followed by a research fellowship at the University of Southampton on the study and characterisation of materials for sulfur-based batteries. Rinaldo then worked at the UK National Physical Laboratory as electrochemical energy storage higher research scientist. He also served as editorial office for the Journal of Power Sources for several years Rinaldo was appointed as editorial board member of Electrochem and Chemistry Proceedings journals and guest editor for Energies. He is an indiepdent reviewer for various research institutes and peer-reviewed scientific journals. Rinaldo is currently a senior editor at Springer-Nature and his main scientific interests lie in the study of EES systems. More broadly, he retains a strong interest in all the different aspects of energy production, harvesting, storage, transformation, consumption, and sustainability. Ulderico joined Nissan in July 2019 as Battery Research Engineer. He is the technical coordinator for research projects on next-generation battery technologies at the Nissan Technical Centre Europe. Previously, he worked at OXIS Energy Ltd as Senior Scientist and Technical Leader for EU H2020 projects. He has published 16 peer-reviewed papers and filed 4 patents, in collaboration with several industrial partners such as BMW AG, Samsung R&D Japan, EVONIK Ind. AG, OXIS Energy Ltd. His main areas of expertise are solid-state and high energy lithium-ion batteries, with a particular focus on negative electrode materials and novel electrolyte formulations. He was awarded his doctorate (chemistry) in 2017 from the Karlsruhe Institute of Technology (Germany). Ulderico received his BSc and MSc degrees in Industrial Chemistry from the University of Rome "La Sapienza" (Italy).
