María Rosa Palacín Peiró (Barcelona, 1968) is a Spanish scientist specialized in solid-state chemistry, electrochemistry, and materials for energy storage. She obtained her degree in Chemistry from the Universitat Autònoma de Barcelona in 1991 with an Extraordinary Award, later completing a master’s degree in Materials Science in 1993 and a PhD in 1995, also with distinction. She has developed most of her scientific career at the Institute of Materials Science of Barcelona (ICMAB-CSIC), where she progressed through several research positions, becoming a research professor in 2018. Her research focuses on the development and understanding of materials for rechargeable batteries, including established technologies such as lithium-ion and nickel batteries, as well as emerging systems like sodium-ion, magnesium, and calcium batteries. Her work aims to understand the structural and electrochemical mechanisms that occur within electrodes and electrolytes in order to improve battery performance, durability, and sustainability.

Throughout her career, Palacín has led numerous national and international research projects and has made important contributions to the field of advanced battery technologies. She is the author of more than 160 scientific publications and co-inventor of several patents related to electrochemical materials. In addition to her research activity, she has held leadership and institutional roles, including serving as deputy director of ICMAB and associate editor of the journal Chemistry of Materials. She has also been actively involved in international scientific networks and organizations focused on energy storage. Her work has been widely recognized with several awards and distinctions, including being named Fellow of the Electrochemical Society and receiving the Research Award from the International Battery Association, as well as being elected member of scientific institutions such as the Institut d’Estudis Catalans and the Royal Academy of Exact, Physical and Natural Sciences of Spain.
