Władysław Wieczorek is professor of chemistry (chemical technology) at the Warsaw University of Technology. He specializes in the design and development of new electrolytes and their components for lithium-ion and post-lithium-ion batteries, in particular sodium-ion, lithium-sulphur, as well as fuel cells, supercapacitors, and electrochromic devices. His major scientific achievements include the development of the concept of composite polymeric electrolytes, use of organic anion receptors to enhance lithium conductivity in electrolytes, development of the concept of non-aqueous proton conducting gel polymeric electrolytes for application in electrochromic devices and supercapacitors, and development of a novel family of Huckel-type salts for application in electrolytes used in lithium- and sodium-ion batteries, licensed in 2018 to the French Chemical Company, Arkema. Prof. Wieczorek is a leader in the field of design and development of new electrolytes and their components for lithium-ion and post-lithium-ion batteries in the frame of Alistore ERI and Battery 2030+ initiatives. He is also a co-founder of the Alistore European Research Institute, which focuses on electrolyte design and formulation. He has over 15 years of experience as a member of the didactic committee of the Erasmu Mundus Program Materials for Energy Conversion and Storage (MESC).
