Pierre Lannelongue obtained his master degree in Energy at the University of Montpellier, France, in 2015 after working on Solid Oxide and Protonic Ceramic Fuel Cells. In 2018, he received his PhD in Chemistry and Physico-Chemistry of Materials from the University in Montpellier, which was carried out at the Institut Charles Gerhardt Montpellier (ICGM), in collaboration with the Institut des Matériaux Jean Rouxel de Nantes (IMN) and the Laboratoire de Réactivité et Chimie des Solides (LRCS) in Amiens, France. Pierre worked on the study of multicataionic oxides which demonstrated a pseudocapacitive behaviour, such as perovskites and spinel materials, as potential electrode materials for aqueous electrochemical capacitors in order to improve the volumetric energy density of supercapacitors.
Then, he went to Taiwan in 2019 as a postdoctoral researcher for two years at the Department of Chemical Engineering of the National Taiwan University in Taipei. During these two years, his research was focused on the influence of the oxygen vacancies content of perovskites on their pseudocapacitive properties in mild aqueous electrolyte to demonstrate an anionic charge compensation in this medium. He also worked on a new way to prepare the lithium manganese spinel oxides, a promising electrode material for Li-ion batteries, using an electrochemical-ion exchange process at room temperature.
He joined CIC energiGUNE in 2022 in the Advanced Electrolyte and Cell Integration research group, as postdoctoral researcher on inorganic solid-state batteries.
