Institut de Chimie de la Matière Condensée de Bordeaux

Our activity consists in applying a Solid-State-Chemistry strategy to optimize existing materials or propose new materials for batteries, microbatteries and supercapacitors. Investigations are focused on Li and Na transition metal oxides, on compounds with polyanionic frameworks, on electronically conductive cobalt oxides and on thin film materials for microbatteries. In addition to more « classical » structural and physical characterizations available at ICMCB, the group has specially developed electrochemical characterizations,

X-ray diffraction (in particular in situ or operando), electron microscopy, as well as NMR applied to paramagnetic compounds, with a theoretical approach aiming at better understanding the latter. We therefore globally aim at better understanding the materials and their alkali-metal insertion/deinsertion properties, in order to focus investigations on preparing ever better materials in terms of electrochemical energy storage or of remarkable properties.
