This research area explores the potentialities of original synthetic and analytical tools for the preparation and characterization of divided materials, organized or textured in order to improve the (electro)chemical reaction properties. During the period 2011-2016, we have thus: i) developed the use of bacteria for bio-assisted preparation in ambient conditions of highly textured materials (a-Fe₂O₃, FePO₄) ii) used a potentiometric method and new electrochemical cells to determine the interface energy of the electrodes and the evolution of some of their characteristics during cycling, iii) studied the nano-containment of H2 storage materials and electrode materials and iv) continued the use of electrochemistry as a tool for synthesis and characterization.

•     Bio-assisted approaches for synthesis and texturing electrodes
•     Electrochemical measurements of surface energy and measuring cells
•     Nano- containment of H2 storage materials and electrode materials
•     Electrosynthesis (electrodeposition) of electrode materials for 3D batteries, active material/collector interfaces  improvement, understanding of the (electro)chemical mechanisms.
