Abstract :
[en] Developing new materials with high performance, long cycle life while being environmentally friendly and affordable has become a main challenge of our time in promoting energy storage technologies. To successfully meet this challenge, it is essential to find effective methods of optimizing electrode materials. Indeed, it has been demonstrated that purity of the materials, composition, particle size, crystallinity, aggregation, and porosity of the particles are features which determine the electrochemical performance of the battery materials. Furthermore, optimizing the microstructure is a key parameter to obtain advanced performance materials. These parameters are related to the synthesis methods and conditions used to obtain the electrode material Therefore, it is essential to find a suitable and versatile synthesis method to prepare the active electrode material. Spray-drying is an easy method to control the morphological properties of the electrode materials. In addition to its versatility, spray-drying method has the advantages of being cost effective, easily up-scalable and allow obtaining highly homogenous composites powders 1. This makes it a method of choice for synthesizing complex (multi-component) powders with a high homogeneity, characterized with a very good electrochemical properties. In this presentation, we will show a summary of our recent results obtained in battery field using spray-drying method at GREEnMat laboratory. Spray-drying method was used to synthesize different polyanionic compounds as active cathode materials for Na/K-ion batteries (such as Na2FePO4F, Na3V2(PO4)2F3 and K3V(PO4)2 and K3Fe2(PO4)3) and also to enhance their electronic conductivity by addition of carbon sources 2-4. Spray-drying was also used as shaping method in the case of nano-structured silicon recovered from solar panel as anode materials for Li-ion batteries. One of the main problems with silicon anode material is the volume expansion during cycling. The spray-drying method has allowed the structuration of the silicon in order to reduce the volume expansion and thus offer a long cycling life 5. The influence of the synthesis method and the addition of carbon sources on the structural, morphological, electrochemical properties of the electrode materials has been rigorously analyzed by combining different characterization techniques such as: XRD, SEM and TEM, Mössbauer spectroscopy (for iron containing material), BET, Cyclic Voltammetry, Galvanostatic cycling etc.References : 1- Vertruyen, B.; Eshraghi, N.; Piffet, C.; Bodart, J.; Mahmoud, A.; Boschini, F.
