Abstract: | Batteries play a pivotal role in powering various everyday-use devices, ranging from portable electronics to electric vehicles and renewable energy storage. As the demand for efficient and sustainable energy solutions grows, the exploration of alternative battery materials becomes fundamental. The substitution of lithium with sodium represents an appealing transition due to the abundance of sodium resources, cost-effectiveness, and the potential to address concerns associated with lithium scarcity. This work centers on an in-depth investigation of a polymer-derived SiCN(O) porous matrix employed as an anode for sodium-ion and metallic batteries. The SiCN(O) porous matrix is comprehensively characterized to elucidate its structural and chemical properties. A crucial investigation in this work concerns the optimization of the porosity of the matrix to achieve a reversible Na-plating in the pores of the ceramic. Additionally, an in-depth exploration of the overall storage mechanism within this matrix employs advanced techniques, including operando Raman spectroscopy and dynamic electrochemical impedance spectroscopy. A further study involves the investigation of storage properties of SiOC ceramic in dependence of the material microstructure obtained with slow and ultra-fast heating. Using an ultra-fast furnace enhances both the efficiency and the speed of the pyrolysis process. This thesis aims to design, optimize and characterize an innovative sodium storage system with a porous ceramic as a plating matrix. In parallel novel promising anode materials for Na-Ion batteries have been developed. |
