Abstract Scope |
Additive Manufacturing opens the way towards the preparation of intricate and shape-conformable batteries with enhanced specific surface area and improved electrochemical performance in term of power. Current efforts are focused on the 3D printing of sodium-ion battery negative electrodes by means of the Digital Light Processing (DLP) technology. As material feedstock for the DLP Admaflex 130 printer, a highly-loaded composite photocurable resin containing titanium dioxide and conductive additives is prepared. An optimization of the printing and thermal post-processing parameters is performed with a view to ensure adequate mechanical integrity/robustness of the electrodes as well as suitable electrochemical performances. Preliminary results suggest that the introduction of complex electrode structures with precisely controlled porosity leads to improved liquid electrolyte impregnation, better sodium ions diffusion and enhanced specific capacity values. This talk will address the structure-property relationship of 3D printed titanium dioxide/conductive carbon in terms of their mechanical, structural, and electrochemical properties. |
