This webinar will touch on electrocatalysts, electrodes, and devices for battery, fuel cell and water electrolyzer. The presentation will focus on material design, nanoparticle synthesis, nano- and microstructure fabrication, and electrochemical evaluation.
Electric vehicles, clean hydrogen production, fuel cells using hydrogen etc. have been in the spotlight due to the demand for eco-friendliness. These technologies are based on electrochemistry, which depends on the performance of electrodes and electrolytes. In particular, electrode materials have greatly advanced due to new synthesis and nanotechnology. However, as these technologies are commercialized, the requirements for material performance and durability have become more complex and prices have increased.
In this presentation, catalyst and electrode material synthesis, electrode fabrication and battery, fuel cell and water electrolysis device fabrication at Seoul National University will be introduced. In the case of batteries, Professor Yung-Eun Sung will introduce nanomaterials for the negative and positive electrodes of lithium secondary batteries and lithium-sulfur batteries, which are in the spotlight as next-generation batteries. In the fuel cell, platinum-based and non-platinum-based nanomaterials for hydrogen oxidation and oxygen reduction will be introduced, and additionally, electrochemical hydrogen peroxide, a type of oxygen reduction catalyst, will be presented. Lastly, a catalyst and electrode structure for producing hydrogen from water for water electrolysis will be presented.
