초록:
Batteries enable energy conversion between chemical and electrical forms by exploiting thethermodynamic potential difference of charge carriers—metal ions and electrons—betweentwo electrodes: the anodes and the cathodes. Central to this process are charge transferreactions, particularly those occurring at the electrode–electrolyte interfaces. Theseinterfacial reactions play a decisive role in battery performance: they can either triggerharmful side reactions or enable the formation of beneficial interphases. Therefore,understanding the underlying chemistry of these interfacial reactions is primary research toefficiently exploit their versatility. In doing this, analytical approaches such as in-situ characterization on interfacial reactions and post-mortem analysis on reaction productprovide an insight to unveil their nature and guide them to beneficial pathway. This talk willhighlight a series of research focused on studying interfacial reactions in diverse batterysystems including lithium metal anodes, silicon-based anodes, and high-nickel cathodes. A combination of analytical techniques—electrochemical analysis, in-situ characterization,microscopy, and spectroscopy—was employed to elucidate the nature of interfacial reactionsand their versatility in determining the performance of batteries. The insights provided here not only deepen understanding of interfacial phenomena but also offer guiding principles forthe rational design of electrode–electrolyte interfaces in next-generation batteries to achieveenhanced stability, efficiency, and longevity.
