About the Seminar:

Lithium-ion batteries are an omnipresent aspect of the modern world and are found in the majority of consumer electronic devices. Although lithium-ion batteries can store a lot of charge, this technology is limited in the power it can provide and requires expensive and isolated feedstock materials. Alternative battery technologies like 3D batteries and sodium-ion batteries are good replacements for lithium-ion batteries due to the good power density of 3D batteries and cheap feedstock materials for sodium-ion batteries. Concerning both 3D batteries and sodium-ion batteries, it is incredibly important to understand how interfacial interactions and phenomena affect the performance of these systems. The work presented herein highlights advances made in 3D batteries and the areas in which they need to progress, the functionality of protective cyclized-polyacrylonitrile (cPAN) coatings on antimony-based anodes in sodium-ion batteries, and a beginners guide to understanding interfacial interactions via electrochemical impedance spectroscopy (EIS).
