Nanostructured Electrodes Via Electrostatic Spray Deposition for Energy Storage System

Energy storage system (such as Li-ion battery and supercapacitor) is an important technology in today’s society, and has been widely used as the power source for portable electronics, electrical vehicles and hybrid electrical vehicles. Lots of research has focused on improving its performance, however, many crucial challenges need to be addressed to obtain high performance for further applications. Recently, an electrostatic spray deposition (ESD) technique has attracted great interests to satisfy the goals. Due to its many advantages, such as simplicity, cost-effective setup, non-vacuum, low temperature deposition conditions, good control for tailoring film composition and morphology, and high deposition efficiency, the ESD technique shows very promising prospects compared to other conventional deposition techniques. It provides a simple but versatile strategy for generating single or multi-component materials with varied morphologies, such as sponge-like, dense, porous and fractal, etc. It is belived that controling structures is an effective way to optmize electrochemical performance in reagrding volume change buffering, short ion diffusion passway, etc.. In this talk, our recent research outcomes related to the ESD derived anodes for Li-ion batteries and supercapacitors, such as graphene, Li₄Ti₅O₁₂, Sn, SnO₂, NiO, Fe₂O₃, Co₃O₄, CoO, and Cu₂O, etc. Will be summarized and discussed.
