Eddie Shanqing Zhang教授简介：
Prof. Eddie Shanqing Zhang obtained his PhD degree in electrochemistry in 2001 at Griffith University, Australia. Since then, he has been working on synthesis, modification, characterisation of nanostructured materials for sensing, energy conversion and energy storage devices. As an inventor, Eddie has developed a series of patented and commercialized photoelectrochemical sensors for environmental monitoring based on the functional nanomaterials. He was awarded Australia Research Council Future Fellow in the period of 2009-2013. Currently, Eddie is leading his group in research on energy conversion, energy storage and environmental monitoring. Functionalizing binders for low cost, sustainable and high capacity energy storage devices is a newly established research direction led by Eddie.
摘要：
Sustainable, highly efficient and low cost energy storage devices are the ultimate solution to tackle the problems related to the depletions of fossils fuels, exhaustion of natural resources and deterioration of environment. Currently, polyvinyldifloride (PVDF) remains the dominant binder position in lithium ion battery (LIB) and supercapacitor industries. Such a binder has several drawbacks, e.g., the involvement of the use of costly and toxic organic solvents, the requirement of strictly non-water electrode assembly environment and most importantly, the inability in high power high energy density electrode materials such as silicon anodes, tin anodes and sulfur cathodes. In this seminar, a few strategies are introduced to address these issues. In particular, the adoption of aqueous binders (including natural binders), the design of new generation of binders by incorporation of various functional groups onto the binders to strengthen the mechanical properties (such as binding strength, hardness and ductility) and enhance ionic and electronic conductivity, establish new chemical bonding between the binder and electrode materials (such as sulfur) and addition of new functionality such as self-healing properties are extensively reviewed for their application in LIBs, lithium-sulphur batteries and sodium ion batteries strategy of unveiling and exploring the function of binders will facilitate the development of new generation of energy storage device for large scale application in electrical vehicles and smart electricity grids.
