In recent years, Chinese and Australian researchers have maintained close and extensive cooperation in the fields of material science, physics, chemistry, biology and the others. The close international cooperation between the two sides has yielded a large number of important research results and actively promoted the development of relevant scientific fields.

China-Australia Quantum Science and Advanced Materials Series of Lectures are sponsored by China-Australia Scholars Federation and held by Sui Tong Science Cloud. This cutting-edge academic communication aims at promoting academic exchanges and cooperation between China and Australia in quantum science, advanced materials and other related fields.

These series of lectures, as a great opportunity, will provide a platform for further communication between domestic and foreign researchers. We will invite many renowned Chinese and Australian scholars and researchers to share the latest research results, disseminate scientific knowledge and discuss the research direction.

讲座摘要

在多年的材料研究中，新材料的设计和加工策略，以及与其相对应的研究方法都获得了重大进步和突破。在本次报告中，我将特别强调利用多功能材料组合策略，设计并获得新型能源材料，并利用协同效应获得优异的性能。这些策略包括利用碳涂层与能带工程结合的方式改变材料的电子性质；针对能源材料设计并实现形貌尺寸的通用控制方法；利用物理约束与催化作用相结合的设计理念，控制金属硫电池中多硫化物的损耗；利用应变工程增加催化剂的反应活性位点数目；利用材料可控增减工程方法实现纳米材料的可控制备；利用多维度操作以实现电子性质和离子性能的优化;利用电子杂化实现储能材料的高反应活性。在上述工作中，我们发现表界面科学与工程无论从理论还是应用的角度，都是能源材料设计和加工中最关键的环节。我们还意识到大多数研究的局限性都是由研究的投入和产出之间的差异所决定的。同时，研究产出和商业效益之间存在的矛盾和巨大差距也需要在产学研过程中加以解决。在这个方面，我的团队通过开发先进的电池管理系统、设计和建造用于驱动矿车的电池组等产学研项目，将实验室的研究成果成功转化为工业应用，为产学研一体化树立了独一无二的榜样。

Abstract

Significant advances in development of strategies and approaches on novel materials design and processing have been made. Here we particularly highlight the advantages of combination of multi-functionalities to achieve synergetic effect on energy materials performance towards applications. These include combination of carbon coating with band engineering for alteration of electronic properties; universal general approach for morphology control; combination of physical confinement with catalytic effect to control polysulphide loss in metal sulphur battery; Multiple strain engineering for increase of reactive sites in catalysts; Additive & subtractive engineering for controlled growth of nanomaterials with designed size, shape and composition; Multiple dimension manipulation to achieve optimised electronic and ionic properties; Hybridisation at materials, structure & device level to achieve high reactivity in energy storage materials. Among these the interface/surface science and engineering is the most critical element for energy materials design and processing at both fundamental and applied level. Most of the research is limited within the block of research inputs to research outputs while there is a huge gap between research outputs and commercial benefits which need to be addressed. Scaling-up remains as a great challenge to facilitate industry transformation processes from laboratory to real world applications. The design and construction of battery pack driven mining veicles through development of advanced battery management system by UOW team sets unique example for transfering lab success to industry applications.
