PolyU research projects in advanced manufacturing, new materials, and new energy have been awarded funding through the Research, Academic, and Industry Sectors One-plus Scheme (RAISe+), as announced by the Innovation and Technology Commission (ITC) of the HKSAR government recently. 

The funding will expedite the commercialisation of these projects, enabling our researchers to develop innovative solutions, forge stronger industry partnerships and ultimately translate their research outcomes into real-world impact.  

The two awarded projects showcase the University’s dedication to promoting excellence in research and innovation, while emphasising the translation of scientific advancements into practical applications for the benefit of society.

1/ Energy-Efficient Liquid Cooling System for Data Centres (Advanced Manufacturing)

Led by Professor Wang Zuankai, Associate Vice President (Research and Innovation), Kuok Group Professor in Nature-Inspired Engineering, and Chair Professor of Nature-Inspired Engineering in the Department of Mechanical Engineering, this project aims to address the substantial energy consumption and environmental impact caused by cooling systems in data centres. The team’s innovative Energy-Efficient Liquid Cooling System (ELCS) utilises nano-engineered surfaces and phase change cooling principles. By achieving nearly zero-energy cooling, ELCS can significantly reduce energy consumption while maintaining high heat fluxes, outperforming traditional methods. The integration of AI and the Intelligence of Things further enables real-time monitoring and optimisation of the system's thermal performance.

2/ Pilot and Mass Production of Next-Generation Composite Current Collectors for Mobility and Energy Storage Batteries (New Materials and New Energy)

Led by Professor Zheng Zijian, Chair Professor of Soft Materials and Devices in the Department of Applied Biology and Chemical Technology, the project aims to develop an ultrathin, ultralight, flexible and durable composite film to serve as a current collector (CC) for Li-ion batteries (LIBs) and future solid-state Li batteries, aiming at boosting their energy density. 

The composite CC developed by the team is 80%-85% lighter and 65%-80% thinner than current metal foils, with a cost reduction of 40%-60%. Furthermore, compared to metal foils, the composite CC better maintains electron and thermal conductivity, chemical and electrochemical stability, and compatibility with various electrode materials. This breakthrough innovation increases the gravimetric energy density and the volumetric energy density of LIBs, contributing to advancements in energy storage technology. 

The RAISe+ Scheme, inaugurated in 2023, provides matching funds to research teams from universities funded by the University Grants Committee which demonstrate strong potential to evolve into successful startups. Each approved project will receive funding support ranging from HK$10 million to HK$100 million. PolyU's successful projects in this initiative highlight the University's research prowess and commitment to driving innovation and technological advancement in Hong Kong and beyond.
