Research Experience

Dr Song has a multidisciplinary academic background with training and research experiences in energy and power engineering, environmental engineering, chemical engineering, polymer physics, materials chemistry, and nanotechnology.

He received Bachelor's degree in School of Energy and Environment at Southeast University (Nanjing) in 2006. Afterwards, he stayed working with Prof. Rui Xiao on clean energy, catalysis, and low-carbon technologies, and obtained Master’s degree in Energy & Environmental Engineering in 2009. His MSc research involved several projects and led to two Chinese patents and 16 co-author papers published in leading journals in the chemical engineering field, including Combustion and Flame (20102011), the top journal in combustion field.

In October 2009, he joined the Combustion Group led by Prof. John Dennis in the Department of Chemical Engineering at University of Cambridge as a postgraduate student. He developed his independent approach to the synthesis of layered double hydroxides and derived nanostructured metal oxides for chemical looping combustion processes (Energy Environ. Sci. 2013; Nature Communications 2022; Energy & Fuels 2022). The fundamental research led to a better understanding of the materials chemistry of copper-based mixed oxides calcined from the precursors prepared by co-precipitation. Such fundamental research in solid-state oxygen carrier materials has been successfully commercialized via a UK start-up company, Gas Recovery and Recycle Limited (GR2L), and used in argon recycling in solar panel manufacturing, which has generated world-wide impact on clean energy development (Link to Impact Study on Cambridge Website). 

In October 2010, he moved to the Cavendish Laboratory and completed a PhD in Physics with Dr. Easan Sivaniah (now at Kyoto University), and in collaboration with Prof. Eugene Terentjev at the Cavendish Laboratory and Prof. Anthony K. Cheetham FRS in the Department of Materials Science and Metallurgy. He passed his PhD viva in February 2014, and continued as a Postdoctoral Research Associate at the Cavendish Laboratory. During his PhD and Postdoc research, he worked on several types of cutting-edge microporous materials and their applications in membranes for gas separations, notably metal-organic frameworks (MOFs) based polymer composites (Energy Environ. Sci. 2012Nature Energy 2017), polymers of intrinsic microporosity (PIMs) (Nature Communications, 2013;  Nature Communications, 2014Journal of Materials Chemistry A, 2016),  polyamide desalination membranes (Journal of Membrane Science, 2015), and novel porous molecular materials known as porous organic cages (Advanced Materials, 2016Angew. Chem. Int. Ed., 2017) in collaboration with the group of Prof. Andrew I. Cooper FRS at University of Liverpool. some of these research results led to international patents and commercialization through a start-up company (e.g. OOYOO on CO2 capture membranes) as well as partnerships with industry. 

In November 2014, Dr Song joined the Department of Chemical Engineering at Imperial College London in November 2014 to pursue an independent research programme with an award of Imperial College Junior Research Fellowship. He collaborated with Prof. Andrew G. Livingston FREng on microporous polymer nanofilm membranes (Nature Materials, 2016). 

In August 2016, Dr Song started his independent academic career as a Lecturer in the Department of Chemical Engineering and initiated new research in development of ion-exchange membranes for energy conversion and storage. He remains interested in membrane separation research and is one of the principal investigators at the Barrer Centre, a new research centre performing world-leading research in separation materials and membrane technology.  

Since 2016, with the support of department start-up fund and ERC Starting Grant,  he has created an independent, excellent research team and generated breakthroughs in ion-selective membranes for next-generation of redox flow batteries. So far, his group and collaborators (especially, Prof Neil McKeown at University of Edinburgh and Prof Kim Jelfs at Imperial) have developed novel membranes with various polymer chemistries for flow batteries, including PIM polymers with amidoxime groups (Nature Materials, 2020), Tröger’s base (Advanced Science, 2023); carboxylate groups (Advanced Materials, 2022; Nature, 2024, accepted), three-dimensional rigid backbones (Angew Chem, 2022),  sulfonated PIMs (Nature Commun., 2022), sulfonated poly(ether-ether-ketone) (Joule, 2022; Joule, 2024), and sulfonated polyxanthene (Angew Chem, 2020). The concept could also be extended to other aqueous batteries, such as zinc-metal batteries (Angew Chem Int Ed. 2024). PIM membranes could radically improve the performance of advanced batteries where fast ion transport and selectivity are crucial limiting factors. These studies have generated broad academic impact and inspired further research worldwide, as evidenced by the award of Royal Society of Chemistry Materials Chemistry Horizon Prize. Several new polymers stand out as promising candidates that may lead to commercial success, for redox flow batteries, fuel cells, electrolysers, and electrodialysis separation processes. The team has filed one PCT patent on the ion exchange membranes (PCT/EP2024/075338) and won UKRI IAA and ERC proof-of-concept grants to scale up the manufacturing of these membranes. A start-up company is being established to explore the commercialization of the membranes and their broad applications for energy and sustainable processes.
