Title: Supercapattery: A New Electrochemical Means for Energy Storage

Date/Time: September 17, 2019  /  13.40-14.30

Place: FENS G032

Abstract: Energy storage is now well recognised in both industry and academia as one of the key technologies to enable safe, secured, and sustainable supply of energy in the post-fossil era. Whilst there are many options for storage of various forms of energy, electricity storage is perhaps the most important for at least two interdependent reasons. Firstly, many renewable harvesting technologies output electricity as the commercial product. Secondly, there should be as few as possible conversion steps in the storage and release processes to minimise energy loss. This presentation will focus on a newly proposed and demonstrated electricity storage device, supercapattery, that combines the performance characteristics of rechargeable batteries (high energy capacity, low power capability) and supercapacitors (high power capability, low energy capacity, and long cycle life). In particular, the performance of supercapattery (cf. the Ragone plot) is correlated to the nanostructured electrode materials (hybrid materials of carbon nanotubes with electronically conducting polymer or transition metal oxides), and device designs developed by the author’s research team in the past years (cf. Refs.1-8). Examples are provided to demonstrate the principle, practice and prospect of this new device.

BIO: George Chen (CChem, FRSC, FRSA, FIMMM) received his Teaching Diploma (Chemistry, Jiujiang Teacher Training College, now Jiujiang University) in 1981, MSc (Physical Chemistry/Electrochemistry, Fujian Normal University) in 1985, and PhD (University of London) and DIC (Physical Chemistry/Electrochemistry, Diploma of Imperial College) in 1992. After postdoctoral research in the Universities of Oxford (1992) and Leeds (1994), he moved to the University of Cambridge (1996), taking up positions of Senior Research Associate (1998), and Assistant Director of Research (2001). In Cambridge, he was awarded the Schlumberger Interdisciplinary Research Fellowship (2000) and elected to Official Fellow (2003) of Darwin College. He joined the University of Nottingham as Reader in 2003, and was promoted to Professor in 2009. He was lecturer of Jiangxi University (1985-1988), and also specially invited professor of the University of Mediterranee (2007) and Wuhan University (2000-2010), and senior academic visitor of Fudan University (2014-2016). In Nov 2014, Prof. Chen started his secondment in the University's China Campus in Ningbo (official name: University of Nottingham Ningbo China, UNNC), and is now leading the Electrochemical Technologies Group (ETG) in both the UK and China Campuses. Since July 2017, he has been appointed Li Dak Sum Chair Professor of Electrochemical Technologies in the UNNC. He also holds honorary/visiting positions in Wuhan University of Science and Technology, Wenzhou University and Shanghai Institute of Applied Physics (CAS). Prof. Chen has undertaken various research projects funded by e.g. the EPSRC, Royal Society, MoST (China), MoSTI (Malaysia), E.ON and Ningbo Municipal Government, with the outputs being documented in over 600 of journal, conference and patent publications. Some aspects of his research are being developed by the industry (e.g. The FFC Cambridge Process by Metalysis, and Supercapattery by E.ON). He is the recipient of numerous awards, including the TMS Reactive Metals Technology Award (2001, 2004), the Royal Society Brian Mercer Feasibility Award (2007), the E.ON International Research Award (2008), the Inman Medal (2014), and Specially Invited Expert (1000 Talent Plan) of Zhejiang Province (2015). The OCRiD of Prof. Chen is 0000-0002-5589-5767. On 30 Jan 2019, Web of Science recorded 229 articles from Prof. Chen with 11219 citations and an h-index of 56, and his record in Google Scholar included 352 publications with more than 14551 citations and an h-index of 65.
