"Polymer-based batteries: From printable thin film to scalable flow batteries"

Energy storage is one of the most crucial elements in the 21st century. Our mobile society requires tailor-made energy storage solutions for a wide range of technologies. Additionally, the demand for stationary energy solutions is steadily growing due to the unsteadiness of renewable resources. In this context, polymeric materials offer great possibilities for the fabrication of energy storage devices – from the small scale (e.g., printable batteries) up to the large scale (e.g., redox flow batteries.[1] The utilization of the organic polymeric material circumvents the usage of toxic/harmful and often critical raw materials (e.g., cobalt, vanadium and other metals). In this context the synthesis and detailed characterization of polymers featuring distinct redox sites based on chinones, nitroxides and other stable radicals (e.g., galvinoxyl radical, phenoxy radicals) will be presented. These materials are used to fabricate polymer-based batteries (Fig. 1). Cathode active materials (e.g., TEMPO based polymers) can be combined either with metallic anodes (zinc, lithium) or with polymer-based anodes. For latter electrodes, galvinoxyls, phenoxy radicals have been applied. The fabrication of these polymer batteries was also accomplished by printing techniques (screen printing, inkjet printing). Moreover, also large scale batteries (i.e. RFBs) can be fabricated on polymer basis. Electroactive polymers have been applied in the electrolyte of RFBs. By this manner the vanadium or other metals can be replaced.

"Research on Bio-based Polymers at NIMTE"

Bio-based polymers are the polymers which are derived from renewable resources (Figure 1). Some research progress on bio-based polymers at Ningbo Institute of Material Technology and Engineering (NIMTE), Chinese Academy of Sciences will be reviewed. The research includes development of heat resistant polylactic acid, soybean based wood adhesives, rosin based polymers, itaconic acid based epoxy resins, and so on. The results indicate that the bio-based polymers show superior properties and have potential to replace petroleum-based polymers.

Prof. Jin Zhu got his Ph.D. from Marquette University in 2001 and did postdoctoral research at Cornell University from 2001 to 2003. He has worked for several American companies from 2003 to 2009 in USA prior to returning China. He is currently working at Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences (NIMTE). He is currently the Director of Institute of Materials Technology at NIMTE. He was selected as a scholar of the “National Thousand Talent Program” in 2012. His research interests are bio-based polymers. He is currently a member of both American Chemical Society and Society of Plastics Engineers. He has transferred two technologies to industry with total amount of 26 million RMB in China. He has published more than 70 research papers. He has 30 patents granted and more than 50 patents pending.
