Title: From Graphene to Graphene-Enabled Batteries for EV Application: A 17-Year Journey
Speaker: Prof. Bor Z. Jang, Global Graphene Group, 1240 McCook Ave, Dayton, OH 45404.
Dr. Jang is a pioneer in the field of graphene technology, including graphene manufacturing and applications. Dr. Jang and his business/research partner, Dr. Aruna Zhamu, co-founded Angstron Materials, Inc. (AMI) in 2007 and Taiwan Graphene Co. (TGC) in 2013 for scaling up production of graphene and graphene oxide. AMI/TGC is currently world’s first and largest producer of single-layer graphene oxide and graphene nano-intermediates. Over the past 15 years, graphene has become one of the most exciting topics in the field of nanotechnology. The research team led by Dr. Jang has contributed to the field of graphene science and technology in many aspects. He is a co-inventor of 550+ US patents (issued, pending and applied for), out of which 300+ patents are related to graphene and 250+ related to supercapacitors, fuel cells, and batteries. There are currently 100+ PCTs filed (international patent application). Dr. Bor Jang received his MS and PhD degrees in Materials Science from MIT. Dr. Jang is a former Dean of the College of Engineering and Computer Science at Wright State University and a former Fulbright Scholar and Visiting Professor with the University of Cambridge (1991-1992). Abstract: After discovering/inventing graphene materials in 2002, Dr. Jang’s team has been working on the mass production and commercialization of graphene and development of major graphene applications. As a graphene inventor and entrepreneur, Dr. Jang will offer some personal perspectives on the rapidly emerging graphene industry, emphasizing the opportunities and challenges in commercializing graphene materials and products. The technical and commercial challenges experienced by graphene producers will be highlighted. For instance, a significant challenge is the notion that graphene is a unique material that requires different processes to bring out the most desirable characteristics for a particular application. In other words, different processes are required to produce different types of graphene materials for different applications in different market sectors. There are also technical, economical, and regulatory issues that must be addressed in order for the large-scale production of affordable graphene materials to be fully realized.
This will be followed by a discussion on some of the potential and realized applications of graphene materials, including graphene-enabled batteries for EV applications. Dr. Jang’s research team was the first to invent graphene-containing anode and cathode materials for lithium-ion cells. The team has also developed graphene-based lithium metal anode protection technology, which is essential to the emergence of all lithium metal secondary batteries such as Li-S, Li-Se, Li-air, and other rechargeable batteries featuring a lithium metal anode. Also developed is the graphene-protected sulfur cathode for overcoming the challenges that have thus far impeded full-scale commercialization of Li-S cells, including shuttling effect, low sulfur conductivity, low sulfur content and low sulfur utilization efficiency.
