Arjun Kumar Thapa, PhD, is research scientist at the Conn Center, where he is focused on synthesis and development of high capacity cathode and anode materials for Li-ion, Li-Air, Li-S, Na-ion batteries and capacitors. He is the R&D Manager for the center’s Battery Research Laboratory.


He received his doctorate in Material Science & Engineering from Saga University (Japan) in 2007 under Prof. Masaki Yoshio. His research was focused on synthesis and development of cathode materials for Li-ion batteries and megalo-capacitance capacitors. He also holds an MS in Material Science & Engineering from Saga University (Japan) in 2004. He conducted research on synthesis of halogen doped o-LiMnO2 cathode materials for lithium-ion batteries and their performance at elevated temperature.


Arjun received his M.Sc. in Physical Chemistry from Tribhuvan University (Nepal) in 1999. As a Postdoctoral Fellow at Advance Research Center in Saga University (2007-2008), he worked on novel high-energy density capacitors in collaboration with Ishihara Sangyo Co. Ltd. Japan. In 2008, he joined in the group of Prof. Tatsumi Ishihara at Kyushu University (Japan) as a Global COE Postdoctoral Fellow, where he focused on synthesis of mesoporous metal oxides catalyst for Li-Air batteries for the New Energy for Industrial & Technology Development Organization (NEDO Grant), Japan. He was project lead for Li-Air battery research group in Prof. Ishihara’s lab from 2009 to 2011. He joined Conn Center in 2011 as a Senior Research Associate.


He is author/co-author of over 30 original research papers, one book chapter in capacitor and currently one patent pending. As a battery researcher, he has over 14 years of research engineering experience in material science/battery development for different synthesis process and application in energy storage systems in coin cell, pouch cell, electrolytes preparation, In-situ XRD, dual-carbon battery, and hybrid capacitors.
