Arjun Thapa

R&D Manager, Battery Research, Conn Center for Renewable Energy Research

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.
