Welcome to the Marschilok-Takeuchi Research Group!
Our goal is to change how the world uses and stores energy to benefit society and the environment.  Access to clean energy directly impacts quality of life.  Ability to store energy and release it on demand is necessary to implement renewable energy sources on a wide scale.  Our group investigates the science and technology of power sources that will be enabling technologies for diverse and demanding applications, such as lifesaving implantable medical devices, electric vehicles and grid level storage.    

Our research is multidisciplinary in nature, drawing on skill sets from Inorganic Chemistry, Electrochemistry, Physical Chemistry, Analytical Chemistry, Materials Science, and Chemical Engineering.  Our group conducts synthesis, characterization, measurement and analysis leading to cutting-edge research in battery chemistry and technology, involving both Stony Brook University (SBU) and Brookhaven National Laboratories (BNL).  Our research facilities in two locations at SBU and at BNL are specifically designed for experimentation in the synthesis and characterization of materials, electrochemistry and electroanalytical chemistry, as well as battery construction and testing.  Finally, we have active collaborations with theorists and modeling scientists, to combine experimentation with theory.

            The Center For Mesoscale Transport Properties 2014-2022
A unique aspect of our facilities is our Energy Frontier Research Center (EFRC), The Center for Mesoscale Transport Properties, funded by the Department of Energy (DOE).  Our center's first four years (2014-2018) were highly successful, and we received an award for additional four years through an open re-competition process (2018-2022).  There are a total of 46 EFRCs in the U.S. and four focus on electrochemical energy storage. These centers are multidisciplinary collaborations among universities, national laboratories, non-profit organizations and for-profit firms that investigate matter control at the quantum, atomic, and molecular levels for energy applications.
