Welcome to the Takeuchi Research Group!
    Our group conducts cutting-edge research in battery chemistry and technology, involving both Stony Brook University (SBU) and Brookhaven National Laboratories (BNL).  Our research is truly multidisciplinary in nature, involving aspects of Inorganic Chemistry, Electroanalytical Chemistry, Materials Science and Engineering, Theory and Modeling, and Physics.  Our research facilities, constructed in 2012, are specifically designed for our research and are positioned in two locations at SBU and one location at BNL.  Our laboratories are fully equipped with state of the art equipment and laboratories for experimentation in the synthesis and characterization of materials, electrochemistry and electroanalytical chemistry, and battery construction and testing.  Moreover, we have ready access to the impressive array of instrumentation at BNL as well as other national facilities.  Finally, we have active collaborations with theorists and modeling scientists, to combine electrochemistry with theory.
