In order to rationally design improved materials for electrochemical applications, we need to understand the origins of electrochemical performance and instability in active materials. This is true for established electrochemical technologies (e.g. lithium ion batteries and supercapacitors), as well as for emerging electrochemical applications (e.g. electrochemical desalination and separation processes). Understanding the performance and instability of active materials during electrochemical operation is a formidable task given the complexity of the physics involved and dynamic material structures present under applied bias. In this poster, I discuss the use of experimental and theoretical techniques to understand where we have been, and help decide where we need to go to improve material performance for electrochemical applications. Specifically, I aim to leverage my background in nanomaterials synthesis and characterization, ab initio materials modelling, and in operandomaterials characterization to improve existing battery materials and develop new materials for emerging applications including anion intercalation electrodes for electrochemical desalination and high rate pseudocapacitive electrodes for grid-level energy storage.
