EDL: Discovering Electrochemistry at Atomic and Molecular Levels

Scientific Achievement

Established in situ Electrochemical Discovery Lab (EDL) for systematic studies of wet and dry interfaces for materials-by-design and electrolytes-by-design at atomic and molecular levels

Significance and Importance

  • Systematic synthesis and characterization of high purity electrolytes, electrodes and interfaces under controlled conditions reveals electrochemical trends in activity, selectivity and stability
  • Interactive collaboration with theory and simulation in Electrolyte Genome and Materials Project
  • Spans single crystal model systems and practical battery materials and phenomena


  • Synthesis of high purity ether-based electrolytes with water content less than 1 ppm
  • Discovered that 10 ppm of water catalyze the lithium peroxide reaction, suggesting that trace amounts of water are key players in other battery chemistries

Work performed at Argonne National Laboratory (JCESR managing partner) V. Stamenkovic, S. H. Chang, J, Connell, B. Genorio, J. Staszak-Jirkovsky and D. Strmcnik

    This is an invited perspective aiming to help researchers new to the field of battery research to circumvent certain recurring misconceptions and inaccuracies in the current battery literature. It covers the electrolyte ideality and practical situation in batteries, the difficulty in accurately determining ion transference … Read More

  • Quantifying Lithium Ion Exchange in Solid Electrolyte Interphase (SEI) on Graphite Anode Surfaces

    By using Li isotopic labelling of SEIs and electrolytes followed by time-of-flight secondary-ion mass spectroscopy and solid-state NMR analyses, we found that the majority of Li+ “immobilized” in the chemical ingredients were exchanged after 1 SEI formation cycle. Ion exchange by diffusion based on concentration … Read More
