  • Scientific Sprints: Speed Through Collaboration

    As an innovative twist on traditional project management, JCESR conducts “Sprints,” small teams of dedicated researchers formed to solve a select research challenge within 1-6 months. Using the Sprint approach, JCESR takes a single question from our catalog of prioritized scientific challenges and dedicates a small, multidisciplinary team of 5-15 members to answer it. Read More

  • The Electrochemical Discovery Laboratory

    The Electrochemical Discovery Laboratory (EDL) — a key JCESR discovery tool located at Argonne — synthesizes high-quality materials for testing in beyond-lithium-ion batteries and characterizes their properties with state-of-the-art analytical techniques. Read More

  • The Electrolyte Genome Project

    Traditional chemistry relies on intuition and experience to select a few materials that might work well for new electrolytes. The Electrolyte Genome streamlines this process by evaluating thousands of materials by simulation on the computer and choosing the most promising few for synthesis in the laboratory. Read More

  • Water as a Catalyst – Improving how Batteries Function

    Anyone who has ever dropped a cell phone in the sink will tell you that electrical devices and water do not go together. However, a new study has shown that conventional wisdom may not hold on the molecular scale in some beyond-lithium-ion batteries. Read More

  • Techno-Economic Modeling -- Building New Battery Systems on the Computer

    JCESR is applying techno-economic models to project the performance and cost of a wide array of promising new battery systems before they are prototyped. The results from techno-economic modeling establish performance “floors” for discovery science teams looking for new anodes, cathodes, and electrolytes for a beyond lithium-ion battery, identifying those with the potential to meet JCESR’s goal and rejecting those unlikely to be effective.

  • Fitting the Lithium-Sulfur Battery with a New Membrane

    The lithium-sulfur battery has higher energy storage capacity and lower cost than lithium ion. But there is a serious stumbling block. Polysulfides form in the cathode during battery cycling and pass through the membrane to contaminate the lithium metal anode. This results in a rapid decline in performance. JCESR researchers appear to have found a solution to the problem – the “polymer of intrinsic microporosity” (PIM). Read More

  • Technology

    JCESR’s focus has changed to building transformational materials from the bottom up, atom-by-atom and molecule-by-molecule, where each atom or molecule plays a prescribed role in producing the desired overall materials performance. We could not have done this 10 years ago when the advanced scientific tools … Read More

  • Team Approach

    JCESR is a collaborative team of engineers and scientists with very broad backgrounds. In the battery space we are now facing challenges that required a multidisciplinary approach that no single group can achieve. Made up of 18 partner institutions, JCESR’s diversity and the opportunity for … Read More

  • Renewed Focus

    JCESR has had a very successful first five years. The personal relationships we’ve formed now enable us to move forward with even more momentum. Recently, the team of more than 150 came together for its first full program meeting since renewal. As stated by the … Read More

  • Simulation and Measurement of Water-induced Liquid-liquid Phase Separation of Imidazolium Ionic Liquid Mixtures

    Computationally predicted liquid-liquid phase equilibrium confirmed by experimental measurements. Read More

  • Unified Platform for Ion Transport in Inorganic Glasses, Polymers and Composite Solid Electrolytes

    In this review paper, ion transport parameters in seemingly different solid electrolytes – glasses, polymers, and composites - were presented on a unified platform. Read More
