  • 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

  • A Message from JCESR Director George Crabtree

    Despite the coronavirus challenges, JCESR continues to push the frontier of energy storage science as we telecommute from home, like much of the nation. We are turning our attention to computation, data analysis and paper writing which continues at a normal or higher pace, enabled … Read More

  • You’re invited: Idaho National Laboratory and JCESR webinar on energy storage (March 18 )

    Electrification is changing the energy landscape of the Mountain West region. While energy storage remains a key enabler to this transformation, infrastructure upgrade and supply chain development will be a key driver for this new economy. Join us on March 18 for a webinar where we’ll … Read More

  • Direct Nano-Synthesis Methods Notably Benefit Mg-Battery Cathode Performance

    A novel Mg cathode material – CuCo2S4 – was identified as a conversion material where direct nano-synthesis was required to provide the best electrochemical performance and deliver 350 mAh·g-1 at 60 °C, a capacity nearly double that of ball-milled material with similar dimensions. Read More

  • Quantifying Capacity Losses due to Solid Electrolyte Interphase Evolution

    We quantified the capacity loss originating in solid electrolyte interphase (SEI) growth during each cycle and extracted the proportionality constant for SEI growth following a parabolic growth law. This continuous SEI growth contributes to the increasing overpotential, leading to capacity fading at a given constant … Read More

  • On Lifetime and Cost of Redox-Active Organics for Aqueous Flow Batteries

    In this viewpoint, we recommend methodology for (1) testing aqueous organic flow batteries to better understand the fade mechanisms and failure modes, and for (2) techno-economic assessment of these batteries that incorporates the costs associated with electrolyte decay and replacement to articulate a feasible design … Read More
