  • 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

  • JCESR Scientific Sprints - Speed through Collaboration

    JCESR supplements its traditional project management approach with scientific “Sprints.” Sprints take a single question from JCESR’s catalog of prioritized scientific challenges and dedicate a small, multidisciplinary team of 5-15 members to answer it, enabling us to move forward more rapidly in our research. Sprints empower early-career scientists to show their leadership qualities in the Sprints they lead. Once a Sprint is completed, the outcome is documented within JCESR and shared with the research community. The resulting new knowledge then informs and inspires subsequent research challenges.

  • JCESR Scientific Sprints - Better Polymers for Better Batteries

    JCESR supplements its traditional project management approach with scientific “Sprints.” The sprint described in this video involved a multidisciplinary team from Argonne, the University of Illinois at Urbana-Champaign, Massachusetts Institute of Technology, and the University of Michigan. As they studied how polymers in solution can … Read More

  • Sprints Accelerate Research

    In October 2014, we introduced “Sprints” to accelerate research and meet our goal of developing two battery prototypes, one for transportation and the other for the grid. Each Sprint begins with the identification of a critical scientific question for prototype development that must be answered within a few month timeframe, and the formation of the right team of scientists and engineers to answer the question. This arrangement has resulted in increased interaction across organizations. 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
