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

Understanding fluorine-free electrolytes via small-angle X-ray scattering
We compare the solvation phenomenon of sodium tetraphenylborate (NaBPh4) salt dissolved in organic solvents of propylene carbonate (PC), 1,2-dimethoxyethane (DME), acetonitrile (ACN) and tetrahydrofuran (THF) by SAXS/WAXS measurement and MD simulation. Read More

Navigating the Minefield of Battery Literature
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

A Sobering Examination of the Feasibility of Aqueous Aluminum Batteries
We revealed the first compelling evidence for a dynamic octahedral solvation structure around Al3+ dominated by labile water and OH-, without Al-OTf contact ion pairs, at high salt concentrations. High proton activity is observed in transport and electrochemical measurements which relates well with the proposed … Read More

Ion Migration Mechanisms in the Sodium Sulfide Solid Electrolyte Na3-xSb1-xWxS4
The atomic-scale mechanisms that underlie the exceptionally high ionic conductivity of Na3-xSb1-xWxS4 are elucidated. The conductivity is well explained by a combination of vacancy-related effects and a strong overlap of cation vibrational modes with anion librations. Read More
