The Journal of The Electrochemical Society is publishing a virtual focus issue in connection with IMLB 2022, hosted in Sydney Australia. This issue is only open to participants of IMLB 2022 who presented therein (invited talks and posters). Review, critical review, perspective, methods, communication, and original research articles are welcomed.
IMLB 2022 is the premier international conference on the state of lithium battery science and technology, as well as current and future related battery systems for application in transportation, industry, grid storage, aviation, aerospace, biomedical, and other promising sectors.
Manuscripts submitted to this issue undergo the normal rigorous review process used for JES, with papers expected to meet the customary high scientific and technical standards for which this journal is known.

During battery (dis)charging, lithium (de)intercalation in electrodes is usually spatially non-uniform across multiple length scales. Such a phenomenon is a major impediment to battery performance and life as it causes energy under-utilization and induces over-(dis)charging, etc. While reaction heterogeneity is often attributed to mass transport limitation, this talk highlights the important roles of thermodynamic factors including elastic energy and phase transformations, the understanding of which is important for the development of mitigation strategies. Through combined modeling and characterization, how stress could destabilize the lithium (de)lithiation front in single crystalline and polycrystalline intercalation compounds is elucidated. Also, a fundamental driving force for dendrite growth on the lithium metal anode during electrodeposition is provided. Stress relief thus offers a promising approach to improving reaction uniformity at the particle level. At the cell level, the reaction distribution that within the porous electrode is strongly influenced by how the electrode’s equilibrium potential varies with the state of charge, is discovered. Two types of prototypical reaction behavior emerge from common electrode materials with significant impact on the thick electrode performance. This finding leads to an efficient analytical model for optimizing battery configurations in place of common battery cell simulations. (more…)
The long-anticipated fourth edition of Electrochemical Systems by John Newman and Nitash P. Balsara is now available.* The fourth edition updates all of the chapters, adds content on lithium battery electrolyte characterization and polymer electrolytes, and includes a new chapter on impedance spectroscopy. Topics covered include electrochemical theories as they relate to the understanding of electrochemical systems; the foundations of thermodynamics; chemical kinetics; transport phenomena including the electrical potential and charged specials; and how to apply electrochemical principles to systems analysis and mathematical modeling.
ECS thanks Drs. John Newman and Nitash Balsara, authors of Electrochemical Systems Fourth Edition, for generously speaking with us in December 2020.

“Good enough” are just words in his last name, but not ones John B. Goodenough seems to live by. The 97-year-old, widely referred to as the “father of the lithium-ion batteries,” continues to awe the battery field. According to IEEE Spectrum, the 2019 Nobel Prize winner recently co-developed a rapid-charging, non-flammable, glass battery.
The high capacity battery charges in “minutes rather than hours,” according to Maria Helena Braga, professor of engineering at the University of Porto in Portugal, who worked with Goodenough to develop the solid state lithium rechargeable which uses a glass doped with alkali metals as the battery’s electrolyte. In addition, the solid state electrolyte is not flammable and preforms in both cold and hot weather. (more…)
