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…)

This webinar discusses the latest strategies in making customized carbon electrodes for neurotransmitter detection. Various carbon nanomaterials are reviewed, including carbon nanotube yarns and carbon nanospikes. In addition, we examine how 3D printing can be used to make small, custom geometry carbon electrodes.
The Electrochemical Society hosted Prof. Jenny Pringle’s live webinar, “The Development of New Ionic Electrolytes for Energy Storage Devices” on April 21, 2021. Her answers to questions that followed the presentation are provided below.
NOTE: Registration is required to view the webinar.
Prof. Jenny Pringle works in the Institute for Frontier Materials at Deakin University, Australia, as a chief investigator in the ARC Centre of Excellence for Electromaterials Science (ACES) and the ARC Industrial Transformation Training Centre “StorEnergy.” She received her undergraduate degrees and PhD at The University of Edinburgh, Scotland, before moving to Monash University, Australia, in 2002. From 2008-2012, she held an ARC Queen Elizabeth II Fellowship investigating the use of ionic electrolytes for dye-sensitized solar cells. Pringle moved to Deakin University in 2013. There she leads research into the development of new ionic liquids and organic ionic plastic crystals for applications including thermal energy harvesting, gas separation membranes, and lithium and sodium batteries.
