Symposium A02: New Materials for Next Generation Batteries

Symposium focus: The next generation of energy storage devices requires new approaches to energy storage that take into account numerous variables that include energy density, safety, calendar life, and costs. While lithium-ion systems can meet many of these demands, new chemistries are emerging that can fill these needs and provide a wide array of opportunity for scientists and engineers that does not require the use of conventional material approaches. This symposium has interests in battery chemistries that store energy using non-intercalation chemistries, such as lithium-sulfur (Li/S) and lithium-air (Li/air) as well as cell design strategies, electrode formation, catalysts, and special electrolytes. In addition, non-lithium containing chemistries, including multivalent (Mg, Ca, Al, Zn)-based systems and Na- or K-ion systems are now gaining momentum as alternatives based on factors that include raw materials cost and the ability to use metal anodes to increase energy density. Besides new cathode materials, graphite alternatives have gained significant traction over the past several years. Specifically, new approaches to silicon, phosphorus, and tin anodes have emerged, as has a renewed interest in lithium metal protection strategies. For this symposium, all subjects on these batteries are solicited. Topics should could include the discovery of new active materials and electrolytes, new methods to discover and isolate active materials, and new approaches to electrode and cell design. Additionally, other areas of interest include electrochemical engineering, new and cell designs, cost modeling, new physical and electrochemical characterization methods, and new concepts for these systems are sought.

Symposium A04: Electrolytes, Interfaces, and Interphases

Symposium focus: This symposium intends to highlight the advances made in new electrolyte materials, especially those designed for the new/aggressive chemistries such as Li metal, high voltage and high capacity cathode materials, as well as the fundamental science governing their bulk/interfacial/interphasial chemistries and processes, along with the advanced in-situ/operando characterization techniques and simulation that present new insights. The organizers would like to invite contributions to the following topics:

1. New electrolyte systems and materials;
2. Fundamental understanding;
3. Advanced characterization techniques. (more…)

Symposium I03: Frontiers of Chemical/Molecular Engineering in Electrochemical Energy Technologies: In Honor of Robert Savinell’s 70th Birthday

Symposium focus: In honor of Robert Savinell’s 70th birthday, after more than four decades of research in fuel cells and flow batteries, this symposium is organized to celebrate his achievements. The symposium highlights current and emerging ideas in electrocatalysis, electrolytes, and device design for fuel cells and flow batteries. Topics include molecular-level understanding of small-molecule electrocatalysis (including hydrogen, oxygen, and carbon- and nitrogen-containing molecules such as alcohols, ammonia, urea, carbon dioxide, and others), membranes and electrolytes including additives, nanoparticles, and deep eutectic chemistries, redox-active molecules, and new concepts in fuel cells and flow batteries, with contributions spanning different length scales from molecules to devices. We welcome contributions from both theory and experiment, especially on studies that are designed to bridge molecular-level understanding of electrochemistry to macroscopic electrochemical technologies. The objective is to provide an interdisciplinary discussion forum on the current state and future perspectives in fuel cells and flow batteries, and to celebrate the achievements of Robert Savinell to the field.
