Recent deployment of electrochemical devices in space, such as on the International Space Station and on Mars-based rovers, has highlighted the potential for using electrochemical processes and devices for critical space functions such as life support, in situ resource utilization, and vital probes for extraterrestrial exploration. The uniqueness of extraterrestrial environments such as microgravity, extreme temperatures, and the usual need for autonomous operation raises both fundamental questions about electrochemical processes and application challenges for device design. Electrochemical power with robust fuel cells, energy storage with batteries, and electrolyzers for production of metals, fuel and oxygen production present promise for increasing the viability of self-sustaining spaced based activities. This symposium invites research and developers to present recent advances in electrochemistry in and for space applications in a wide array of topics including but not limited to the following:

(1) fundamental impacts of extraterrestrial environments on electrochemical processes;

(2) in situ resource utilization through conversion of lunar, Martian, and asteroid materials into propellants, clean water, oxygen, and structural or functional materials/devices;

(3) electrochemical power sources to survive harsh environments of space;

(4) energy storage for power management in various extraterrestrial environments;

(5) sensors for chemical and radiation detection and for environmental and human health monitoring in space applications;

(6) electrochemical processes for environmental controls in extraterrestrial environments

This interdisciplinary symposium will bring together speakers from across a broad range of disciplines to discuss advances in research and development for electrochemistry in space. This symposium will also address how the extraterrestrial environments impact electrochemical processes as well as component design and operation. We want to facilitate broad interdisciplinary conversations through this symposium.

The ECS Europe Section is organizing a special day-long event aimed at early career professionals in electrochemistry and materials science hailing from the geographical region of Europe. The purpose will be to facilitate connections between scientists and engineers in the field, introduce calls for research grants, in particular those requiring teams from several countries, allow time in between presentations to learn about participant’s research and projects and communicate similarities, differences, concerns and anxieties in seeking to do research across the countries of Europe.

Several keynote speakers will be invited, in particular representing grant institutions or international research consortia. These experts will be available during deliberately planned extended coffee breaks. While it is assumed that participants at the symposium will choose other symposia in their own technical interest area for their full papers, informal opportunity will be offered to young and early career researchers during the workshop period to highlight in a 2-3 minute "elevator speech" their own work. Young and early career participation is suggested to mean 35 years or younger OR within 5 years of embarking onto new topic or career track. When submitting to other Gothenburg symposia, please indicate your desire to also be included for consideration in Z03. The ECS Europe Section will hold its traditional reception one of the meeting evenings. All participants in this symposium and workshop are invited to attend.

The symposium focuses on “outside of the box” approaches and developments in materials, components, and systems for addressing the grand challenges in the area of electrochemical energy systems. Of particular interest are innovations in materials, methods, designs, and analytical strategies for realizing sustainable and efficient energy conversion, storage, and transmission, not limited to fuel cells, batteries, capacitors, PEC, and photovoltaics. Contributions to new methods to characterize, model, and analyze interfaces, cell, and system performances in aqueous and non-aqueous environments are of particular interest. The symposium features oral presentations, posters, and invited talks from subject-matter experts.

As a part of this symposium under “Ideas, Interchange & Initiative” (Triple I), abstracts can be submitted based on premature and unexplainable results. The aim of this session is to accomplish a complete exchange of scientific ideas and related difficulties in understanding and interpreting the findings. Speakers are expected to present their results in <10 minutes and reserve the remaining time for discussions between the speaker and the audience to explore solutions and collaboration. Please label your talk as A1-Triple I.

Lithium-ion batteries have driven the portable electronics market's tremendous growth and their use in transportation and grid storage sectors is expanding at a fast rate. Further boosting the energy density of these batteries requires higher voltages and greater electrode materials capacity. This symposium is intended to provide a forum for dissemination of new advances and developments in Li-ion batteries which includes new or improved materials and understanding, electrolytes, interfaces/interphases, separators, and electrochemical testing.

The severity of an energetic battery safety mishap has the potential to make high specific energy battery chemistries an at-risk technology for high-reliability applications. As such, improvements in cell and battery safety design without compromising performance continues to be a major focus for researchers, manufacturers and users across all sectors of the energy storage marketplace. Safe passenger travel in emerging modes of electrified transportation such as commercial aviation, marine, and novel ground transport applications is enabled by safe rechargeable battery technologies. An improved understanding of rechargeable battery failure mechanisms will facilitate regulatory agency approval and public acceptance of early deployment of advanced battery energy storage systems for high reliability applications.

The goal of this symposium is to address battery safety from the perspective of materials, cell, and battery-level design improvements which reduces the severity and consequences of an energetic safety incident. Specific topics and areas to be discussed in this symposium include but are not limited to (1) use of advanced techniques in adiabatic and isothermal calorimetry for safe battery design; (2) improvements in cell design safety features; (3) materials characterization, diagnostics, and prognostics from in-situ, in-operando, and post-mortem techniques; (4) safety of next-generation rechargeable cell technologies (such as solid-state, lithium metal, sodium, potassium, magnesium, and redox-flow); (5) effect of fast charging or aging on cell safety and degradation characteristics; (6) development of novel low or non-flammable cell electrolytes; (7) analyses that improves understanding of cell failure mechanisms and hazards; and (8) other battery safety topics not covered by the above or in other symposia.

To accelerate the pace of materials discovery, development and optimization for electrochemical energy storage systems, it is necessary to apply a combined computational and experimental approach to discover the winning candidates for next generation batteries. In this symposium, we hope to gather many researchers around the world to discuss new advances in materials design and modeling of battery materials. The emphasis of the symposium will be on the new promising electrode materials and systems, their electrochemical properties and reaction mechanisms.

The organizers would like to invite contributions that provide better understanding of the mechanism of electronic and ionic transport phenomena across electrode-electrolyte interfaces and solid-state interphases in lithium-ion batteries. The underlying principles that govern these phenomena is inextricably linked to our ability to sense and monitor electrode surface processes in situ, in real time, and with adequate spatial and temporal resolution. A better understanding of the elementary processes involved in the formation of the electrolyte/electrode interface and charge transfer kinetics in relation to solvent, salt, additive and electrode material is crucial to the further optimization of Li ion batteries. This symposium will focus on both the fundamental and applied aspects of the electrolyte and interfaces for Li and Li-ion batteries.. Papers that leverage advances in experimental and theoretical modeling approaches to characterize and describe the mechanism of electrolytes or interfacial phenomena and their impact on the electrochemical performance of the materials, composite electrodes, and energy storage systems are welcome.

The symposium is focused on new materials and new processes for the application of binder materials in the electrochemical system.

Binder materials applied in fuel cells, capacitors, PEC and photovoltaics are also encouraged to submit. Physical properties contributing to multifunctionality of binders applied to electrode materials such as silicon, sulfur, etc. for batteries and solid-state electrolyte are of particular interest to the symposium. The symposium will cover new materials development, electrode and electrolyte processing and interface characterization as well as system performance. The symposium will feature oral presentation, poster, and invited talks from subject-matter experts.

The purpose of this symposium is to bring together researches investigating interactions between temperature and battery behavior at a range of length scales, time scales, and severity.

However, the complex and stochastic electrochemical phenomenon of batteries, especially in Li-ion systems, demands fundamental understanding, instrumentation, and multiphysics modeling for informed thermal management design. Further, growing interest in extreme conditions, like low temperature environments or fast charging, exacerbate self-heating behaviors, drawing attention to local and global temperature variations. The topics of this symposium includes but is not limited to:

(1) Local phenomenon driven by temperature
(2) Thermal gradients and transients
(3) Thermal management design
(4) Instrumentation of cells and packs
(5) Extreme environments
(6) Heat generation measurement/estimation

Theoretical analysis, experimental investigations, descriptions of new techniques for the study of corrosion, and analyses of corrosion products and films are of interest.

Nuclear power reactors presently generate ~10 percent of the world’s electricity. Over 400 reactors are in operation and nearly 50 more are under construction. Further, several Generation IV reactors and small modular reactors (SMR) are currently being designed to improve safety, efficiency, and optimize fuel cycle and waste management. Several countries have licensed construction of nuclear fuel waste repositories or are in the process of considering it. A critical factor in all designs, whether currently in operation or being designed, is the understanding and control of a wide range of corrosion issues. This symposium focuses on all corrosion issues involved in nuclear power related to fuel cycle (from mining to reprocessing and disposal); in-reactor corrosion; design and function of in-reactor sensors; corrosion considerations for next generation reactor systems such as molten salt reactors; and corrosion issues in short-term and long-term waste storage.

This symposium focuses on issues pertinent to advances in traditional damascene interconnects, and new materials and integration methods for 3D interconnects. An emerging technology or device architecture called 3D integration is based on the system performance gains that can be achieved by stacking and vertically interconnecting distinct device layers. The 3D concept of replacing long 2D interconnects with shorter vertical (3D) interconnects has the potential to alleviate the well-known interconnect (RC) delay problem facing the semiconductor industry today. Additional benefits of the 3D process include reduced die size and the ability to optimize distinct technologies (analog, logic, RF, etc.) on separate vertically interconnected layers. An application area where large performance gains can be obtained is high-density device/sensor arrays where processing power is placed within each individual device. Damascene copper interconnects, introduced at the 0.25 µm node, have spanned six technology nodes, and are expected to be used for the foreseeable future. Despite the history of success, there are new challenges including increases in effective resistivity, electromigration and stress migration resistance, and the integration of porous low-k dielectrics and air gaps. This symposium brings together researchers to discuss the challenges and solutions to extend damascene copper interconnects well beyond the 45 nm node. The aim of this symposium is to discuss the proposed architectures and applications of 3D integration, and the various enabling materials and processes that are required to bring the technology into full commercialization. Broadly, the enabling process technologies include wafer/die thinning, wafer/die bonding, and vertical interconnect fabrication. Each of these process technologies will leverage novel materials, and much of the emphasis of this symposium is on the materials science of these 3D integration materials. Ideally, this symposium brings together researchers to discuss the various merits of the presented 3D device architectures, materials, and fabrication methodologies.

Production of renewable energy requires large quantities of water, and supply of fresh water needs energy. Electrochemical sciences play a huge role in disrupting, to some extent, this interdependence. For example, semiconductor-assisted photocatalysis and plasma-assisted processes are highly useful in the removal of pollutants dyes and harmful microorganisms from water. Contextually, the aim of this symposium is to bring together researchers interested in studying semiconductors, materials and processes for water remediation, such as removal of pollutants, dyes and harmful microorganisms for water. Semiconductor materials useful for the removal of emerging contaminants, such as pharmaceuticals, are also encouraged for submission.

In 2016, the U.S. Department of Energy (DOE) launched the Energy Materials Network (EMN) to accelerate the process of materials discovery, development, and ultimate deployment in major clean energy sectors. Innovations in clean energy technologies are vital to domestic energy security and economic growth. Consistent with the EMN vision, moving transformational energy technologies forward requires an honest discussion of the challenges and opportunities in critical materials R&D. An integrated approach spanning materials design and synthesis through process scale-up and qualification is essential to this effort. This symposium brings together materials experts and stakeholders from multiple sectors covered in the current EMN portfolio. This includes world class leaders with multi-physics and multi-scale expertise from the EMNs as well as leaders of other high impact materials initiatives in chemical and electrochemical systems for clean energy applications. Some common material challenges across all EMNs include interfaces, corrosion, performance, benchmarking, analysis, and computational modeling. It is expected that cross-cutting conversations at this session foster synergy for future collaborations.

For electrochemical energy storage systems such as batteries, (pseudo-) capacitors and other emerging storage devices, the gas/solid, liquid/solid, and solid/solid interfaces are critical nexus where many important physical and chemical processes take place. For example, the formation of the solid-electrolyte interphase (SEI) is one kind of electrochemical deposition at the electrode surface. How the SEI is formed and what it is composed of are strongly related to battery performance and safety (e.g., dendrite formation at lithium metal anode). Electrode/electrolyte interfaces usually experience transformations during battery charge-discharge cycling, resulting in changes in cycle life and energy capacity. Similarly, the interfacial couplings and reactions between electrodes and solid electrolytes dictate the operation and performance of solid-state batteries in distinct ways. Analysis of such interfacial processes provide critical information for materials design and operational improvements for numerous energy storage systems. Examining the methodology used for diagnosis of interfacial (heterogeneous) charge transfer processes is also key to understanding the involved chemistries. This symposium seeks oral and poster presentations on advanced methodology, innovative structure design, and research frontiers on interfacial analysis for energy storage.
