Half a century has passed since the Apollo 11 mission. This mission, and the “successful failure” of the 13th mission, have stimulated not only space science and engineering, but also dramatically driven the development of contemporary ground energy conversion and storage technologies. Specifically, NASA’s Artemis program aims to establish sustainable exploration on the lunar surface. The Lunar Gateway, a space station to be placed in lunar orbit, will be constructed as a solar-powered communication hub providing powerful instrumentation for planetary science, astrophysics, Earth observation, space biology, human health performance, and even a geological science laboratory combined with rover surface exploration. Through Artemis, the first woman and first person of color may land on the Moon by 2026. Lessons learned from the Artemis mission will support long-range missions, including surface sample returns from the Mars 1 Phobos satellite, and even the next giant leap, sending astronauts to Mars. Given the long-term needs of such interdisciplinary space exploration missions, a new generation of scientists and engineers must be trained and cultivated so that their ideas and innovations can support the peaceful common interest and welfare of all humankind.

Several symposia have taken place including the “Electrochemistry in Space” symposium at the 236th ECS Meeting (Atlanta, 2019) and the 2020 American Chemical Society Earth and Space Chemistry Journal In Situ Resource Utilization (ISRU) Call for Papers for the special issue, “Materials of the Universe: The Final Chemical Frontier.” However, their scope, led primarily by NASA, focused on space exploration technologies. It is our position that The Electrochemical Society (ECS) should develop an interdisciplinary education and research program in collaboration with the Minerals, Metals & Materials Society (TMS) Light Metals and Materials Processing Divisions. This research program should be geared towards training graduate students for future space engineering challenges, including those associated with the utilization of in-space resources.

The invention of the STM and AFM in the 1980s revolutionized surface science and opened up new avenues of exploration and innovation in nanotechnology. The ability of these tools to reveal local, atomic insights into surface structure and reactivity is unparalleled; however, the full potential and possible applications of electrochemical scanning probe microscopy (ECSPM) techniques, like STM, AFM, SECM, SICM, SECCM, TERS, and others, have yet to be fully explored. One reason for this is the complexity of combining electrochemistry with SPM, which typically results in setups that are even more difficult to handle and operate than standard SPMs. Furthermore, the underdeveloped knowledge and ability to control the state and evolution of the probe tip remains an additional significant barrier to progress in both experiment and image simulation. Likewise, routine operation with high spatial-temporal resolution, as well as effective analysis of large data flows, remains a challenging enterprise. Nevertheless, the richness of quantifiable signals from the electrochemical environment that can be used as feedback or detection signals in SPM continue to offer intriguing possibilities. The development of hybrid methods that couple local SPM measurements with other spectroscopic tools, like TERS and XAS, have also advanced substantially in recent years and look to grow in importance.

This interdisciplinary symposium aims to capture the state-of-the-art science produced by existing electrochemical SPM tools, while also discussing, exploring, and imagining new possible ways to gather electrochemical and structure information using improved instrumental resolution at the mesoscale and in particular, atomic scale dimensions. Contributions that provide atomic insights into the surface structure, interface dynamics, electrochemical double layer, reaction mechanisms, and associated electrochemical reactivity are most welcome. This includes applications ranging from nucleation and growth phenomena such as electroplating, etching and dissolution, oxidation, intercalation, conversion battery reactions, to site specific electrocatalytic reactions such as HER, OER, CO2RR, and more generally, SPM studies of the structure, formation and operation of functionalized surfaces that mediated electron and ion transfer reactions writ large. At the same time, emergent nanotechnological applications exploring the use of ECSPM methods for both mesoscale and atomically resolved surface modification and material synthesis are also of growing interest and importance.

The symposium includes a series of invited lectures that provide an overview of the insights achieved using state-of-the-art SPM technology and provide an outlook on promising and exciting future research directions. In addition to new experimental discoveries in physical chemistry, the symposium discusses the latest theoretical science developments and application of modern computational methods that enlighten the understanding and quantification of atomic details, and guide additionally future experimental work. Accordingly, we encourage contributions from researchers across the broad electrochemical and surface science community who work with ECSPM methods or theory to reveal atomistic and molecular insight into important and emergent issues in electrochemical science and technology.

Solid-electrolyte interphase (SEI) is essential for the existence and successful operation of lithium- and sodium-battery systems, as primary and secondary power sources since it determines its safety, power capability, morphology of alkaline metallic ion deposits, shelf-life, and cycle life. The SEI model, proposed by Peled in 1979, is still valid for all alkaline metals but continuously developed for well-adapted to each battery system in non-aqueous-battery electrolyte. Over many decades, the research has deeply explored the mechanism of SEI formation, structural properties, and composition in different batteries systems along with the design of advanced electrolytes to address the performance degradation and short cycle life related to the instability of interphases. Recent research has revealed that the solvation structure of the electrolyte might have a significant impact on SEI features. This viewpoint serves as an additional perspective that supplements, rather than substitutes, conventional SEI theory.

This symposium aims to be a platform for battery scientists and researchers to discuss recent findings in exploring interfacial reactions and spark new ideas of electrolyte or interphase modification. The topics include, but are not limited to the development of advanced electrolytes and additives, interfaces/interphases engineering, and their modifications, advanced characterizations, and mechanistic studies.

Lithium-ion batteries have significantly fueled the remarkable growth of the portable electronics market. Their application in the transportation and grid storage sectors is rapidly expanding. To further enhance the energy density of these batteries, higher cell voltage and increased specific capacity are necessary. This symposium creates a platform for sharing progress in lithium-ion and solid state batteries with the needs of future applications in mind. This includes innovations in materials, enhanced understanding of electrolytes, interfaces/interphases/separators, and electrochemical testing.

Battery technology stands as a highly successful energy storage solution, playing a pivotal role in the global energy landscape. Various battery chemistries have been crafted to suit specific applications, each offering distinct advantages and challenges that demand meticulous consideration for an optimal balance in terms of performance, safety, cost-effectiveness, and sustainability. Regardless of the specific battery chemistry, these energy storage devices are often operated at non-equilibrium conditions. Their performance is dependent on key kinetic processes such as mass conduction, charge transfer, interfacial nucleation and deposition, phase evolution, and morphological disintegration. Moreover, batteries are hierarchical systems with a high degree of chemical heterogeneities across a wide range of length and time scales. Therefore, battery research often necessitates the use of advanced in situ experimentation tools in different modalities for capturing the reaction dynamics involving metastable intermediate states.

Additionally, from the battery manufacturing standpoint, advanced characterization plays a pivotal role in controlling and optimizing the processes. The challenges associated with battery manufacturing are multifaceted, encompassing not only the intricacies of material design but also the scalability, reproducibility, and cost-effectiveness of the manufacturing processes. The battery manufacturing pipeline includes many precision processes, necessitating the development of efficient and broadly deployable methods to identify and address pain points in the manufacturing of battery materials and components.

The goal of this symposium is to establish a platform for experts across diverse disciplines to come together and share the latest advancements in in situ experimentation and in-line metrology within the realm of battery science and manufacturing. By doing so, the symposium contributes to the identification of outstanding research needs and grand challenges, particularly in connecting the intricate chemical reactions occurring at a small scale and manufacturing quality/imperfections to the overall system performance. The incorporation of innovative computational methods, such as machine learning and artificial intelligence, is strongly encouraged and welcomed.

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.

This symposium discusses 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.

This half-day symposium is comprised of 40-minute invited talks that highlight the most recent advances and trends in the area of thin film growth and electrochemical materials fabrication.

The symposium covers recent advances in fundamental aspects, methods, and applications of electrochemical and electroless growth of epitaxial and polycrystalline thin films, alloys, multilayers, and nanostructures. The symposium brings together researchers from a broad range of areas of electrochemical and engineering science to discuss the current understanding of a link between the fundamental processes and properties of electrodeposited materials and applications.

This symposium also invites contributions discussing the effects of external stimuli on the thermodynamics and kinetics of electrochemical reactions. Typical examples would be light-induced plating semiconductor electrodes or enhanced mass transport caused by magnetic fields or ultrasound. The symposium contributes to our fundamental understanding of such effects in order to use the external stimuli to tailor electrochemical reactions. Typical applications can be metal depositions or reactions related to electrochemical conversion and storage of energy. This symposium provides a space for fruitful discussions, including aspects related to both fundamental research as well as technological innovations.

Electrochemical routes for deposition of functional materials have several known advantages in terms of control, selectivity, conformality, adherence to substrate, interfacial design, mild conditions, and tunable synthetic knobs. Electrochemical deposition usually deals with “direct” electrodeposition; i.e., the electron transfer at the electrode directly results in the deposition of species on this electrode. However, indirect or electrochemical induced deposition refers to the deposition of solid species on a surface, as the result of chemical reactions in the near surface region between a precursor present in the bulk solution and an electrochemically generated precursor, mediator, or catalyst near that surface. The chemical entity that undergoes electrochemical alteration to facilitate specific reactions near the working electrode surface has been termed “pro-based.”

The field of electrochemical-induced deposition has gained quite some interest over the last decade with many new material systems and processes, and newly suggested pro-bases and methodologies to tackle also coating properties such as morphology and composites. Together with the breadth of possibilities and applications, the science behind the process has also picked up speed, however, many open questions remain. The moving boundary problem of supersaturation into the solution phase for confined interfacial deposition is more complex than for direct electrodeposition and requires modeling and simulation. The fabrication of closed coatings by electrochemically induced deposition is not evident following the inherent flocculation nature of a precipitation reaction. Nucleation and growth studies which are commonplace in direct electrodeposition are of interest also for this indirect deposition mechanism.

This symposium invites all papers on the topic of electrochemical induced deposition, including deposition of oxides, hydroxides, phosphates, and other inorganic compounds, organic materials such as MOFs and COFs, biological materials; specifically, also papers in the field of electrochemically induced deposition of gels and templated sol-gel synthesis for the fabrication of mesoporous oxides and nanostructured materials, and compounds. The symposium also invites papers with specific applications for these materials and advances in manufacturing methods.

Electrodeposition is a facile method for fabricating materials, and thus finds many applications. From energy storage to semiconductors, and from batteries to corrosion protection, the applications of electrodeposition are boundless. But these applications continually require innovations in the array of materials that electrodeposition can effectively fabricate. In this context, electrodeposition faces numerous hurdles that must be overcome. Controlling materials properties (composition, texture, crystallinity, thickness and thickness distribution, adhesion, surface morphology, etc.) and processing attributes (bath stability, parasitic reactions, etc.) is challenging especially when developing electrodeposition processes for new and emerging applications. This symposium invites contributions detailing efforts to conquer such issues through a variety of approaches including, but not limited to:

1. Electrolyte design for compositional control in deposition;
2. Epitaxial approaches including e-ALD and e-ALE for morphological control;
3. Novel cell designs for controlling current distributions in electrodeposition;

Atomic layer deposition (ALD) enables the deposition of ultra-thin, highly conformal coatings over complex, 3D topographies to tailor thin-film material properties like composition, stoichiometry, refractive index, conductivity, mechanics, porosity, and chemical functionality on the nanoscale. Consequently, ALD has become the technology of choice for a large variety of applications ranging from nanoelectronics to sustainable energy, and from catalysis to membrane ultrafiltration. Over the last 20 years, this symposium has earned a leading position among the meetings where not only ALD is discussed, but also the closely related topics of atomic layer etching, atomic layer cleaning, area-selective deposition, and molecular layer deposition (MLD)—the group commonly referred to as atomic layer processing (ALP). Other techniques derived from ALD are sequential infiltration synthesis (SIS), also named vapor phase infiltration (VPI).

Redox flow batteries have been recognized as an important perspective technology for stationary energy storage, including grid-scale energy storage, thanks to their high power performance, flexible design, and ease of scaling up. The present state of the art is mostly represented by all-vanadium redox flow batteries, even though many inorganic and organic electroactive systems have recently been proposed as alternatives. In all-liquid systems, the active species are dissolved in solvents; but the hybrid systems, in which the active species exist in distinct phases (e.g., liquid, solid or gas), can operate in three subcategories: solid/liquid, semi-solid, and liquid/gas. Mechanisms of operation and approaches to the optimization of their performance obviously differ. There is a need to develop or identify robust organic, inorganic or hybrid compounds that could function as reversible redox species in a rechargeable battery under flow conditions. Special attention shall be paid to synthesis, modification, characterization, and deep understanding of the operation of novel redox active compounds of potential utility to redox flow rechargeable batteries.

The symposium includes invited presentations, reviews, tutorial papers, and contributed papers. Papers are solicited on the fundamental and applied aspects of redox flow batteries for energy storage.

For electrochemical systems such as batteries, (pseudo-) capacitors, fuel cells, and other emerging storage and conversion devices, the gas/solid, liquid/solid, and solid/solid interfaces are critical nexuses where many important physical and chemical processes take place.

Lanthanides are uniquely useful in advanced technologies and materials. Physiochemically similar in many ways, differences in the population of 4f 6s electrons establish unique magnetic, photochemical, and catalytic properties. Lanthanides are critical materials [1]. Actinides are radioactive elements important in nuclear energy and medicine. Lanthanides and actinides have a range of oxidation states and bind ligands. Both are subject to voltammetric inspection, where electrochemistry can induce changes in electron population and oxidation state and S properties. Electrochemistry can affect separations of lanthanides from lanthanides, and lanthanides from actinides. Separations of lanthanides from lanthanides are challenging but important to further development and refinement of advanced technologies and materials. Efficient separation of lanthanides from actinides mitigates hazards in long term storage of spent nuclear fuel and facilitates nuclear medicine.

Papers addressing any aspect of electrochemistry and voltammetry of lanthanides and actinides are sought. This includes materials, technologies, separations, and corrosion. Work in unusual media and under unusual conditions, as well as characterization methods, are of interest.
