Raising demand for high-density, long-duration energy storage is driving the development of new beyond-lithium-ion battery chemistries, including sodium-ion batteries which offer an affordable and earth-abundant alternative. The performance and lifetime of many non-aqueous battery chemistries depend on the efficient formation of the solid electrolyte interphase (SEI). During the first charge cycles, the electrolyte is reduced at the anode surface and insoluble degradation products form a passivating layer, allowing ion transport while preventing additional electrolyte degradation. Key differences between the properties of sodium and lithium, including increased solubility of degradation products, affect the efficiency of SEI formation. As a result, sodium-ion batteries are subject to lower columbic efficiency, faster capacity fade, and higher resistance growth than lithium-ion. Soluble degradation products can also diffuse to the cathode, a form of cross-talk with additional implications on battery lifetime. Better understanding of the formation and dissolution of soluble degradation products, including methods to measure the relative concentration of dissolved electrolyte products, is necessary to overcome these limitations. Here we use electrochemistry to study the characteristics of the SEI and its implications on battery performance and design. In the first part, we examine the impact of system design on experimental results. First, we demonstrate how cross-talk of soluble products can impact the study of working electrode behavior in sodium-ion systems. We then investigate candidate reference electrodes to minimize the effects of cross-talk and voltage drift in the system. Additionally, we provide a benchmark of the compatibility between non-aqueous solvents and materials of construction for designing custom spectroscopic and electrochemical reactors. In the second part, we develop a new electrochemical approach to soluble product analysis. While differences in solubility have been studied through ex-situ spectroscopic techniques, in-situ detection of soluble degradation products can allow increased understanding of SEI dynamics and enable real-time evaluation of the efficiency of SEI formation. Here, we fabricate novel interdigitated electrode arrays( IDAs) with a high aspect ratio of Wgen¬ to Wcol (10-40:1) using photolithographic techniques. Using geometry to bias diffusion we achieve low feedback while maintaining relatively high collection efficiency (25-40%). Through this work, we demonstrate electrochemical monitoring of soluble products in several SEI formation and product detection schemes. Utilizing this technique, it is possible to observe the proportion of electroactive soluble degradation products formed as a function of potential and evaluate electrolyte formulations. Finally, we turn our attention to parallels between the SEI and solid-state electrolytes to understand the role of interfacial potential on the nature of ionic conduction and electronic insolation.

All solid-state batteries (ASSBs) show great promise toward becoming the dominant next-generation energy storage technology. Compared to conventional liquid electrolyte-based lithium ion batteries, ASSBs utilize nonflammable inorganic solid-state electrolytes (SSEs), which translate to improved safety and the ability to operate over a wider temperature range. Although the recent discoveries of highly conductive SSEs led to tremendous progress in ASSB's development, they still face barriers that limit their practical application, such as poor interfacial stability, scalability challenges and limited performance at high current densities. Additionally, efforts to develop sustainable manufacturing of lithium ion batteries are still lacking, with no prevailing strategy developed yet to handle recyclability of ASSBs. Recognizing this, this dissertation seeks to evaluate SSEs beyond conventional factors and offer a perspective on various bulk/interface and chemical/electrochemical phenomena that are of interest to both the scientific community and the industry. Beginning from an introduction to the current state-of-the-art, rational solutions to overcome some major fundamental obstacles faced by the ASSBs will be discussed, strategies toward enabling scalability as well as potential designs for sustainable ASSB recycling models will be discussed. Specifically, lithium solid-state battery systems were studied using sulfide based SSEs. The electrochemical reactivity of the argyrodite Li6PS5Cl system was studied, to gain insight into its reaction mechanisms, products, and reversible redox behavior. In terms of scalability, binder-solvent-sulfide compatibility was evaluated, in order to enable scalable roll to roll processability of thin and flexible sulfide SSEs. To overcome performance limitations at the anode, carbon free alloys electrodes were enabled, achieving high critical current densities and low temperature operation of ASSB full cells, addressing a key bottleneck in ASSB development. Finally, a fully recyclable ASSB model was designed, incorporating direct recycling approaches that reduce energy and greenhouse gas emissions compared to conventional recycling technologies. Overall, this dissertation offers a deepened understanding of interfacial phenomena, and improved design strategies that translates into better material selection for high performance and sustainable ASSBs.

"Nuclear energy and electrochemical energy storage, such as batteries, are key parts to the clean energy transition of critical infrastructure. This work aims to define, monitor, and modify interfacial layers that would improve the utility of materials in harsh environments seen in nuclear and energy storage applications. First, the studying of zirconium alloys, which is used as nuclear cladding, was done to better understand the degradation mechanisms within an extreme environment. High-resolution characterization techniques were used to correlate corrosion mechanisms to equivalent circuit models from novel in-pile electrochemical impedance spectroscopy sensors. Advancement in this sensor technology could provide further insight and monitoring of the complex degradation mechanisms in a harsh nuclear core environment. A novel method was developed to spatially map Raman spectral features throughout the oxide cross-section, revealing a direct correlation between tetragonal zirconia phase and compressive stress, thus supporting the theory of a stress-induced breakaway phenomenon. Additionally, a comparison of interface- and relaxed-tetragonal phase revealed a difference in stabilization mechanisms, where relaxed-tetragonal phase is stabilized solely from sub-stoichiometric contributions. Coupling Raman mapping with elemental analysis via energy dispersive X-ray spectroscopy and scanning Kelvin probe force microscopy led to a distinction of secondary-phase particles and their nobility relative to surrounding zirconium oxide and metal. Lastly, a p-n junction at the tetragonal/monoclinic zirconia interface was observed, supporting the theory that the tetragonal layer at the metal/oxide interface provides an additional barrier to an otherwise diffusion-limited oxidation mechanism. Other interfacial studies were conducted on next-generation battery anodes. High-capacity lithium, deemed the "Holy Grail" of battery materials, undergoes unstable interactions in most, if not all, environments. In a cell, this causes poor cycle life and/or possible safety concerns via dendritic-driven short circuiting. Novel development of lithium-metal batteries was accomplished firstly with a facile design of a closed-host, porous/dense bi-layer interfacial structure formed on lithium through a two-step ex situ/in situ process, only made possible with an electrolyte additive included in the cell. This design prevented dendrite growth, improved interfacial flexibility and ionic conduction when compared to a traditional LiF coating, reduced volume fluctuations, and prevented extensive parasitic reactions. In summary, the works presented here were done in effort to better understand and control interfacial mechanisms in both nuclear energy and energy storage fields."--Boise State University ScholarWorks.

The idea of a NATO Science Committee Institute on "Materials for Advanced Batteries" was suggested to JB and DWM by Dr. A. G. Chynoweth. His idea was to bring together experts in the field over the entire spectrum of pure research to applied research in order to familiarize everyone with potentially interesting new systems and the problems involved in their development. Dr. M. C. B. Hotz and Professor M. N. Ozdas were instrumental in helping organize this meeting as a NATO Advanced Science Institute. An organlzlng committee consisting of the three of us along with W. A. Adams, U. v Alpen, J. Casey and J. Rouxel organized the program. The program consisted of plenary talks and poster papers which are included in this volume. Nearly half the time of the conference was spent in study groups. The aim of these groups was to assess the status of several key aspects of batteries and prospects for research opportunities in each. The study groups and their chairmen were: Current status and new systems J. Broadhead High temperature systems W. A. Adams Interface problems B. C. H. Steele Electrolytes U. v Alpen Electrode materials J. Rouxel These discussions are summarized in this volume. We and all the conference participants are most grateful to Professor J. Rouxel for suggesting the Aussois conference site, and to both he and Dr. M. Armand for handling local arrangements.
