“…In the former, this high rate performance is attained by the previously described reduction in interfacial resistance by the addition of a dielectric to the electrode| electrolyte interface. The capacities of these batteries are limited by the thickness and specific capacity of the cathode materials (Julien et al, 2019), so it remains to be seen if thin film LiPON-based ASSBs can make use of the next generation cathodes being developed in parallel. Over the course of the next decade, improvements to the specific capacities of these thin-film ASSBs enabled by next-generation technology will play a pivotal role in enabling the forthcoming "internet of things.…”

Emerging Role of Non-crystalline Electrolytes in Solid-State Battery Research

As the need for new modalities of energy storage becomes increasingly important, allsolid-state secondary ion batteries seem poised to address a portion of tomorrow's energy needs. The success of such batteries is contingent on the solid-state electrolyte (SSE) meeting a set of material demands, including high bulk and interfacial ionic conductivity, processability with electrodes, electrode interfacial stability, thermal stability, etc. The demanding criteria for an ideal SSE has translated into decades of research devoted to discovering new electrolytes and modifying their structure/processing to improve their properties. While much research has focused on the electrolyte properties of polycrystalline ceramics, non-crystalline materials (glasses, amorphous solids, and partially crystallized materials) have demonstrated unique advantages in processability, stability, tunability, etc. These non-crystalline electrolytes are also fundamentally interesting for their potential contributions toward understanding ionic conduction in the solid state. In this review, we first review a decade of advances in two distinct families of non-crystalline lithium-ion electrolytes: lithium thiophosphate and lithium phosphate oxynitride. In doing so, we demonstrate two pathways for non-crystalline electrolytes to address the barriers toward development of all-solidstate batteries, viz., interfacial stability and conduction. Finally, we conclude with some discussion of the development of fundamental models of ionic conduction in the non-crystalline state, including the ongoing debate between strong and weak electrolyte theories. Collectively, these discussions make a promising case for the role of non-crystalline electrolytes in the next generation of energy storage technology.

Emerging applications for robust small format or distributed devices feature a need for power and rechargeable lithium-ion batteries could play a significant role. This review focuses on a high precision technique to controllably grow thin-film electrodes or full all-solid-state batteries, that is, pulsed laser deposition (PLD). The technique and solidstate batteries are introduced followed by a detailed showcase of the depth of PLD-based growth undertaken on cathodes, electrolytes, anodes and whole microbatteries. Emphasis is placed on the various characterization techniques available to study PLD grown components and devices, and how interfaces become both critical and arguably easier to probe in PLD grown films or devices. This work provides a perspective on the techniques, its opportunities for electrodes and devices, and how to probe the resulting growth and its evolution in batteries.

Physical Vapor Deposition in Solid‐State Battery Development: From Materials to Devices

This review discusses the contribution of physical vapor deposition (PVD) processes to the development of electrochemical energy storage systems with emphasis on solid‐state batteries. A brief overview of different PVD technologies and details highlighting the utility of PVD for the fabrication and characterization of individual battery materials are provided. In this context, the key methods that have been developed for the fabrication of solid electrolytes and active electrode materials with well‐defined properties are described, and demonstrations of how these techniques facilitate the in‐depth understanding of fundamental material properties and interfacial phenomena as well as the development of new materials are provided. Beyond the discussion of single components and interfaces, the progress on the device scale is also presented. State‐of‐the‐art solid‐state batteries, both academic and commercial types, are assessed in view of energy and power density as well as long‐term stability. Finally, recent efforts to improve the power and energy density through the development of 3D‐structured cells and the investigation of bulk cells are discussed.
