    Controlling the nucleation, growth, and dissolution of Li is crucial for the high cycling stability in rechargeable Li metal batteries. The overpotential for Li nucleation (ηnc) on Li alloys such as Li-Au is generally lower than that on metal current collectors (CCs) with very limited Li solubility like Cu. However, the alloying process of CC and its impact on the Li nucleation kinetics remain unclear. Herein, we experimentally investigate the Li nucleation mechanism on Li-Au alloys using scanning electron microscopy with multiple detectors to distinguish the atomic number and topography contrast. Nonequilibrium processes near the Au CC film/lithium phosphorus oxynitride (LiPON) glass electrolyte interface were observed. Local dissolution of Li occurs concurrently with the Li plating process. This phenomenon indicates that Li nucleates as a metastable phase in Li-Au alloy CC films during Li plating due to the substantially lower interfacial energy of Li with the alloy phase. This low interfacial energy also leads to a low ηnc. Moreover, the local Li redissolution process results in a nonrandom spatial distribution of Li growth sites. Consequently, the alloy layer acts as a buffer, facilitating a more uniform distribution of the reaction sites.

    All-solid-state fluoride batteries have the potential to achieve energy densities significantly higher than those of lithium-ion batteries. A common cathode material for fluoride batteries is Cu. Cu has a low polarization, but its rapid capacity degradation due to grain growth and subsequent delamination from the solid-state electrolyte are critical issues. To enhance the performance of Cu-based cathodes in all-solid-state fluoride batteries, we explore alloying of Cu with Ni to create metastable solid solution phases (CuxNi1-x with x = 0, 0.32, 0.52, 0.72, 0.89, and 1.0). Compared to Cu, Ni has a higher polarization but exhibits superior capacity retention. The Cu0.72Ni0.28 alloy demonstrates a polarization as low as Cu, but it has a significantly improved capacity retention, which is comparable to Ni. Transmission electron microscopy observations demonstrate that the thin Ni-rich region formed near the interface inhibits Cu grain growth and delamination from the LaF3 electrolyte. By incorporating an appropriate amount of Ni into Cu, Cu-Ni alloy films combine the advantages of both metals, improving the performance of fluoride batteries.

    Solid-state batteries have potential to realize a rechargeable Li-metal anode. However, several challenges persist in the charging and discharging processes of the Li-metal anode, which require a fundamental understanding of Li plating and stripping across the interface of solid-state electrolytes (SEs) to address. This review overviews studies on Li-metal anodes in solid-state batteries using in situ observation techniques with an emphasis on Li electrodeposition and dissolution using scanning electron microscopy and SEs such as lithium phosphorus oxynitride and garnet-type compounds such as Li7La3Zr2O12. The previous research is categorized into three topics: (i) Li nucleation, growth and dissolution at the anode-free interface, (ii) electrochemical reduction of SE and (iii) short-circuit phenomena in SE. The current trends of each topic are summarized.

    Redox reactions of the Li+ insertion/extraction from one to two interlayers of graphene (Gr) on area-defined single-crystalline SiC substrates are investigated using lithium phosphorus oxynitride glass (LiPON) as the solid-state electrolyte. Unlike an organic liquid electrolyte, this glassy electrolyte does not induce a reduction current and excludes the desolvation reaction of Li+. Gr electrodes with less than two Gr layers show a single reduction peak and one or two oxidation peaks below +0.21 V (vs Li+/Li), differing distinctly from those of graphite and multilayer Gr, which display multiple peaks (multiple stage transitions). However, this finding aligns with the conventional understanding that graphite stage structure transitions proceed with stepwise increases or decreases in the number of Gr layers between adjacent Li-inserted interlayers. Cyclic voltammetry measurements indicate the presence of surface capacity due to Li+ adsorption/desorption at the LiPON/Gr interface. Moreover, Li+ insertion and extraction induce different charge transfer resistances at the level of a single interlayer. These sensitive measurements are achieved using high-quality epitaxial Gr and LiPON electrolyte, which prevent the formation of a solid electrolyte interphase and the desolvation reaction of Li+. Similar measurements using bilayer Gr produced by chemical vapor deposition coupled with a Gr transfer method and an ethylene carbonate/dimethyl carbonate liquid electrolyte are not reliable. Thus, the proposed method is effective for electrochemical measurement of Gr electrodes with a controlled number of layers.

    Herein an electro-chemo-mechanical theory, which states that mechanical work to deform a Cu current collector (CC) film influences the nucleation overpotential (η<sub>nc</sub>) for Li nucleation at the Cu CC film/lithium phosphorus oxynitride (LiPON) electrolyte interface, is examined. The finite element method (FEM) simulated the mechanical pressure that the CC film exerted on the Li nuclei at the Cu/LiPON interface, and the results agreed with the trends in our previous study. In situ scanning electron microscopy (SEM) observations for cycling of Li plating/stripping showed that Li repeatedly nucleated and grew at positions where the CC film was locally fractured, and η<sub>nc</sub> decreased with repeated Li plating/stripping because the mechanical pressure to the Li nuclei was no longer applied at locations where the CC film was fractured. On the other hand, for thicker CC films that did not crack, η<sub>nc</sub> exhibited nearly consistent values in the Li plating/stripping cycles. Consequently, the experimental results in this study supported our nucleation theory for a metal/solid-state-electrolyte interfacial system.

    This paper describes about the effect of Li-H exchange amount on total lithium-ion (Li+) conductivity of Li2+xOH1-xBr (x = -0.5 to +0.4). These samples are systematically prepared at room temperature by a dry ball-milling process using LiOH, LiOH·H2O, Li2O, and LiBr as starting materials. Synchrotron X-ray diffraction analysis reveals that single-phase Li2+xOH1-xBr samples are formed within x = -0.5 to +0.35. For improving total Li+conductivity (σt), a larger x value increases both the Li carrier density and lattice constant as positive factors, while that decreases both the crystallite size and OH rotational unit possibly assisting Li+conduction as negative factors. This trade-off provides an optimized σtof 3.6 × 10-6S cm-1at the Li-excess Li2.2OH0.8Br composition, which is ca. 3 times higher than pristine Li2OHBr (1.1 × 10-6S cm-1). The hydrogen incorporation into the lattice is confirmed by neutron diffraction analysis, and the refined composition is almost consistent with the prepared composition.

    The demand for electrical power management has increased in recent years, owing partly to increasing contribution of intermittent renewable energy resources to the overall electricity generation. Electrical energy storage systems, such as batteries and capacitors, are core technologies for effective power management. Recent significant technological developments for these energy storage devices include the use of thin film components, which result in increased capacity and reliability. Specifically, thin films with high integrity and uniformity are required in the electrolytes of solid-state Li batteries (SSLBs) and the dielectrics of electrostatic capacitors (ECs), even at extremely thin length scale (< 100 nm) and on complex nanostructures. In this regard, atomic layer deposition (ALD), which can deposit uniform and dense thin films over 3-dimensional (3D) structures, has demonstrated its efficiency in increasing device performance, particularly when applied to the electrolytes and dielectrics of SSLBs and ECs. As a result, the applications of ALD techniques to SSLB electrolytes and EC dielectrics will be examined in this study, with a particular emphasis on research instances that used high aspect ratio structures with conformal ALD coating. Finally, we will discuss how recent advances in innovative ALD processes and equipment with better controllability, versatility, throughput, and economy may further contribute to the development of SSLBs and ECs, especially at scaled-up level.

    Effects of target-substrate (TS) distance during pulsed laser deposition process on the chemical structure and lithium-ion conductivity of amorphous lithium phosphate (LPO) thin films are investigated. The shorter TS distance results in lower Li concentration, longer phosphate chain, and higher ionic conductivity. The ionic conductivity of 2.7 10 7 S/cm is obtained at 25 °C in the LPO thin film with short TS distance.

    無機固体電解質（SE）を利用したデバイスの実用化研究を進める中で、解析に適した実験系の構築は重要となる。合剤電極を用いた全固体電池（SEの両側に正極と負極を接合させた蓄電池）のoperando計測を微小スケールで行う場合は、合剤電極の一部のみを測定することになる。そのため、測定外領域の影響を考慮できない。本研究では、電極活物質とSEの異種粒子を混合分散させた溶液をインクに用い、基板上に負極、SE、正極が高精度に配置された微小固体電気化学セルを描画作製する。これにより、合剤電極を用いた系でも正極の端から負極の端にいたる全領域にわたり、ラマン分光装置などを用い、一括でoperando計測できる。

    本研究課題で用いる“固体電解質（SE）”という言葉は、「Liイオン（Li+）が伝導する固体の無機化合物」を指す。本研究では、Li金属とSEから成る固固界面の「Li = Li+ + e－ の反応のエネルギー障壁の高さ」、「界面の親和性」、「SEの耐還元性」の三つの性質の相関を原子・分子スケールの視点から理解する。実験には、Li2S-P2S5系ガラス電解質、アルジロダイト型Li6PS5ClなどのSEを用い、Li金属との界面に対し、高真空下での接触角測定などを行う。最終的に、Li金属とSEの界面の特徴を記述できる指標・変数を見出し、a priori な（経験に先立つ）界面設計の指針を構築する。

    本研究では電気化学測定を通じ、Li金属と無機固体電解質（SE）の界面近傍で起こる「空孔の発生・拡散・会合」、「空隙の生成・成長・消失」過程に及ぼす静水圧の影響を調べ、解析する。非平衡状態におけるミクロな空隙の動的振る舞いが、マクロな測定値（電流・電圧）に及ぼす影響を理解するための理論を導き、金属とSEから成る固固界面の電極反応速度論を体系化する。本研究の具体的な研究目標は以下の通りである。
