    <jats:title>Abstract</jats:title> <jats:p>The global transition to sustainable energy systems requires breakthroughs in electrochemical storage technologies that are not only safe, but also resource-efficient. Solid-state batteries (SSBs), which use superionic solid electrolytes (SEs) instead of flammable liquid electrolytes, are at the forefront of this transformation. In general, SEs promise increased safety, access to high-voltage cathode and metal anode chemistries, and new avenues for circular design and recyclability. However, to reach their full potential, intertwined challenges related to ion transport, (electro)chemical stability, manufacturing, processing, and cost must be overcome. This “2026 Roadmap on Next-Generation Solid Electrolytes for Battery Applications” outlines new directions that will contribute to research in the field of SSBs over the next decade. It provides an overview of the current state of the art in sulfide- and halide-based solid electrolytes for Li and Na systems, examines post-Li/Na chemistries (K, Mg, and others), and highlights advances in hydroborates, fully reduced (irreducible), and compositionally complex (high-entropy) electrolytes, as well as glass-ceramic electrolytes. Beyond material innovation, the paper emphasizes the critical role of redox activity in SEs, scalable processing, high-throughput synthesis, and machine learning, as well as operando analytics and nuclear magnetic resonance spectroscopy to accelerate discoveries and gain a better understanding of structure-property relationships. Finally, the growing importance of recycling and circular design for ensuring sustainability is highlighted. By combining insights from chemistry, materials science, data (computational) science, and manufacturing, this article assumes that future SEs will progressively evolve from passive components to active design elements in high-energy-density electrochemical systems. The integration of multidisciplinary innovations will be crucial to realizing the potential of SSBs in practical technologies that power a decarbonized world.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>Traditional selectivity of gas sensors determined by the magnitude of the response value has significant limitations. The distinctive inversion sensing behavior not only defies the traditional sensing theory but also provides insight into defining selectivity. Herein, the novel definition of selectivity is established in a study with VO<jats:sub>2</jats:sub>(M1). The sensing behavior of VO<jats:sub>2</jats:sub>(M1) is investigated after its synthesis conditions optimization by machine learning. In gases of the same nature, VO<jats:sub>2</jats:sub>(M1) shows remarkably selective for NH<jats:sub>3</jats:sub> marked with unique resistance increase behavior. Such anomalous behavior is attributed to the formation of the Schottky junction between VO<jats:sub>2</jats:sub>(M1) and the electrode. The “work function‐electron affinity” relation is summarized as the selectivity coefficient, a parameter for predicting the selectivity of the sensing material effectively.</jats:p>

    <jats:title>Abstract</jats:title><jats:p>All‐solid‐state batteries have attracted much attention because of the expected high energy density and inherent safety stemming from their nonflammable property. While improving the energy density of the cathode poses a significant challenge, here we introduce a novel battery design strategy to enhance energy density by employing bifunctional cathode material, allowing the weight ratio of the active material to be increased without using an electrolyte for the cathode. By employing lithium‐containing vanadium halide Li<jats:sub>2</jats:sub>VCl<jats:sub>4,</jats:sub> serving as both active material and electrolyte, the all‐solid‐state battery cell with no electrolyte for the cathode with a capacity approaching the theoretical limit is demonstrated. In addition, we present a guideline for improving capacity retention from the perspective of interfacial stability. Notably, thermodynamic analysis revealed interfacial instability between Li<jats:sub>2</jats:sub>VCl<jats:sub>4</jats:sub> and sulfide material. A double‐layer separator, incorporating halide materials for the cathode side, was implemented to enhance the interfacial stability and mitigate the capacity degradation. Furthermore, it was found that the rate capability depends on the lithium content in synthesized Li<jats:sub>2‐x</jats:sub>VCl<jats:sub>4</jats:sub> and does not change with the state of charge significantly. This study will contribute to designing the bifunctional cathode material for an all‐solid‐state battery and describe its unique properties.</jats:p>

    本研究では二元水素化物超伝導体の探索範囲を超え、機械学習を用いて三元水素化物超伝導体を見つけ出し、より高い転移温度を実現することだった。蓄積した結晶化学の知識と自分で開発したフィジビリティアプローチを活用し、新しい超伝導体の探索を目指した。博士課程では、まず機械学習モデルの構築に成功し、その予測性能を確認した。このモデルに基づき、La-Y-H, Y-Mg-H, Mg-Sc-H, La/Y-Ce-H体系で潜在的な超伝導性を持つ水素化物の存在を理論上で予測した。La-Y-HとLa/Y-Ce-H体系は後の実験でその存在が確認され、理論予測と実験的検証の一致が示された。最終年度、Thなどのアクチノイド系金属が安定な三元水素化物を形成可能であることも探究した。特にThとLaを含む三元クラスレート水素化物の超伝導性質に焦点を当て、高圧下で安定な三元水素化物が形成可能であることを理論的に証明した。進化アルゴリズム、第一原理計算、強結合Eliashberg法を組み合わせた分析は、超伝導メカニズムへの深い理解と未来の超伝導材料の設計への新たなアプローチを提供した。特に、200 GPaでの(La,Th)H10が高い超伝導転移温度を持つ潜在的な超伝導体であることが示された。進化アルゴリズムと第一原理計算の組み合わせは、超伝導性質の探索における計算手法の有効性を示し、Eliashberg法による分析は、超伝導メカニズムの深い理解に貢献している。これにより未来の超伝導材料の設計と発見に向けた新たな道が開かれる。この研究は、超伝導材料の理論的探索と実験的検証をつなぐ橋渡しとなり、高圧下での超伝導体の開発と応用に新たな可能性を示している。計算科学と実験科学の相乗効果により、超伝導材料研究の新しい地平が切り開かれることが期待される。
