- <p><b>Background and Aims:</b> The push for a decarbonized society has intensified research into energy storage and generation technologies. This paper explores the application of Multilayer Ceramic Capacitor (MLCC) technology—a core technology of TAIYO YUDEN CO., LTD—to the development of advanced energy devices. MLCCs are miniaturized, high-capacity capacitors constructed by alternately stacking thin dielectric ceramic layers of BaTiO<sub>3</sub> (barium titanate) and Ni metal layers, followed by co-firing. This study focuses on enhancing BaTiO<sub>3</sub> powder properties for producing thin dielectric layers and applying this knowledge to the development of oxide-based all-solid-state batteries (ASSBs) and metal-supported solid oxide fuel cells (MS-SOFCs). The research aims to leverage MLCC technology to achieve the miniaturization and efficiency required for these next-generation energy devices.</p><p><b>Methods and Results:</b> The study began with improving the solid-state synthesis of BaTiO<sub>3</sub>, essential for achieving the thin dielectric layers needed in MLCCs. The reaction mechanism was investigated using fine BaCO<sub>3</sub> and TiO<sub>2</sub> powders, revealing that BaTiO<sub>3</sub> formation initiates at the contact points between the two materials, followed by Ba ion diffusion into TiO<sub>2</sub>. By optimizing the particle size and homogeneity of the reaction mixture, the team successfully synthesized highly crystalline BaTiO<sub>3</sub> particles. These findings were then applied to the synthesis of battery materials, focusing on achieving a uniform dispersion of fine particles, essential for the thin-layer construction in both ASSBs and MS-SOFCs. The study demonstrated that using MLCC-based processing techniques—such as tape casting, stacking, and co-firing—enabled the production of all-solid-state batteries and SOFCs with promising performance characteristics.</p><p><b>Conclusions (Outlooks):</b> The research highlights the potential of MLCC technology to drive advancements in energy device miniaturization and efficiency. The enhanced solid-state synthesis of BaTiO<sub>3</sub> and its application to battery materials underscore the feasibility of developing compact, high-performance energy devices. Future work will focus on further refining these materials and processing techniques, potentially leading to the commercialization of MLCC-based all-solid-state batteries and SOFCs. The success of this approach could contribute significantly to the development of sustainable energy technologies, aligning with global efforts toward decarbonization.</p><p>脱炭素社会の実現に向け，当社コア技術である積層セラミックコンデンサ（MLCC）技術を活用し，エネルギーデバイスの開発を進めている。小型・大容量のMLCCは，1 μm以下の薄層誘電体セラミックス層，Ni金属層といった異種材料を交互に積層し，一体焼成により作製される。薄層シート実現のためのBaTiO<sub>3</sub>微粉末合成や，MLCC技術を活用した，酸化物系全固体電池や金属支持型固体酸化物燃料電池の，微粒子合成～薄層シート積層，一体焼成についての検討内容を紹介する。</p>
