The world is currently undergoing a period of rapid economic transformation. As global awareness of environmental issues continues to grow, emerging industries such as solar energy and electric vehicles have attracted widespread international attention. In this context, capacitors—including electric double-layer capacitors, lithium-ion capacitors, and electrochemical capacitors—are widely recognized as promising high-performance energy storage devices. Beyond energy storage, capacitor technologies demonstrate significant potential and application value across a broad range of fields, including energy systems, environmental technologies, sustainable development, and biomedical applications.

　　The development and application of capacitor-related technologies align closely with Taiwan’s national industrial strategies, particularly the “Six Core Strategic Industries” initiative and the “5+2 Industrial Innovation Plan.” Capacitors are now applied extensively in electric vehicles as hybrid power systems that compensate for the limited power output of batteries, as high-power energy sources for consumer electronics and medical devices, as backup energy storage systems, and as key components in wearable electronic devices.

　　To foster interaction among domestic industries, academic researchers, and professionals engaged in capacitor research and development, and to provide a platform for the exchange of research result and professional networking, the International Conference on Advanced Capacitors (ICAC 2025) served as a major opportunity to showcase the latest advances in capacitor technology and research, while supporting the global integration of this rapidly evolving field.

　　The International Conference on Advanced Capacitors is held every three years and brings together scholars, industry experts, and students from around the world to discuss the current status and technological breakthroughs in capacitor research. The conference aims to facilitate academic and industrial exchange, identify opportunities for collaboration, and explore future research directions. The previous seven editions of the conference were organized by the Capacitor Technology Committee of the Electrochemical Society of Japan and held exclusively in Japan. ICAC 2025 marked the first time the conference was held outside Japan, jointly organized by the Electrochemical Society of Taiwan and the Capacitor Technology Committee of the Electrochemical Society of Japan.

　　The four-day ICAC 2025 program featured a single-track forum agenda and included a total of 46 oral presentations, comprising 5 Plenary Lectures, 5 Keynote Lectures, 22 Invited Talks, and 14 Contributed Oral Presentations. In addition, 46 poster papers were presented, bringing the total number of papers presented at the conference to 92. The conference attracted over 120 participants from 14 countries, reflecting its strong international engagement and impact.

　　Oral presentations were delivered by leading domestic and international scholars in the capacitor research community, while poster sessions primarily showcased research result from students at universities worldwide. To encourage academic excellence among young researchers, a Poster Presentation Competition was held, with awards presented during the closing ceremony.

　　By bringing together globally recognized experts from countries including the United States, France, and Japan, ICAC 2025 significantly enhanced Taiwan’s academic standing and international visibility in the field of capacitor research. In terms of cutting-edge technological developments, conference presentations highlighted major advances in in situ characterization techniques and microstructural observation, providing critical tools for investigating interfacial mechanisms. Research result also covered the development of three-dimensional structured materials, emerging nanomaterials, and framework materials, offering concrete directions for the future advancement of next-generation capacitor technologies.

　　Talent cultivation and international collaboration were among the key outcomes of the conference. Dedicated presentation sessions for early-career researchers helped identify promising emerging scholars, while extensive networking with researchers from Europe, the Americas, Asia, and Southeast Asia laid a strong foundation for broad international academic–industrial collaborations.

　　The organizers would like to express sincere appreciation to the National Science and Technology Council (NSTC) for its financial support, as well as to Ming Chi University of Technology for providing excellent facilities and logistical support. Their contributions were instrumental in ensuring the successful completion of ICAC 2025.

　　Overall, ICAC 2025 holds significant and lasting importance for the advancement of capacitor science and technology in Taiwan, as well as for the continued growth of academic research and international cooperation in this critical field.
