FY2022 2nd GXI seminar "The Future of Storage Batteries as Social Infrastructure: 10 Small Talks on Storage Batteries"

Storage batteries have been widely used, starting with automotive starters and emergency backups, and expanding to power portable devices. In recent years, their application has grown into large-scale uses such as powering electric vehicles and storing electricity from renewable energy sources. Concurrently, production volumes have surged dramatically. It is time to rethink these components as part of our social infrastructure. Lecture will explain how practical storage batteries—primarily lead-acid, nickel-metal hydride, and lithium-ion batteries—leverage their unique characteristics min and be utilized in society, based on the requirements they must meet. It will cover challenges and future potential. Additionally, it will provide an overview of redox flow batteries and sodium-sulfur batteries, developed for large-scale applications, as well as all-solid-state batteries and air batteries, which are anticipated as next-generation technologies.
