S&T出版 Company Overview

Sodium-ion batteries are not only on the verge of large-scale commercialization for stationary storage applications but are also approaching mass production for automotive use in China due to advancements in high energy density. This seminar will introduce the latest trends in practical applications, as well as the progress in material technology that achieves high energy density while maintaining advantages in resources, costs, and low-temperature characteristics, along with future directions for material development.

The practical application and high performance of CPO are also expected to involve the use of polymer materials. In this seminar, we will introduce the research and development trends of the components, materials, and implementation structures of CPO, as well as the required characteristics for polymer materials and the prospects for the development of components and devices using polymers.

With the increasing capacity and high power density of AI data centers, significant transformations are required in power supply and distribution systems. In particular, there is a shift from traditional low-voltage DC power supply to high-voltage 800 V DC distribution, and technologies that efficiently supply power from medium-voltage AC to DC are gaining attention. On the other hand, the large capacity of data centers, rapid load fluctuations, and simultaneous dropouts during system faults present new challenges to the frequency and voltage stability of AC systems. SST (Solid State Transformer) is expected to be a key technology that connects next-generation data centers and power systems, as it can integrate voltage conversion and AC/DC conversion using high-frequency insulation, along with power and voltage control through GFL and GFM control. In light of this background, this seminar will explain the role of SST, circuit configurations, and the latest trends and challenges in practical implementation from the basics.
