Material creation for the development of novel energy devices
The Kanno-Suzuki Laboratory aims to contribute to the realization of a sustainable society by exploring and analyzing new materials in which ions and electrons diffuse at high speeds and developing novel energy devices. High-performance energy storage devices are essential for efficient use of renewable energy. In addition, materials with various functions are required for these energy storage devices.
On the other hand, new materials creation is not so easy. We are developing efficient methods to find materials by using computational chemistry and machine learning methods in addition to classical solid state chemistry methods. Once materials are actually found, we proceed with a series of studies that include crystal structure analysis using X-rays and neutrons, electrochemical characterization, and evaluation of output and cycle performance by making devices. Analyzing these correlations, design guidelines for new materials can be obtained. Based on the design guidelines, we will challenge the development of next-generation high-performance devices through repeated exploration and analysis and the creation of new materials.
