Lithium ion secondary batteries are an energy storage system with high energy density. They are practically used as a power source on portable devices. However, when considering large-scaled applications such as power source for electric vehicles and solar and wind power generation, further advancement not only in energy density but also power density is needed. For a power source that is capable of driving an electric car solely by electrical energy, an energy density of 700 Wh/kg is required. This level of performance, capable of replacing the internal combustion engine, does not exist on the current trajectory of battery device design. An innovation of the battery technology is required that can store power using a completely new concept.
This proposed research targets the development of a post lithium ion battery technology that designs and synthesizes ideal battery materials on the atomic and molecular levels. Researchers that represent Japan from the fields of chemistry and physics will participate in this research program as central researchers, joint researchers and core members. They will work towards interdisciplinary integration through cooperation and do basic research such as:
- Designing innovative battery materials (active materials, electrodes, electrolytes, separators, etc.) on the atomic and molecular level
- Developing new-concept storage batteries
- Developing high level analysis and characterization
- Developing material computation and simulation technologies
This basic research will develop the component technologies of post lithium ion batteries a step ahead of the world. Through the above steps it will design new-concept battery systems, synthesize revolutionary new materials and establish cutting edge simulation and measurement/analysis technologies.
