自然エネルギー利用拡大のための大型蓄電池開発

抄録

　The advancement of the rechargeable battery technology is an essential approach to overcome the global warming issue. Large-scale batteries, such as Na-S battery and redox-flow battery, are expected to be installed in recently developed large scale systems such as electric vehicles, renewable energy storage, and smart grids. Owing to their high-energy density, rechargeable lithium-air batteries attract great deal of attention, and expected to be used for the next generation energy storage systems. In this paper, basic concepts and technological challenges of those battery systems are reviewed and discussed.
