Energy Storage Division – Shigeto OKADA –
Electricity Storage Technology
- Development of a new redox couple with multi-electron reaction to improve the energy density
- Development of an aqueous Na-ion battery to suppress the material cost and environmental impact
- Development of a solid-state rechargeable battery to improve the safety, cyclability and reliability
- Investigation of the degradation and thermal runaway mechanism to improve the chemical and thermal stability
The goal of this study is to develop low-cost, high-efficiency large-size rechargeable batteries. We hope to simultaneously provide solutions to two urgent national issues; earthquake reconstruction support through providing solutions to electricity shortages caused by Fukushima nuclear power plant accident and the industry restructuring from electronics to energy industry by Japan’s world-class battery technology. Under the NEDO RISING and MEXT ESICB project, some researches of post Li-ion battery are being conducted, to realize large-scale rechargeable batteries such as aqueous Na-ion battery.
