New Energy and Industrial Technology Development Organization (NEDO) launched a project to commercialize a new storage battery with a performance higher than that of lithium-ion (Li-ion) batteries.

The project is aimed at realizing an energy density of 500Wh/kg and a cost of ¥10,000 (approx US$91)/kWh by 2030. The project period is from fiscal 2016 to 2020, and the project budget is expected to be about ¥15 billion to 18 billion. It is participated in by 16 universities, 10 companies and four research institutes including Kyoto University, Sony Corp and Toyota Motor Corp.

In a project that lasted from fiscal 2009 to 2015, NEDO selected (1) air-zinc battery, (2) sulfide-based battery and (3) nano-interface controlled battery as batteries that have a potential to realize an energy density of 500Wh/kg. This time, NEDO plans to develop materials such as positive and negative electrodes and electrolyte, cell design technologies and other technologies to commercialize the new battery.
