Unique Lithium-air battery – Safely and stably operates at high energy density

A unique lithium-air battery has been developed. Its safe and stable operation was confirmed. Large capacity (10000 mAh/g), reversible charge/discharge operations were performed in atmosphere. Such operations had been impossible.

The lithium-air (Li-air) battery developed this is uniquely featured by:
1) Electrolytic solution = ionic liquid, and air electrode = carbon nanotube gel.
2) Gel air electrode has a three-dimensional structure including electron conduction, ion conduction and air-diffusion paths.


The Li-air battery, if realized, would be capable of driving the automobile in long-distance. It has a potential to substitute itself for the hydrogen fuel cell. >> More
