How does a sodium ion battery work?

Found all over the earth, sodium can be extracted from seawater, making it virtually inexhaustible. Sodium-ion batteries operate on the same principle as lithium-ion batteries. The battery is charged and discharged as sodium ions travel between the positive and negative electrodes.

Could a sodium ion battery replace lithium?

It would be the world’s first commercialization of a sodium-ion battery—one that could quickly replace the mainstream lithium-ion battery. Professor Shinichi Komaba of the Tokyo University of Science, a leading researcher of sodium-ion batteries, noted, “We may be saying ‘farewell’ to lithium in five years.”

Can a solid sodium ion battery combust?

In November of 2021, Nippon Electric Glass (Otsu City) announced that they had developed a solid sodium-ion battery that is unlikely to combust using crystallized glass for the positive and negative electrodes. The battery’s plate-like structure has a thickness of 0.3 millimeters. The required output is achieved by stacking multiple plates.

Who invented a battery in Japan?

Japan has been at the cutting-edge of battery invention for more than a century. Komaba is the latest in a long line of TUS pioneers in battery research and development. In fact, TUS graduate and engineer Sakizo Yai invented the dry-cell battery in 1887. And, like Yai, Komaba's achievements are beginning to receive recognition.
