Chinese engineers develop sodium ion battery: it works normally at-40 ℃, and it can still run healthily after 2000 charges and discharges.

CTOnews.com July 25 news, according to CCTV Finance reported on the evening of July 24, engineer Ouyang Chuying using simulation programs, combined with a large number of experimental data accumulation, and the periodic table of elements in the screening, combination, simulation testing, using big data technology, in 10 months developed a new type of power sodium ion battery.

The new sodium-ion battery can maintain excellent performance in cold environments. Ouyang Chuying and his assistants screened and confirmed the material system of sodium ion battery through data means. In a sealed box at-40℃, sodium ions rush to the negative electrode to complete charging through the conduction of electrolyte, and then return to the positive electrode to realize discharge. Under extreme low temperature environment, it still works normally.

The data show that the sodium-ion battery can operate healthily after 2000 times of uninterrupted charge and discharge, and the fluidity of sodium at low temperature is excellent. Ouyang Chuying introduced,"In this case, we may use it to the South Pole, or to Mount Everest or the Himalayas." "

CCTV news reports pointed out that the current winter, electric car range will be greatly reduced, turn on air conditioning heating has become a "luxury" enjoyment. The problem is that lithium-ion batteries, which are currently widely used, are very afraid of low temperatures. "It's like when your fingers are exposed for a long time in a cold environment, they become inflexible." Sodium has a rich reserve in nature. With the rapid development of clean energy today, the invention of sodium ion battery "coincides with the right time."

CTOnews.com previously reported that according to an analysis conducted by Japan's Mitsui & Co. Strategic Research Institute in the first half of the year, China is constantly improving its strength in the development competition of lithium-ion battery alternatives. In the past 10 years, patent statistics related to post-lithium-ion battery technology show that China is in the leading position, accounting for more than half of all patents.

Sodium-ion batteries may be one of the most hotly contested technologies of the post-lithium-ion era. Japanese media patent analysis also shows that China maintains a leading position in this technology over Japan and the United States, and Chinese companies are expected to start mass production of sodium-ion batteries this year.
