Although the dominant position of the lithium-ion battery can still continue to continue long, this does not affect other types of batteries "various gods". Scientists from the University of California Santa Barbara are studying sodium ion batteries. They find that the accident of hydrogen is the original deficiencies of sodium ion battery technology in degradation and performance.

According to the calculation of sodium ion technology, if hydrogen is excluded from the entire material processing process, the performance of the sodium ion battery will be greatly increased to achieve the level of competing with lithium ion batteries. The processing of lithium-ion batteries has always been indexed, and the procurement of the material required for the battery and the potential problems of lithium itself, especially in power lithium ion batteries become more prominent. Recycling and ladder use is one of the ways to save battery costs, but in order to get rid of richer, more cost-effective batteries, researchers have been working hard to explore new batteries, seeking new opportunities.

Sketch of sodium is the research direction of many people in the battery industry. This technology is now fully commercialized, because the defects of lithium-ion batteries include degradation problems and performance losses, and the "hard injury" of sodium ion batteries is faster than lithium-ion batteries. Therefore, although the sodium ion battery has low cost, high security, environmentally friendly, how is the problem to use a known chemical substance that is known to degradation.

A new papers published in the "Material Chemistry" magazine statement, scientists calculate, a common cathode material-manganese oxide sodium oxide sodium oxide is caused by the presence of hydrogen. They also think that similar mechanisms may have adverse effects on the performance of lithium-ion batteries, but this should be more research to prove. Hydrogen is the most abundant element known in the universe, can enter the material in many stages of battery manufacturing, the effect of hydrogen on various renewable materials is a desirable research category.

Calculation declaration of UCSB, the presence of hydrogen peroxide layer reduces energy required for manganese atomic fracture and dissolution. "Because the hydrogen atom is small and active, it is a common contaminant in the material. Calculation Materials Scientists in Santa Barbara, "Now we have noted the harmful effects of hydrogen, then measures can be taken during the manufacturing and packaging of the battery to inhibit the combination of hydrogen, thereby increasing battery performance.
