Two advantages of sodium ion battery superior to lithium ion battery!

　　Sodium ion batteries used to be used only on special occasions, and ordinary people are not able to recognize it. With the release of a new generation of sodium-ion batteries following the new era of CATL, it suddenly became a hot topic of discussion. However, many people in the battery industry are not optimistic about sodium-ion batteries, because they are inferior to lithium-ion batteries.

　　Realistically speaking, this is not fair to sodium-ion batteries. Sodium batteries cannot be useless, otherwise it is impossible for someone to study sodium batteries when lithium batteries are in full swing. Simply put, sodium batteries are better than lithium batteries in at least two aspects.

　　First of all, in terms of reserves, the reserves of lithium resources are limited. Statistics show that 70% of lithium resources are currently distributed in South America, and China's lithium-ion battery manufacturing country is almost 80% dependent on imports. With the transformation of traditional vehicles to new energy vehicles, the demand for lithium resources is increasing, and the price of lithium has soared. If lithium-ion batteries are used in cars all over the world, lithium is not enough, and new batteries must be considered. Sodium is different. As we all know, the salt that people come into contact with every day is sodium chloride, and sodium resource reserves are very rich. The rich sources of raw materials will bring cost reductions.

　　Secondly, we know that current lithium batteries are not perfect. The risk of fire and explosion of lithium batteries is very high, as can be seen from the large number of reports of lithium battery fires in the past ten years and the strict control of lithium batteries by aviation and subway departments. In terms of use properties, although sodium ion energy density is not good, its chemical properties are relatively stable, so it is not sensitive to temperature, and it is not easy to form hard dendrites like lithium dendrites. It has the same low temperature resistance and safety. The category of lithium-ion batteries also has obvious advantages. In addition, the sodium ion battery can be safely discharged to 0V for storage and transportation without affecting its battery capacity, which greatly improves the safety of the sodium battery.

　　Therefore, in the context of intensified international competition, global energy transition, carbon emission reduction and carbon neutrality, the development of a new product route such as sodium batteries has very rich political and economic benefits. Therefore, battery manufacturers set out to develop sodium-ion batteries to meet the needs of the times.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate battery is a perfect replacement for lead-acid batteries, and it is the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.
