On the horizon, some Viking's revolutionary battery technologies are constantly dim, but for some reasons, they are never realized in reality. Sodium-ion battery is an exception to this rule and they have changed the approach to equipment production. Information port Howtogek.com speakSuch a battery is different from lithium-ion and what their advantages are.

Lithium battery nurtures the world. Their specific power makes the existence of smartphones and laptops possible, not to mention most electric vehicles. However, they also have a long list of disadvantages: high resource production costs, fragile supply chains, environmental pollution, ethical and political issues.
Every year, it is clear that if humanity will completely switch to renewable energy sources, this energy will have to be stored somewhere. And the technology of Lithium batteries cannot be reduced to the necessary level. Everyone needs a battery to be created on the basis of some rich, spacious resources that will be safer and more stable.
Here on stage and sodium-ion battery appear. Their basic principles are not different from lithium-ion: the only difference is another material used to transport ions between poles. Sodium can be found in almost anywhere, it is cheap and easy to prey. Other components, such as iron and manganese, are not difficult to get, which is a good component for sodium-ion cathode. At least, they are much cheaper than rare nickel and cobalt, used in lithium-ion batteries.
Sodium-ion battery is also safer, making them an attractive replacement for electric car batteries. Not to mention the fact that they work better at low temperatures: Due to the concentration of lithium-ion batteries, residents of some planets of the planet are simply unable to use electric cars.
But if the sodium-ion battery is very good, why are they still not popular? As you can guess, they also have their own problems, and until recently, they do not allow such batteries to become really popular.
The first Kua is a low specific power compared to the lithium-ion battery. There is no meaning for electric car manufacturers to use twice the battery resources to finally get the same power as before. But gradually the situation is changing. For example, Chinese company Catl, the largest battery manufacturer, recently launched the second generation of the sodium-ion platform and it can be compared to the power of the traditional battery, placed in passenger cars.
Moreover, not only China works in this direction. Manufacturers from the United States and Japan have also begun to be more active than sodium-ion technology, although it is undeniable that they have to go a long way before they replace electronic machines and consumer machines.
In fact, sodium-ion battery should not completely replace lithium-ion. Better technology to use where it will bring maximum benefits to minimum disadvantages. For example, to store energy in large electric networks, for light electric cars, mobile batteries and other devices designed for multiple charging cycles.
