.I disagree. Lithium will dominate in vehicle use for a while yet. It's the lightest metal on the periodic table and much denser. And the cycles in sodium just don't compare.

● Cost of scaleTheoretically, sodium-ion batteries can reduce costs, which refers to the maturity and scale of the industry. For now, the cost of sodium-ion batteries is still higher than that of lithium-ion batteries.
● Technical supportSodium-ion batteries have some excellent characteristics, such as over-discharge to 0V and better thermal safety. This means that the requirements for current battery management technologies can be reduced, thereby reducing the disadvantage in energy density.
● Industrial chainFrom minerals to power batteries, this is a long industrial chain. In the upstream of battery companies, top 10 lithium battery companies in the world have also emerged, which jointly form an industrial chain and make the entire process run efficiently. Sodium-ion batteries have wrong demand for minerals and different requirements for processes, and it also takes time to form a new industrial chain in order to operate efficiently and truly achieve the goal of reducing costs.

How Long will it Take for the Industrialization of Sodium Batteries?

For energy storage applications, the importance of improving cycle life cannot be ignored. According to the published information, the cycle life of existing sodium-ion batteries can reach 5,000 times, but it is still much lower than the current cycle life of commercial lithium iron phosphate batteries of 8,000-10,000 times. If sodium-ion batteries want to become the backbone of the energy storage field, they still need to continue to experience in terms of technical performance.

INDUSTRIAL CHAIN:

According to the information disclosed by various enterprises, the production of sodium-ion batteries can basically follow the lithium battery production equipment that has been mature and applied. There are no major differences in the key processes in each link, and the deployment of production capacity can be quickly realized. However, in terms of key raw materials such as positive electrode, negative electrode, diaphragm, electrolyte, and collector, because brand new sodium-based materials are involved, it is necessary to develop new materials and build a brand new industrial chain system.

MASS PRODUCTION AND COST REDUCTION:

Building production lines, increasing production capacity, and achieving stable mass production are the 9981 difficulties that any technology industrialization must experience, and the experience of sodium-ion batteries has just begun. Low raw material prices are the core advantage of sodium-ion batteries to reduce costs. Before the industrial chain and production system were sound, the cost of sodium batteries did not have an advantage over lithium batteries.

It's nice to come up with new technology, but it takes time to set up an industry. Remember, lithium batteries have been around since the 90's. It's now 2024. It ain't going nowhere yet mate.
