Will lithium batteries be replaced by sodium ion batteries?

The new energy industry is a constant topic every day, and the news that CATL will launch sodium-ion batteries has attracted attention. With the increase in application scenarios, the market demand for lithium has increased significantly, and the supply of lithium resources is limited. Therefore, it is imperative to find alternatives to lithium-ion batteries.

Under this circumstance, sodium-ion batteries have come into people’s vision because they have similar working principles as lithium-ion batteries. Sodium has the advantages of wide global distribution, rich content in the earth’s crust, and low mining costs. These characteristics make sodium-ion batteries have The basis for large-scale applications.

However, the energy density and cycle life of sodium-ion batteries are lower than that of lithium iron phosphate, but the sodium reserves are abundant, which also makes sodium-ion batteries more cost-effective compared to lithium-ion batteries.

In addition to rich sodium reserves, sodium ion batteries also have the advantages of excellent high and low temperature performance, good rate performance, and high safety. Compared with lead-acid batteries, they only have no advantages in recycling, and other indicators are excellent. Just as lead-acid batteries are still active in the market, sodium-ion batteries will naturally have a place. With the gradual improvement of the industrial chain and the improvement of production technology, the cost advantage of sodium batteries will gradually become prominent.

Will lithium batteries be replaced by sodium ion batteries?

Battery manufacturers have invested heavily in lithium battery research in the early stage, which will not affect the normal output of lithium batteries in the short term. However, as the price of lithium rises, manufacturers will have more power to mass produce batteries. Mass production of sodium batteries will be available. Will gradually replace some places where lithium batteries were originally used.

In general, the low energy density and resource advantages of sodium-ion batteries determine its future application scenarios for energy storage and lead-acid replacement. Keheng believes that sodium batteries and lithium batteries are complementary rather than competitive.

In the field of power batteries, sodium batteries do not have the advantages of lithium batteries; in the field of energy storage, distributed energy storage lithium batteries have huge advantages, and sodium batteries have certain advantages in large-scale energy storage. Therefore, sodium batteries will not pose a threat to lithium batteries, and the two can form a complementary relationship in the field of energy storage.
