What is a sodium ion battery?

Sodium-ion batteries operate analogously to lithium-ion batteries, with both chemistries relying on the intercalation of ions between host structures. In addition, sodium based cell construction is almost identical with those of the commercially widespread lithium-ion battery types.

Are sodium ion batteries a viable alternative to lithium-ion technology?

There are also other aspects that make sodium-ion batteries a viable alternative to lithium-ion technology, such as superior environmental credentials, enhanced safety, and better raw material costs.

Are sodium-ion batteries ready for commercialization?

Sodium-ion batteries are undergoing a critical period of commercialization with Chinese cleantech juggernauts actively working on their products.

Is Chery the first automaker to use CATL's sodium-ion batteries?

Chery will be the first automaker to use CATL’s sodium-ion batteries . In 2021 CATL stated that their first generation of sodium ion cells would achieve 160Wh/kg, however, we haven’t seen a datasheet or better still an independent test.

Why are sodium ion batteries cheaper than lithium-ion?

Namely, sodium-ion’s lower cost mainly comes from abundant sodium and low extraction and purification costs. Sodium-ion batteries could potentially use aluminum for the anode current collector instead of copper – which is used in lithium-ion – additionally reducing costs and supply chain risks. Further modifications are also possible.

Are sodium ion batteries better than lithium phosphate batteries?

However, in a recent interview, CATL Chairman Robin Zeng voiced much more audacious expectations, saying that sodium-ion batteries are a better bet, potentially replacing up to 50% of the market for lithium iron phosphate batteries, which CATL presently dominates.
