Price of sodium-ion batteries for electric vehicle solar container

Who makes sodium ion batteries?

Contemporary Amperex Technology Co. Limited (CATL), a global leader in battery technology, has made significant strides in sodium-ion batteries. In 2025, CATL unveiled the Naxtra Sodium-ion Battery platform, officially bringing lithium-free energy storage solutions into mass production.

When will a sodium ion battery come out?

Heavy-duty truck batteries will enter production in June 2025, while sodium-ion batteries for passenger EVs will roll out in December 2025. This timeline positions CATL as the industry’s first to achieve Sodium-ion Battery commercialization at scale. The Naxtra portfolio introduces two key products:

Are sodium-ion batteries good for EVs?

Sodium-ion batteries are particularly attractive for entry-level EVs due to their affordability, safety, and environmental benefits. Sodium, the primary material in these batteries, is both abundant and cost-effective. Comparing costs, sodium is priced at just $0.05 per kilogram, significantly lower than lithium’s average price of $15 per kilogram.

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

Sodium-ion batteries, developed by CATL, are a sustainable alternative to lithium-ion technology. They offer lower costs, inherent safety, and suitability for EVs and renewable energy systems. With a potential cost reduction to $10/kWh, sodium-ion batteries use sodium's abundance and safety to address energy storage challenges.

What are sodium ion batteries?

Sodium-ion batteries are a type of battery that uses sodium as its main component instead of lithium. Unlike lithium, which is relatively scarce and expensive, sodium is derived from common salt, making sodium-ion batteries more sustainable and cost-effective.

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.
