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.

Are sodium ion batteries a low-cost alternative to lithium-ion?

Provided by the Springer Nature SharedIt content-sharing initiative Sodium-ion batteries have garnered notable attention as a potentially low-cost alternative to lithium-ion batteries, which have experienced supply shortages and price volatility for key minerals.

Can sodium-ion batteries compete with low-cost Li-ion batteries?

Sodium-ion batteries are considered a promising substitute for Li-ion, but the timeline and conditions for achieving cost-competitiveness remain uncertain. This study evaluates their techno-economic potential, showing that while challenging, they could compete with low-cost Li-ion batteries by the 2030s under specific conditions.

What is a CATL naxtra battery?

CATL ’s sodium-ion batteries leverage cutting-edge technology. They provide performance levels comparable to today’s lithium iron phosphate (LFP) batteries, with notable advantages in safety, cold-weather reliability, and sustainability. The Naxtra platform boasts an energy density of 175 Wh/kg, approaching the 185 Wh/kg achieved by LFP batteries.

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 a viable substitute for Li-ion?

Sodium-ion (Na-ion) batteries present a potentially viable near-term substitute for Li-ion for two primary reasons: (1) increased abundance and availability of sodium suggests lower prices and (2) drop-in compatibility with Li-ion manufacturing infrastructure suggests rapid scaling timelines.
