Sodium-ion Battery

BYD said that the mass production timeline for its sodium-ion batteries will be determined based on market and customer demand.

CATL and Changan jointly unveiled a passenger vehicle model equipped with sodium-ion batteries, slated for market launch in mid-2026.

Changan said it will collaborate with CATL to address mobility challenges in cold winter weather.

CATL's Naxtra brand sodium-ion batteries have been loaded into a passenger vehicle model from Changan Oshan and are set to undergo winter testing.

The first passenger vehicle model equipped with CATL's sodium-ion batteries will come from GAC Aion.

The sodium-ion battery is engineered for extreme cold environments, retaining 90% of its usable capacity at -40°C, CATL said.

LG Energy Solution plans to complete construction of the pilot production line within the year and begin sample production.

In 2026, sodium batteries will be used on a large scale in battery swap, passenger vehicles, commercial vehicles, and energy storage, CATL said.

Eve Energy will invest about RMB 1 billion ($140 million) in this sodium-ion battery project, with an annual production capacity planned at 2 GWh.

CATL's fifth-generation LFP batteries have achieved new breakthroughs in energy density and cycle life, according to its chairman Robin Zeng.
