Changan is accelerating the advancement of sodium-ion battery technology as part of its global battery strategy. Tan Benhong, Chief Brand Officer of China Changan Automobile Group, noted that Changan will continue to roll out new sodium-ion battery–equipped vehicles across multiple brands in the near future.
Newly developed sodium-ion (Na-ion) batteries could offer much faster charging speeds, higher energy density and improvements in safety compared with conventional lithium-ion (Li-ion) batteries, scientists say.
Na-ion batteries are safer than Li-ion batteries, as noted in a 2025 study by researchers at the Islamic University of Technology, Idaho State University, and University of Waterloo. This is because the stable sodium ions they contain are less prone to the chain reaction that causes Li-ion batteries to burn, or even explode, when damaged.
In the real world, the results could help Na-ion batteries become more widely adopted for uses that require incredibly fast charging or discharging rates. For example, grid-scale battery energy storage systems would benefit from the capability to rapidly discharge energy on demand.
