While lithium-ion batteries keep getting cheaper, making it difficult for alternative technologies to catch up on cost and scale, Chinese battery industry heavyweights are actively developing their sodium-ion products.
On November 18, CATL announced its second-generation sodium battery. Addressing the World Young Scientists Summit, chief scientist Wu Kai said the new battery will be launched next year – four years after the release of CATL’s first sodium-ion battery in 2021. The first generation had an energy density of 160 Wh/kg, while the next one is expected to exceed 200 Wh/kg. Mass production of the new product is not expected before 2027.
In 2023, CATL said Chinese automaker Chery would be the first to use its sodium-ion batteries. Last month, it unveiled its Freevoy hybrid battery pack, which combines sodium-ion batteries and lithium-ion batteries and is specifically designed for extended-range electric vehicles and plug-in hybrids, with a range of over 400 kilometers and 4C superfast charging. The new design leverages sodium-ion’s superior low-temperature performance to enable discharge capability in extreme cold environments down to -40 degrees Celsius and charging capability down to -30 degrees Celsius.
