CATL, a global battery giant, is to expand the application of its “Naxtra” sodium-ion batteries, with a formal entry into the passenger vehicle sector. “Models participating in this test include Changan Oshan, with GAC and JAC passenger vehicle models expected to follow,” an informed source revealed. CATL was at the forefront, unveiling its first-generation sodium-ion battery in July of that year, which ignited widespread industry interest. He acknowledged that sodium batteries are still in their early development stages but predicted a faster development curve and slope compared to lithium batteries. Editor’s commentAlthough the current energy density of sodium-ion batteries at 175Wh/kg is lower than that of lithium iron phosphate batteries, the performance of sodium-ion batteries in low temperatures can help them gain an advantage.
