<p>CATL plans to begin fitting sodium-ion batteries in passenger cars by Q2, with the first model from GAC Aion. The company has completed winter testing for its sodium-ion batteries in light commercial vehicles and aims for mass production in July. CATL's sodium batteries excel in high-power discharge and are designed for extreme cold, retaining 90% capacity at -40°C. The company is also developing its third-generation sodium battery, targeting energy densities comparable to lithium iron phosphate batteries within three years.</p>
