钠电池商业化进程提速多元场景落地激活产业链

Core Viewpoint - Changan Automobile and CATL have launched the world's first mass-produced sodium battery passenger vehicle, marking the beginning of large-scale application of sodium batteries in the passenger car sector [1][2]. Industry Development - Sodium batteries have entered a new stage of maturity and technological iteration after five years of industrial exploration, with costs stabilizing and a significant acceleration in industry layout [1]. - CATL's sodium battery has achieved a maximum energy density of 175Wh/kg and over 90% capacity retention at -40°C, with future electric range potentially reaching 500-600 km [2]. - The sodium battery's advantages include abundant resources, wide distribution, and reduced reliance on scarce minerals like lithium and cobalt, enhancing supply chain security [2]. Market Dynamics - The sodium battery is currently in the initial stage of commercialization, with lower cost and energy density compared to lithium batteries [3]. - It is expected that within 2-3 years, sodium battery energy density will reach levels comparable to lithium iron phosphate batteries, with significant cost advantages emerging when lithium prices exceed 120,000 yuan/ton [3]. - By the second half of 2026, sodium batteries are projected to achieve comprehensive competitiveness in terms of cost, even if lithium prices remain stable [3]. Technological Coexistence - The sodium battery industry is still in its early development phase, but its direction is clear, with expectations for it to play a significant role in energy transformation [4]. - The sodium battery is anticipated to enter a year of large-scale application in 2026, with promising prospects for industry scale expansion [4]. Industry Collaboration - Companies across the sodium battery supply chain are actively pursuing technological research, capacity construction, and strategic partnerships to accelerate their presence in this field [4][5]. - Notable developments include the establishment of a production base for sodium battery materials and ongoing collaborations with major players like CATL [5]. - Companies like Electric Science Blue Sky and Puli Te are advancing their sodium battery initiatives, with plans for mass production and increased output expected in the coming years [5].
