宁德时代纳电池首搭乘用车，首款车型为长安欧尚520

Core Viewpoint - CATL and Changan Automobile have jointly unveiled their first sodium-ion mass-produced passenger vehicle, set to launch mid-year, highlighting the sodium battery's low-temperature performance in harsh winter conditions [2][3]. Group 1: Product Launch and Features - The sodium-ion battery maintains over 90% capacity at -40°C and can discharge stably at -50°C, with an energy density of up to 175Wh/kg [3]. - The sodium battery's energy density is lower compared to lithium batteries, which range from 250-300Wh/kg for ternary lithium and 150-200Wh/kg for lithium iron phosphate [3]. - The sodium battery industry has faced slow development due to the lack of a complete supply chain and reliance on lithium battery production lines [3]. Group 2: Market Implications and Strategic Partnerships - The collaboration between CATL and Changan, a major player in the automotive industry, is expected to accelerate the adoption of sodium batteries in passenger vehicles [4]. - Changan's various brands, including Avita and Deep Blue, will incorporate CATL's sodium batteries, indicating a strategic push towards this new technology [4]. - The initial vehicle showcased at the launch was disguised, leading to speculation about its branding, but it was identified as an Oshan 520 [4]. Group 3: Consumer Acceptance and Cost Considerations - Consumer acceptance of sodium batteries is still uncertain, and Changan is cautious about using its main brands for initial launches [5]. - The cost of sodium batteries remains a concern, currently around 0.45 yuan/Wh, compared to lithium iron phosphate's cost of 0.340-0.410 yuan/Wh [5]. - Despite current challenges, sodium batteries have significant long-term market potential in various applications beyond vehicles, such as energy storage and starting batteries [5]. Group 4: Future Outlook and Industry Standards - CATL views sodium and lithium batteries as complementary technologies that can enhance the overall electric vehicle ecosystem [6]. - The sodium battery sector is entering a new phase with the implementation of standards for energy storage applications, marking a shift towards industrialization [6]. - By 2026, CATL plans to scale up sodium battery applications across multiple sectors, including energy storage and electric vehicles [6].
