经济观察报记者 郑晨烨 1月22日，宁德时代（300750.SZ）发布新的天行轻商系列动力电池。该系列电池涵盖超充版、长续航版、高温超充版及低温版。其中，低温版是行业首款量 产的钠离子电池，适配中小VAN（厢式车）及小微卡等车型。 按照宁德时代发布的参数数据，这款钠电池单体能量密度达到175Wh/kg，在零下30摄氏度的极寒环境中可以实现即插即充。 此前的1月17日，在四川眉山甘眉工业园区，江苏众钠能源科技有限公司（下称"众钠能源"）全球首个万吨级硫酸铁钠正极材料基地正式投产。众钠能源董 事长夏刚告诉经济观察报，随着眉山基地的投产，硫酸铁钠正极材料进入万吨级规模量产阶段，硫酸铁钠钠电芯的成本已降至约0.45元/Wh。 "巨头新品发布+核心材料量产"，这意味着行业已跨过概念验证阶段，进入规模化交付阶段，钠电商业化开始加速。 产业节奏形成 ICC鑫椤钠电发布的统计数据显示，2025年，中国钠离子电池产量达到3.45GWh，相比2024年的1.76GWh接近翻倍。此外，近日有市场消息称，包括LG新能 源在内的国际巨头计划在南京建设钠电试点产线，试图利用中国成熟的供应链体系加速其钠电的商业化进程。 在锂电池的核心基础 ...

Core Viewpoint - The sodium battery industry is transitioning from concept validation to large-scale delivery, with significant advancements in production and cost reduction, positioning itself as a viable alternative in scenarios where lithium batteries are less effective [2][4][21]. Industry Developments - CATL launched a new series of sodium-ion batteries, including the industry's first mass-produced low-temperature version, achieving an energy density of 175Wh/kg [2]. - Jiangsu Zhongna Energy's sodium iron sulfate cathode material production facility has begun mass production, reducing the cost of sodium battery cells to approximately 0.45 yuan/Wh [5][6]. - By 2025, China's sodium-ion battery production is expected to reach 3.45GWh, nearly doubling from 2024 [4]. Cost and Economic Viability - The cost of sodium battery cells is projected to decrease further, potentially falling below 0.4 yuan/Wh by 2026, making them increasingly competitive with lithium batteries [6][7]. - Despite the cost reductions, challenges remain in achieving consistent material quality and production efficiency, particularly when scaling from laboratory to industrial production [8][9]. Unique Market Opportunities - Sodium batteries are finding unique applications in extreme temperature environments, such as low-temperature commercial vehicles and high-temperature conditions in regions like Saudi Arabia [13][14]. - In the two-wheeler battery swap market, sodium batteries offer longer cycle life compared to lead-acid batteries, leading to lower operational costs over time [16]. - The integration of sodium batteries in energy storage systems is evolving, with hybrid solutions combining lithium and sodium technologies to enhance efficiency [18][19]. Strategic Industry Positioning - The sodium battery sector is increasingly recognized as a strategic backup for energy security, with major players entering the market to leverage their supply chain capabilities [7][21]. - The industry is shifting towards a focus on long-life, lower-cost materials, with a significant portion of production expected to utilize stable, low-energy-density cathode materials by 2025 [22][24]. - The market is evolving to accept sodium batteries as a distinct product category rather than merely a cheaper alternative to lithium batteries, emphasizing their unique advantages in specific applications [10][11][24].
