钠离子电池的原材料价格走势如何？

What is the price trend of sodium-ion battery raw materials?

钠离子电池核心原材料分为钠源、正极前驱体、硬碳负极、电解液钠盐、铝箔辅料五大类，2023 至 2027 年整体呈现短期小幅波动、中长期持续下行的价格走势，核心驱动为国内万吨级产线集中投产、原料矿产供给充足。钠源（纯碱、工业盐）：矿产储量极丰富，全球产能过剩，价格常年稳定低位，无大幅上涨空间，波动幅度仅 5%-10% 区间。普鲁士蓝前驱体：2024 至 2025 年多条万吨产线落地，原料铁锰矿供应充足，价格同比下降 35%；2026 年后产能饱和维持低位震荡。聚阴离子钒源：短期钒矿小幅波动，中长期国内钒渣回收产线放量，钒原料价格逐步回落，配套钒基正极成本持续下滑。硬碳负极：农林生物质原料成本极低，随碳化产线规模化量产，硬碳均价每年下降 12%-18%，2027 年规模化后成本下探至当前六成。电解液钠盐 NaPF6、NaFSI：钠盐合成工艺成熟，产能扩张后价格持续走低，NaFS 高端盐降幅超 40%。铝箔、导电剂、粘结剂配套辅料供给宽松，跟随锂电产业链同步小幅降价。对比锂矿数年暴涨暴跌，钠电池全部核心原料无稀缺矿产约束，不存在地缘供给风险，长期价格中枢稳定下行。行业机构测算，2027 年完整钠电芯原材料综合成本较 2024 年下降 48%，价格下行将持续打开储能、低速车市场普及空间。

Core sodium-ion battery raw materials include sodium sources, cathode precursors, hard carbon anodes, sodium electrolytes and aluminum foil auxiliaries. From 2023 to 2027, prices see mild short-term fluctuation and sustained medium-long term decline, driven by concentrated commissioning of domestic ten-thousand-ton lines and sufficient mineral supply. Sodium sources (soda ash, industrial salt): extremely abundant global mineral reserves lead to permanent low stable prices with only 5%~10% fluctuation and no sharp upside. Prussian blue precursors: multiple ten-thousand-ton lines launched 2024~2025 with sufficient iron & manganese ore supply, cutting prices 35% year-on-year and oscillating at low levels after 2026 capacity saturation. Vanadium sources for polyanions: mild short-term ore fluctuation, followed by gradual price decline as domestic vanadium slag recycling lines expand to lower vanadium cathode costs year by year. Hard carbon anodes: ultra-low biomass feedstock cost, with average annual price drop of 12%~18% via scaled carbonization lines, falling to 60% of current cost by 2027. Sodium salts NaPF6 & NaFSI: mature synthesis and capacity expansion drive continuous price decline, with over 40% drop for high-end NaFSI. Sufficient supply of aluminum foil, conductive agents and binders brings moderate synchronous price reduction alongside lithium chains. Unlike volatile lithium ore, all core sodium raw materials face no scarce mineral or geopolitical supply risks with steadily falling long-term price centers. Industrial institutions estimate comprehensive cell raw material costs will drop 48% by 2027 vs 2024, continuously expanding market penetration for energy storage and low-speed vehicles.
