摘要 硫磺暴涨300%，磷酸铁锂成本会被推高到哪儿？ 在锂电材料轮番涨价之后，化工圈 "黑马"硫磺也冲上舞台。 自2024年中以来，国产硫磺价格从不足千元涨至4000元/吨上方，涨幅超过300%，市场上迅速出现一种说法：作为磷酸铁锂、磷肥、钛白粉等多 个链条的共用原料，这轮"牛磺"行情将再次推高新能源电池成本。 问题在于，对已经经历三年亏损、刚刚酝酿涨价的磷酸铁锂行业而言，硫磺究竟是主矛盾，还是一项被放大的边际变量？ 硫磺价格四倍上涨，供需剪刀差推到台前 公开报价显示，自 2024年6月中旬至2025年12月初，国产固体硫磺港口价由约915元/吨一路攀升至4100元/吨左右，累计涨幅超过300%，已逼 近2022年高点，部分机构甚至喊出"冲击6000元/吨"的预期。 这一轮行情的直接驱动在于供需剪刀差：一端是中东等地合约价大幅上调、国内港口库存降至 "警戒线"，另一端是磷肥、钛白粉、高压酸浸镍 （HPAL）、锂电池等下游对硫酸需求持续扩张。 相关监测机构测算，2025年9月国产固体硫磺月均价已超过2500元/吨，此后在卡塔尔合约价上涨和国内刚需补库的叠加下，12月初长江、镇江等 港口现货报价突破4000元关口 ...
