一家磷酸铁锂上市公司人士对上海证券报记者分析，预计2026年有条件的电池企业会继续向第四代磷酸铁锂材料切换。该 材料主要将落地相对高端的车型。与需求增长形成对比的是，目前四代磷酸铁锂材料产能不到200万吨，出现明显紧缺。因 此，2026年该材料预计出现阶段性供不应求。 3月5日晚，比亚迪董事长兼总裁王传福在"比亚迪第二代刀片电池暨闪充技术发布会"上重点介绍，公司新推出的第二代刀 片电池5分钟"充好"，9分钟"充饱"。即电池从10%到70%的充电用时仅5分钟，从10%到97%的充电用时仅9分钟。王传福还 介绍了第二代刀片电池在低温充电性能上的突破。 有市场观点认为，这代表着比亚迪突破了磷酸铁锂电池新的技术边界。 上海证券报记者从锂电产业链获悉，第二代刀片电池使用了第四代磷酸铁锂材料。作为磷酸铁锂行业可量产的最新一代材 料，第四代磷酸铁锂对电池能量密度、倍率性能（与快充性能相关）、低温性能等关键指标均起到重要支撑作用。 SMM分析，2025年，全国仅有约4—6家企业实现四代磷酸铁锂稳定生产且批量出货。2025年，四代产品在所有磷酸铁锂产 品中的产量占比约10.3%。2026年，为匹配储能大电芯与高能量密度动力电芯 ...
