锂电池化成工艺曲线解读：SEI 膜形成机理和首次效率
锂电池制造有一个工序，不涉及任何机械加工，不产生任何物理形变，但直接决定了电芯的循环寿命、存储性能和安全性。这个工序就是化成。 化成是电芯注入电解液后的第一道通电工序。在这个阶段，电解液中的溶剂和锂盐在负极石墨表面发生还原反应，生成一层 10-50 nm 厚的钝化膜——SEI 膜（Solid Electrolyte Interphase，固体电解质界面膜）。这层膜的质量决定了电芯未来 3000-5000 次循环中的容量衰减速度。 换个说法：极片做得好不好决定了电芯的”出厂性能”，化成的质量决定了电芯的”耐久性能”。 这篇文章从曲线解读入手，把化成工艺的核心逻辑讲清楚。 化成到底在做什么？ 新注液的电芯静置 24-48 小时（电解液浸润）后，开始首次充电。此时负极石墨处于完全脱锂状态，电位约 3.0V vs Li/Li⁺。随着充电进行，锂离子从正极脱出，穿过隔膜，嵌入负极石墨层间。 但事情没这么简单。电解液中的碳酸酯溶剂（EC、EMC、DMC
