前不久,在恩捷股份(002812)技术创新论坛上,公司正式发布了其5μm超薄锂电池隔膜产品。这是公司目前量产的"最薄"动力电池隔膜。 近日,证券时报·e公司记者探访恩捷股份玉溪基地,实地观摩了其5μm产品的生产流程,并就动力电池隔膜行业发展趋势,固态电池材料研发进程等,与公 司相关技术负责人进行了直接对话。 记者在现场看到,产线处于全封闭生产状态,仅有少量技术人员。 玉溪基地有关负责人表示,这个基地系恩捷股份5μm产品专属产线集群,按"灯塔工厂"标准设计施工,实现了产线的数字化、自动化和模块化,通过部署数 字化系统以及AI算法,实现数据实时监控与优化。基地合计规划16条产线,占地面积超过480亩,目前的月产能为1900万平方米。 锂电池隔膜是锂电池正负极之间的一层薄膜,其厚度仅为头发丝的十分之一。在锂电池进行电解反应时,隔膜能够分隔正负极,防止短路现象的发生,同时 允许电解质离子自由通过。作为锂电池四大材料之一,隔膜的成本约占锂电池成本的10%,是研发难度最大、技术含量最深、附加值最高、投资强度最大的 锂电池材料。 通常情况下,隔膜厚度的减少和强度提升是相悖的。程旭表示,公司此番通过结构调控、多机链协同等技术 ...
