iPhone电池革新背后的检测“革命”

摘要 CT在线检测设备成为苹果手机电池产线升级的核心刚需。 随着苹果 iPhone 16 将电池封装从软包升级为钢壳,一场锂电池 智造 的变革正在悄然发生。 溯源变革的源头,钢壳 表面 相较铝塑膜 硬度更高,对电芯拥有更好的保护程度,并具备一定的散热改善效果 , 提升电池电芯密度 5 % -10% 。 更重 要的是, 降低拆卸电池的难度 能够 符合欧盟 的政策 规范 。 然而钢壳电池的引入, 也 直接推动 了 产线向高精度、 全 自动化 的 方向深度转型。传统软包电池的生产工艺以柔性化装配为主,而钢壳电池在电芯 封装、极耳焊接、壳体密封等环节对精度的要求提升至 0.1mm 级。 以极耳焊接为例,钢壳电池的极耳与壳体焊接点需要承受更高的电流负载,焊接缺陷可能导致短路或断路,因此必须 100% 检测焊接完整性。 检测环节 更是 成为技术变革的核心痛点。 据悉, 钢壳电池的检测新增了三大核心需求: 一是焊接质量检测 ,需要识别微米级的虚焊、焊穿等缺陷; 二是泄压阀功能检测 ,钢壳上的泄压结构必须在过压时精准启动,传统目视检测无法满足可靠性要求; 三是内部结构检测 ,极片弯折、异物混入等内部缺陷在钢壳封装后难以通过常 ...
