据路透社1月28日最新报道，汽车巨头大众汽车宣布，将在美国市场分两批召回共计44551辆大众ID.4纯电动车型，召回核心原因直指车辆搭 载的高压电池存在起火安全隐患，此次事件迅速引发全球汽车及锂电行业广泛关注。 据悉，本次两批召回虽涉及车辆批次略有差异，但均指向同一核心问题部件——高压电芯模块，且牵涉到同一家锂电巨头供应商——SK电池 美国公司（SK On）。作为大众北美市场电动化战略的核心电池合作伙伴，SK On此次被卷入召回风波，其产品质量稳定性再度成为行业聚 焦的焦点。 美国国家公路交通安全管理局（NHTSA）披露的调查文件显示，召回行动的启动源于多起安全事故隐患。2024年至2025年间，大众ID.4车 型在美国市场至少发生了5起电池过热相关事件，部分事件甚至出现起火苗头，给车主人身及财产安全带来潜在威胁。 为查明事故根源，大众汽车联合供应商SK On开展了全面的拆解分析工作。经技术团队排查确认，此次电池过热及起火隐患的核心诱因，是涉 事高压电芯模块存在"电极移位"这一硬件异常。据悉，所谓"电极移位"，是指因电池变形导致正极和负极发生错位，电池鼓包就是其表现形 式之一，属于电芯制造过程中需严格管控的关 ...
