当单颗电芯因穿刺、过充或内部短路引发热失控时,其温度可在0.1秒内飙升500℃以上,如同微型炸弹。更危险的是,这种高温会以每秒1-2个电芯的速度向 四周扩散,引发连锁反应。 2025年4月,工信部发布的GB 38031-2025犹如一柄达摩克利斯之剑悬挂在整个行业头顶。传统方案仅能提供5分钟逃生时间,而新国标要求:电池包必须在 单体热失控后2小时内不起火、不爆炸,且所有监测点温度≤60℃。要求提高了24倍,这直接催生了百亿级的高端隔热材料市场。 气凝胶作为目前已知导热系数最低的固体材料,凭借0.015-0.019W/(m·K) 的超低导热系数(仅为空气的一半),成为当前最有效的隔热材料 。 气凝胶主要 用于电芯之间以及电池模组、PACK的上盖采用防火隔热材料 , 有效减少因电池问题导致起火的事故,阻止动力电池热失控蔓延。以比亚迪为代表的多家动 力电池企业,逐步选用预氧丝气凝胶隔热片、陶瓷气凝胶隔热片作为电芯之间的动力电池用隔热材料,以降低新能源汽车燃烧风险,提高驾驶性。 新国标实施后行业将迎来洗牌,提前布局安全技术的企业已抢占先机。 以下众多国内外知名企业 ,将出席参与 2025年12月3-5日 ,在深圳国际 ...
