气凝胶被誉为"凝固的烟"，是目前已知导热系数最低的固体材料。它是一种由纳米级微粒相互聚集构成的轻质多孔材料，孔隙率高达90%以上，赋予了其 0.015-0.019W/(m·K)的超低导热系数，仅为空气的一半。 合成工艺主要包括三个核心步骤：首先通过溶胶-凝胶法制备湿凝胶，形成三维网络骨架；然后经过溶剂交换，用低表面张力液体替换孔隙中的溶剂；最 后通过干燥技术（超临界干燥或常压干燥）在保持骨架结构的前提下将液体抽出，形成多孔气凝胶。其中超临界干燥能最大限度避免毛细管力导致的孔结 构塌陷，但设备投资巨大，是目前产业化的主要瓶颈。 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。除动力电池热管理 外，气凝胶也广泛应用于其他领域，在建筑节能领域，作为超薄隔热涂料和保温板材；在石油化工领域，气凝胶毯用于深海管中管隔热、炼油设备和 LNG储罐，耐温范围覆盖-196℃至650℃；在航空航天领域，利用其超轻特性和吸能能力，用于航天器热防护、低温燃料储罐绝缘以及飞机发动机短舱隔 热。 2025年4月，工信部、住建部、应急管理部、市场监管总局、国家消防救援局 ...
