多级热响应气凝胶用于电池模组全周期热防护并抑制热失控蔓延
Multistage Thermally Responsive Aerogel for Full‐Cycle Thermal Protection in Battery Modules to Prevent Thermal Runaway Propagation
AI 导读
研究设计了一种多级热响应气凝胶，用于锂离子电池模组全周期热失控防护。在可控阶段，气凝胶释放水蒸气，将理论氧摩尔分数降至4.07%，并可通过局部湿度变化实现预警；在不可控阶段，Co-BDC辅助分解持续释放阻燃气体，同时触发原位陶瓷化反应，在表面生成致密陶瓷层。
推荐理由
原文按热失控的可控与不可控阶段拆解防护需求，给出释水、产气与原位陶瓷化三层响应及压缩强度变化。
