基于形状记忆传感复合材料的非侵入式压力传感器用于圆柱电池早期热失控预警
Non‐Invasive Smart Pressure Sensor for Early‐Stage Thermal Runaway Warning for Cylindrical Batteries
AI 导读
研究报道了一种基于形状记忆传感复合材料的非侵入式智能压力传感器，可与圆柱电池侧壁共形接触，连续监测充放电过程中体积膨胀引起的侧向压力。
推荐理由
该传感器以形状记忆传感复合材料贴合圆柱电池侧壁，给出多体系热失控预警时间占比，可作为电池安全监测方案参考。
创新点
将形状记忆传感复合材料用于圆柱电池非平面侧壁的共形压力监测，并通过 COMSOL 模拟设计装配工艺以抑制多层结构中的应力不均，从而在多种圆柱电池体系上实现早期热失控预警。
