1. **电池热失控风险**:机械滥用(碰撞、变形)、电气滥用(过充、过放)、热滥用(高温)均可能导致热失控,引发爆炸或火灾。 2. **应用场景广泛**:涉及运输(RO-RO船、汽车运输)、停车场、住宅(电池墙、公寓)、仓库等,需针对性安全措施。 3. **热失控过程**:分阶段描述,包括加热开始、持续加速、排气(快速/缓慢)、热事件(爆炸/无火燃烧)及二次事件。 4. **残留物分析**:XRF检测到Ni、Mn、Co(正极材料)、Al(集流体)、Cu(负极集流体)等元素;FTIR推断出Li₂CO₃、Li₃PO₄、PVDF粘合剂残留及金属氧化物(NiO、Co₃O₄)。 5. **安全研究方向**:开发储能系统表征、风险监测仪器、失效模拟、灭火系统测试及火灾污染物分析。
