| 仿真揭示了，放热条件可能导致热引燃。 在锂离子电池的开发过程中，安全设计与评估在预防热失控引起的着火等问题中发挥着重要的作用。我们使用模拟技术，如COMSOL Multiphysics来了解各种现象对锂离子电池的影响，评估电池的安全性。本文介绍了一种建模的方法来测试在锂电池里的化学反应放热的安全性。 “如果释放的热量比由内部和外部放热产生的热量大，电池将会是热稳定的状态。如果释放的热量少，温度就会稳步上升并导致热失控。” 我们的模拟着眼于使用热分析来评估热失控条件。考虑了三种放热形式： 使用加热箱和加速量热仪（ARC）的外部加热 化学反应（热降解反应，燃烧等）产生的内部热量，和 放热（热传导、辐射）。 如果释放的热量比由内部和外部放热产生的热量大，电池将会是热稳定的状态；如果释... |
