In order to improve the safety performance of 18650 lithium battery in storage and transportation, the thermal runaway expansion research of nine-palace grid glass fiber partition packaging was studied by experiment and computational simulation. The results show that the glass fiber partition with a certain gap between the batteries and the partition can effectively inhibit the thermal runaway expansion of lithium battery. The optimal distance between the battery and the partition is 2.2 mm, and the thickness of the partition is 1.2 mm. Under the optimal condition, the highest temperature near the surface of the battery is only about 130. The safety and protection performance of a lithium battery can be significantly improved by using the optimized glass fiber partition packaging.

为了提高18650锂电池在储运中的安全性能，通过实验和计算仿真研究了九宫格玻璃纤维隔断包装的热失控膨胀研究。结果表明，玻璃纤维隔板在电池与隔板之间具有一定的间隙，可以有效抑制锂电池的热失控膨胀。电池与隔板之间的最佳距离为2.2毫米，隔板的厚度为1.2毫米。在最佳条件下，电池表面附近的最高温度仅为130左右。通过使用优化的玻璃纤维分隔包装，可以显着提高锂电池的安全性和保护性能。
