摘要

目的研发可以解决废旧锂电池安全储运的包装箱。方法根据P911和LP906的包装要求,明确防爆包装箱的技术要求,通过试验确定基础材料及部件,设计建立废旧锂电池防爆包装箱模型,打样完成后,按照GB 38031—2020的触发热失控测试方法进行试验测试,通过试验过程数据、结果数据及试验结束后的开箱情况综合分析方案效果。结果热失控扩散试验过程中,无迸射物及火焰析出,箱体外表面（不含箱底）温度未超过100 ℃,开箱检查泄压结构未阻塞,箱体结构无异常,该包装箱能有效抑制热失控现象,基本满足国际海运危险货物规则中P911和LP906的包装要求。结论防爆包装箱可以有效解决废旧锂电池的安全运输问题,研究及测试结果为废旧锂电池的安全储运及回收提供重要参考。

Abstract

The work aims to develop a packaging solution that ensures the safe storage and transportation of waste lithium batteries. Based on the packaging requirements of P911 and LP906, technical specifications for an explosion-proof packaging container were defined. The foundational materials and components were determined through experimental testing, and a prototype of waste lithium batteries packaging containers was designed and fabricated. After sample production, thermal runaway trigger testing was conducted in accordance with GB 38031-2020. The effectiveness of the solution was comprehensively analyzed according to test process data, result data, and post-test inspection status of the container. During the thermal runaway propagation test, no ejections or flames were observed, the external surface temperature of the container (excluding the bottom) did not exceed 100 °C, the pressure relief structure remained unobstructed upon inspection, and the container structure showed no abnormalities. The packaging container effectively suppressed thermal runaway phenomena and largely met the packaging requirements of P911 and LP906 under the International Maritime Dangerous Goods (IMDG) Code. In conclusion, the explosion-proof packaging container provides an effective solution for the safe transportation of Waste lithium batteries. The explosion-proof packaging container provides an effective solution for the safe transportation of waste lithium batteries, and the research and test results provide significant references for the safe storage, transportation, and recycling of waste lithium batteries.
