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.
