锂电池可回收有机硅胶包装设计及其性能分析

目的 针对目前锂电池包装密封性差，正负极容易被潮湿环境损坏的情况，设计一种内包装采用HL-1029有机硅胶包裹锂电池，外包装用瓦楞纸盒包装的结构。方法 根据锂电池型号及尺寸计算HL-1029包裹体厚度，建立包装件三维模型，在有限元环境中分析3 500 mm码垛高度以及1 200 mm跌落高度下，瓦楞纸箱、瓦楞纸隔板、HL-1029包裹体以及锂电池的应力云图。结果 3 500 mm码垛高度以及1 200 mm跌落高度下，锂电池所受的静应力和等效应力分别为0.03 MPa和8.80 MPa，锂电池所受静应力和等效应力均未超出其材料的屈服强度。结论 综合有限元分析结果，HL-1029包裹体可为锂电池运输过程中提供充分的防护，并且具有极高的可循环性。研究可为锂电池以及精密电子元器件的密封性包装提供研究思路。

Design and Performance Analysis of Recyclable Silicone Gel Packaging for Lithium Battery

The work aims to design a structure of HL-1029 silicone gel wrapping lithium battery inside and cardboard box packaging outside to deal with the poor sealing of lithium battery packaging and the fact that the positive and negative poles are easy to be damaged in a wet environment. The thickness of the HL-1029 package was calculated based on the model and size of the lithium battery. A packaging model was established. And the stress patterns of the corrugated cardboard box, corrugated paper partition, HL-1029 package, and lithium battery under a stacking height of 3 500 mm and a drop height of 1 200 mm in a finite element environment were analyzed. At a stacking height of 3 500 mm and a drop height of 1 200 mm, the static stress and equivalent stress of the lithium battery was 0.03 MPa and 8.80 MPa, respectively. It was found that the static and equivalent stress on the lithium battery did not exceed the yield strength of the material. Based on the comprehensive finite element analysis results, the HL-1029 package can provide sufficient protection for the transportation of lithium batteries and has exceptionally high recyclability. The research can offer research ideas for the sealing packaging of lithium batteries and precision electronic components.
