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.
