固态电池高聚物电解质的高温高湿蠕变仿真与实验研究OACHSSCDCSTPCD

Polymers are extensively applied in solid-state batteries.Different from traditional metallic materials,the material mechanics and creep behavior of polymer material are particularly special under high-temperature and high-humidity environments.In this thesis,creep experiments are conducted on a polymer material under high-temperature and high-humidity environments,and its creep characteristics are analyzed based on the modi-fied Burgers model.The creep calculation of polymer materials under high-temperature and high-humidity envi-ronments is implemented in ABAQUS finite element software.The results show that the numerical simulation results are in good agreement with the experimental results,verifying the accuracy of the creep constructive model based on the modified Burgers model in describing the creep behavior of polymer materials under high-temperature and high-humidity environments.
