摘　　要：为研究锂氟化碳电池在火星探测应用中的环境适应性,设计并实施了辐照实验、空间环境力学实验、火星表面极低温度贮存实验等多种空间环境适应性评价实验。结果表明,锂氟化碳电池经受20 k rad(Si)剂量的辐照后,容量损失<1.5%,电池组经受30 g加速度、1800 g冲击力学后结构完整、无明显形变,过程中电池电压无跳变,电池经受极低温度再恢复常温后仍具备正常放电能力,容量损失为2.99%。In order to study the environmental adaptability of lithium fluoride carbon battery in Mars exploration application,a variety of space environmental adaptability evaluation tests,such as irradiation test,space environmental mechanical test,Mars surface extremely low temperature storage test,were designed and implemented.The results show that the capacity loss of Li/CFx battery is less than 1.5%after 20 k rad(Si)dose irradiation.The battery pack has complete structure and no obvious deformation after being subjected to 30 g acceleration and 1800 g impact mechanics,especially the battery voltage has no jump during the process.The unit battery still has normal discharge capacity after being subjected to extremely low temperature and then restored to normal temperature,and the capacity loss is 2.99%.
