Test Research of High Specific Energy Lithium Carbon-Fluoride (Li/CFx) Batteries as Power Sources for Deep Space Exploration

  • 摘要: 深空探测任务由于重量制约以及光照强度减弱等原因,可供选择的电源有限。锂氟化碳电池技术被认为是未来深空探测器电源潜在可行的选项。对锂氟化碳电池进行了比能量、比热容、发热量测试以及低温性能和贮存性能测试,测试结果表明:锂氟化碳电池高比能量优势明显,长贮存寿命满足了深空探测器数月甚至数年飞行期间自放电率低的需求,针对低温应用需求,采用复合电极有效改善低温放电性能,而针对锂氟化碳电池比热容、发热量的测试为电池热仿真分析提供了必不可少的数据支撑。

     

    Abstract: Deep-space exploration missions have limited power options due to weight constraints and reduced light intensity. Lithium-fluorocarbon battery technology is considered a potentially viable option for future deep space probe power supplies. Tests on specific energy, specific heat capacity, calorific value, and low temperature and storage performance of lithium fluorocarbon batteries were carried out. The results show that lithium fluorocarbon batteries have obvious advantages of high specific energy. Its long storage life meets the needs for deep space probes with low self-discharge rates during months or even years of flight. For low-temperature applications, the low-temperature discharge performance is effectively improved by the use of composite electrodes. The trials of specific heat capacity and heat generation for lithium-fluoride carbon batteries provide essential data support for battery thermal simulation analysis.
