| 摘 要： | 研究Li-B合金作为负极对锂(Li)/亚硫酰氯(SOCl_2)电池性能的影响。采用Li-B合金可提高Li/SOCl_2电池的工作温度范围,最高工作温度为250℃,且电池在150℃以上时以0.1 C倍率工作,电压平台不低于3.6 V;SEM分析表明:金属锂表面由丝状团簇的锂所组成,Li-B合金由Li_7B_6和Li共同组成;同步热分析表明:Li-B合金具有更好的热稳定性;电化学阻抗谱测试表明:与Li负极相比,Li-B合金负极具有较大的传荷电阻,即具有较低的反应活性。

| Abstract: | Effects of Li-B alloy as cathode to the performance of lithium (Li)/thionyl chloride (SOCl2) battery were researched.The operating temperature range of Li/SOCl2 battery was improved by Li-B alloy and the maximum operating temperature could reach to 250 ℃.When the battery was discharged in more than 150 ℃ with 0.1 C rate,its voltage platform could maintain above 3.6 V.SEM analysis indicated that,the filamentous cluster of Li surface was composed of lithium,the Li-B alloys was composed of Li7 B6 and Li.Simultaneous thermal analysis showed that Li-B alloy had better thermal stability.The Li-B alloy cathode had a larger charge transfer resistance than Li by the electrochemical impadance spectroscopy test.The Li-B alloy was exhibited a lower reactivity. |
