LAN负极在热电池中的应用

Application of LAN anode in thermal battery

研究了含锂质量分数为15%的LAN负极(Li-Ni);同时还与含锂质量分数为44.32%的LiSi合金和31%的LiAl合金作了对比。结果表明,Li-Ni的LAN负极电极电位比LiSi合金、LiAl合金的更负、工作电压更高,与FeS2正极配对时有电动势ELAN>ELiAl>ELiSi。LAN负极具有好的脉冲输出特性,脉冲电压ULAN>ULiAl>ULiSi。在带大电流密度负载激活时,LAN负极具备快速激活能力,激活时间tLAN<tLiAl<tLiSi。在大电流密度下放电,LAN负极的利用率较高,材料利用率ηLAN>ηLiAl>ηLiSi。LAN负极在结构设计合理的情况下可使热电池在径向2048.2m/s2离心力作用下正常放电。

The thermal battery LAN anode （Li-Ni） with lithium mass content of 15% was researched, and was compared with LiSi alloy with 44.32% Li and LiAl alloy with 31% Li. the results show that LAN （Li-Ni） anode has more negative emf than LiSi alloy and LiAI alloy, and ELAN〉ELial〉ELiSi. The LAN anode can output long-time high current impulse, and the impulse voltages can be shown as ULAN〉ULiN〉UUSi. When loaded current density is more than 1 A/cm^2, the thermal battery with LAN anode can be activated immediately, and the activating times can be shown as tLAN〈tLial〈tLiSi. When loaded with high current density, the material utilization rates can be shown as ηLAN〉ηLiAl〉ηLiSi. When the reasonable LAN anode structure designed, the activated thermal battery with LAN anode can sustain 2 048.2 m/s^2 radial centrifugal force, and the output voltage curve is very smooth.
