【摘要】 研究了锂的质量百分数为61%的Li(B)合金和15%的LAN负极(Li-Ni)。结果表明,Li(B)合金与LAN负极电极电位相同。Li(B)合金负极具有好的脉冲放电特性,脉冲电压ULi(B)>ULAN。在大电流密度放电条件下,Li(B)合金与LAN负极都具备快速激活能力,性能相近。在各种电流密度下放电,Li(B)合金的利用率都比LAN负极高。Li(B)合金中吸附的金属锂能够全部放电,而且组成Li-B化合物纤维基体的锂有超过30%的锂也可以放电。如果负极结构设计合理,用Li(B)合金和LAN的热电池可在径向2048.2m/s2离心力作用下正常放电。Li(B)合金的各种物理性能和抗氧化性优于LAN,Li(B)合金的相对成本只有LAN(Li-Ni)负极的60%。更多还原

【Abstract】 The anodes of thermal battery with 61%-lithium boron alloy and 15% Li-Ni lan were studied. the results show that the lithium boron alloy anode and lan anode have the same potential. The lithium boron alloy and lan anode can output long-time high current impulse, and the relationship of impulse voltage can be shown as ULi(B)>ULAN. When loaded current density is more than 1 A/cm2, the thermal battery with lithium boron alloy and LAN anode can be activated immediately, and their activation times are almost the same. When loaded with any current density, the lithium boron alloy’s utilization rate is higher than LAN anode. The freedom lithium adsorbed by the lithium boron compound fibers can discharge completely, and the lithium constituted the lithium-boron compound fibers can discharge nearly more than 30%. When the reasonable anodes structure of lithium boron alloy and LAN are designed, the activated thermal batteries can discharge normally at radial centrifugal force 2 048.2 m/s2. The lithium boron alloy’s mechanical properties are superior to LAN anode, and its anti-oxidation property is also superior to LAN anode. When used in the thermal batteries, the relative cost of the lithium boron alloy is only 60% of the LAN- (Li-Ni) anode.更多还原
