摘要: 直充式核电池具有工作寿命长、结构简单、开路电压高、易微型化等优点，具有广泛的应用前景。目前，国内外对直充式核电池同位素源的选择多集中在同位素β源，尚未对不同同位素β源进行系统的分析对比。针对此问题，通过理论计算及SuperMC建模处理，研究了³H（Ti³H₂）、¹⁴C，³⁵S，⁴⁵Ca，⁶³Ni及¹⁴⁷Pm六种固态同位素β源对直充式核电池的能量转换效率及理论输出功率的影响。结果显示，能量转换效率随源衰变粒子平均能量的升高而增大；理论输出功率及功率密度与源半衰期成反比。综合工作寿命、输出功率及能量转换效率，建议选用¹⁴⁷Pm同位素源。

Abstract: Direct charge radioisotope battery having the advantages of long service lifetime, simple structure, high open circuit voltage and easily miniaturized, is a promising source for the great power of Micro-ElectroMechanical System. Although the beta sources are the main choice for direct charge nuclear battery in the present studies,but no systematic analysis and comparison on beta sources is presented. In this work, the properties of six beta sources (including ³H(Ti³H₂), ¹⁴C, ³⁵S, ⁴⁵Ca, ⁶³Ni and ¹⁴⁷Pm) were studied by software simulation and theoretical calculation. This study includes the differences of energy conversion efficiency and the theoretical output power for direct charge nuclear battery. The calculated results showed that the energy conversion efficiency was positively correlated with the average energy of emitted radioactive particles, and the theoretical output power was negatively correlated with half-life of beta source. ¹⁴⁷Pm was the preferred choice considering long life, the energy conversion efficiency and the theoretical output power.
