摘　　要：在镉镍全密封蓄电池内部增加吸氧辅助电极———Ag Hg电极 ,同时采取两阶段充电控制等措施 ,从而成功地将地球同步轨道卫星镉镍蓄电池的第三电极信号电压充电控制方法应用于低轨道卫星上 ,不仅避免了低轨道卫星镉镍蓄电池大电流充电后期造成的极化对充电控制信号的影响 ,而且改善了充电后期效率 。Ag Hg electrode, the auxiliary oxygen absorbing electrode was added inside the hermetically sealed Ni Cd battery while the two step charging control method was adopted. Thus, the control method for the signal voltage charge to the third electrode of Ni Cd battery, which is used for GEO (geosychronous orbit) satellite, was applied in LEO (low earth orbit) satellite successfully. As the results, the detrimental effect of pola rization caused in the anaphase of large current charging to Ni Cd battery for LEO satellite on charge controlling signal is avoided, and the anaphase efficiency of charging is improved as well as the heat generation is decreased.
