星上二次电源—蓄电池是限制卫星、特别是通信卫星工作寿命的主要因素之一。众所周知,星上蓄电池的工作寿命取决于工作循环类型和蓄电池的种类。在过去二十年里,实际用作空间能源贮存设备的是氧化镍-镉蓄电池,银-氢、镍-氢以及燃料电池也起到了重大的作用。表1列出了各种空间 Onboard secondary power - battery is one of the main factors limiting the working life of satellites, especially communications satellites. As we all know, the working life of batteries on the planet depends on the type of work cycle and the type of battery. Nickel-cadmium batteries, silver-hydrogen, nickel-hydrogen, and fuel cells have also played a major role in the actual space energy storage equipment used over the past two decades. Table 1 lists the various spaces
