摘　　要：镍电极的填充方式主要有化学浸渍、电化学浸渍两种,采用电化学浸渍工艺制成的镍电极具有活性物质利用率高、电极能量保持能力强、电极使用寿命长等优点,而长寿命是航天器用储能电源最重要的一个指标。国内对于电化学浸渍法的研究取得了较大进步,但还鲜有在轨运行的相关报道。对采用电化学浸渍法制备的空间镉镍电池,模拟空间在轨运行的充放电制度,对电池进行长期的循环寿命测试,为电化学浸渍法在空间型号上的应用提供数据支撑。The filling ways of nickel electrode mainly include chemical impregnation and electrochemical impregnation. The nickel electrode prepared by electrochemical impregnation process has the characteristics of high utilization of active material and electrode energy retention ability, and long service life. Of all these characteristics, long service life is one of the most important indicators of the storage power for space application.The study on electrochemical impregnation method have made great progress in the domestic, but the application in space is seldom reported. The long-term cycle life of cadmium nickel battery for space application prepared by electrochemical impregnation was studied,and in-orbit charging and discharging system was simulated. This provide a powerful data support for the space application.
