【摘要】 为了获取纳米复合电解质材料更高的输出功率和更久的稳定运行时间,采用碳酸盐共沉淀的方法分别制备了SDC(Ce_0.8Sm_0.2O_1.9)和1.2倍碳酸钠的NSDC（SDC-Na₂CO₃）纳米复合电解质并进行了分析比较。结果表明:NSDC电解质电池开路电压最高可达0.87 V,瞬时最大功率密度能够达到450 mW/cm²,在相同温度下性能相比纯SDC电解质电池有很大提高;在掺入一定比例LCNC(Li_1.2Co_0.2Ni_1.5Cu_0.1O₃)后,NSDC电解质电池稳定工作时间可以达到9 h,并能快速进入稳定工作状态,但电压并无明显提升。更多还原

【Abstract】 To improve the power output and to elongate the stable running time of nano-composite electrolyte materials, SDC(Ce_0.8Sm_0.2O_1.9) and 1.2 times excess sodium carbonate NSDC（SDC-Na₂CO₃） composite were prepared by carbonate co-precipitation method, for which, comparative analysis was conducted. Results show that the open circuit voltage of a pure NSDC electrolyte battery may reach 0.87 V, with a maximum instantaneous power density up to 450 mW/cm², and a higher performance than that of a pure SDC battery at same temperatures. After being mixed with a certain proportion of LCNC(Li_1.2Co_0.2Ni_1.5Cu_0.1O₃), the stable working time of NSDC electrolyte battery can reach 9 h, which is able to quickly enter a stable working state, when the voltage is not improved significantly.更多还原
