摘要
采用化学方法制备AgO,并组装成实验电池。通过恒电流放电技术研究了在4 mol/L NaOH电解质溶液中加入不同浓度的NaAlO2对Al/AgO电池性能的影响,并考察了放电倍率和温度对Al/AgO电池性能的影响。用扫描电子显微镜(SEM)研究了电池放电前后AgO的表观形貌。结果表明:在NaOH溶液中加入适量NaAlO2可以提高电池的比容量。随着温度的提高,电池的比容量增大。随着放电倍率增加,电池的比容量降低。当NaAlO2浓度为2.5 mol/L,温度为80℃时,以0.1 C放电,终止电压为1.0 V时,Al/AgO电池的比容量达到292mA.h/g。
AgO was synthesized by chemical method and assembled into test battery. Influence of the NaAlO2 con- centration in 4 mol/L NaOH solution, discharge rate and temperature on the properties of Al/AgO battery in 4 mol/ L NaOH has been studied by means of measurements of contanst current discharge. The surface performance of AgO electrode before and after discharge has been studied by SEM. The results show that., the addition amount of NaAlO2enhances the specific capacity of Al/AgO battery. As temperature rising, the specific capacity of Al/AgO battery increases. When NaAIOz concentration of 2.5 mol/L at 80℃, dischargeing at 0.1 C, ending discharge volt- age of 1.0 V, the specific capacity of Al/AgO battery can reach to 292 mA · h/g.
