摘要
K2FeO4是一种新型的绿色化学电源材料。为了研究其作为正极材料使用的可行性,我们采用可见光分光光度法对K2FeO4在碱性水溶液中的溶解度和稳定性进行了测试。研究表明:(1)在饱和的KOH溶液中K2FeO4的溶解度达到了可以接受的程度;(2)在碱性溶液体系中,碱液浓度、温度、碱液种类以及ZnO的添加对K2FeO4的稳定性均有影响,但在诸多因素中,主要还是碱液的浓度对K2FeO4的稳定性影响最大;(3)K2FeO4在饱和KOH溶液内有较低的溶解度和较好的稳定性,基本可以达到在电池中使用的程度,使K2FeO4作为一种新型的正极材料成为可能。
K2FeO4 is a new green material for chemistry power supply. For studying the feasibility as positive material. The stability and the solubility of K2FeO4 in the alkaline aqueous solution were examined by spectrophotometry method. The results show that: (1) the solubility of K2FeO4 in saturated KOH solution is acceptable; (2) the stability of K2FeO4 in alkaline aqueous solution is mainly influenced by the alkaline concentration compared with alkaline temperature, alkaline style and ZnO addition; (3) K2FeO4 can be basically used in battery as a new kind of positive material with low solubility and good stability in saturated KOH solution.
