摘要:
为解决不溶性放电产物Li 2O 2在Li O 2电池(Lithium oxygen batteries,LOBs)阴极表面的积累问题,采用晶体工程技术制备集流体碳纸(Carbon paper,CP)与单金属Cu MOF 74/CP、Ni MOF 74/CP及双金属Cu x Ni y MOF 74/CP复合阴极材料。将所制备的材料作为Li O 2电池阴极并对其进行电化学性能测试。结果表明:双金属MOFs阴极通过Cu和Ni之间的协同作用增加了反应活性位点,显著提升了电子传输速率;Cu 1Ni 1 MOF 74/CP阴极表现出最低的电荷转移电阻(121 3 Ω)和最高的放电比容量(6083 7 mAh/g),并能在500 mAh/g截止比容量条件下稳定循环35次。该研究拓展了MOFs在电化学能源存储领域的应用,也可为开发高性能Li O 2电池提供了一定的理论和实验支持。
