掺Pb改性MnO的制备及性能研究

The preparation and performance of MnO doped with Pb

通过在N2 下对掺Pb的MnC2 O4或MnCO3 热分解 ,分别制备了改性的Pb MnO。利用X射线衍射 ,循环伏安 ,充放电测试等实验对其进行了电化学性能的研究。结果表明 :Pb MnO可以提高其充放电性能 ,提高电极的可逆性 ,且Pb的掺入有益于延长第 1电子当量放电。对于以不同前驱体分解所得的Pb MnO 。

The different Pb MnO was prepared by solid state thermal decomposition of MnC 2O 4 or MnCO 3 method respectively.The characterization and electrochemical performance were studied by X ray diffraction ,cyclic voltammetry and charge discharge tests.It was shown that the performance of charge discharge of Pb MnO was improved by doping Pb and Pb played a role to increase the first electron equivalent discharge capacity.For different Pb MnO prepared from different precursors,the product from MnC 2O 4 was better.
