锌离子在水相介质Zn/V_2O_5二次电池中的迁移性能研究

Studies on the Transport Properties of Zn^2+ in the Zn/V_2O_5 Secondary Battery with Aqueous Medium

利用间歇性恒电流测定法和ＸＲａｙ衍射法，研究水相介质的Ｚｎ／Ｖ２Ｏ５二次电池中的锌离子在正极材料中的迁移性能及其放电机理；讨论锌离子在正极材料中发生迁移时的某些动力学参数与放电深度的关系．实验结果表明，该电池的正极放电反应为锌离子在ＺｎｘＶ２Ｏ５中的嵌入过程．

The transport properties and the reaction mechanism of Zn^2+ in the cathode material of Zn/V_2O_5 secondary battery with aqueous medium were studied by use of intermittent titration experiments and X-Ray diffraction analysis. The relations of some kinetic parameters to the discharge depth were discussed. The results of the experiments show that the cathodic discharge reaction is an intercalation process.
