Abstract

The negative electrode of MH/Ni battery with nanometric cupric oxide additive was prepared. The changes of storage capacity and mass of LaNi₅ metal hydride electrode with nanometric CuO additive and the electrochemical performance of the electrode were investigated. Cyclic voltammograms and SEM results indicated that CuO was reduced during first charging process and copper particles were deposited on the surface of alloy. Electrochemical testing results showed that the electrode with additive had better rate capability and cycle performance. Electrochemical impedance spectroscopy analysis indicated that the electrode with additive had higher activity and electrical conductivity, and lower ohmic and electrochemical impedance, which can help to improve the electrochemical properties of the electrode.

Key words: nanometric copper oxide, nickel metal hydride battery, electrochemical performance, electric vehicle
