Application of Gas Atomised MmNi4,3Al0,2Mn0,5 Alloy as Material of the Negative Electrode in Ni-MH Batteries
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 2
Abstract
The electrochemical properties of the gas atomised MmNi4,3Al0,2Mn0,5 alloy electrodes such as activation rate, discharge capacity and high rate discharge ability have been investigated. Determined using electrochemical impedance spectroscopy total resistance of the electrodes are in good agreement with those calculated from other electrochemical dependencies. It is shown that the use of lightweight carbon nanocomposite as the electrode conductive additive slightly reduces the discharge capacity of the electrode and the electrode reactions kinetics compare to the electrode with copper additive. The corrosion stability of the electrodes in alkaline electrolyte has been studied.
