摘要：
The effective use of a magnesium anode in power sources with a non-aqueous electrolyte strongly depends on the properties of the interface between the surface of the magnesium electrode and the non-aqueous electrolyte. In order to optimize electrochemical characteristics of magnesium electrode in the given electrolytes and, as a consequence, to optimize the power source in general, the impedance and galvanic characteristics of the magnesium electrode have been investigated. The electrochemical properties of anode based on magnesium foil and magnesium electrode with a porous structure have been compared. Electrodes with a porous structure have been made using magnesium shavings. The impedance characteristics of the magnesium electrode have been determined in dependence to the composition of the electrolyte, the value of the currents of galvanostatic anodic dissolution, and the storage time after galvanostatic anodic dissolution also determined. The influence of anodic dissolution mode on the impedance spectrum of a magnesium electrode has been investigated. It has been found that absorbing formed films after anodic decomposition exhibit higher conductivity than films formed without actuation. (C) 2018 Elsevier Ltd. All rights reserved.
