Abstract: The electrochemical behavior of electrodes based on germanium nanowires in an electrolyte containing 1 m LiClO₄ in a propylene carbonate–dimethoxyethane mixture (7 : 3) with 2 wt% vinylene carbonate (VC) was studied. The additive of VC in this electrolyte decreased the irreversible capacity, increased the reversible capacity, and decreased the degradation rate of germanium electrodes in the course of cycling.

Keywords: germanium nanowires, vinylene carbonate, irreversible capacity, solid electrolyte interface, degradation, electrochemical impedance.
