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.
