Electrochemical behaviors and reaction mechanism of nanosilver with lithium

Abstract

The electrochemical behavior of Ag with Li was investigated with various particle sizes and under different current densities. When tested at a current of 10 mA g-1, the electrochemical behavior of a nano-Ag electrode showed a highly reversible reaction with Li, with the first discharge and charge capacities being 1158 and 727 mAh g-1, respectively. The electrochemical reaction mechanism of Ag alloying/dealloying with Li was revealed by ex situ X-ray diffraction analyses combined with a differential capacity plot of the nano-Ag electrode. © 2009 The Electrochemical Society.
