摘要
This paper describes a simple setup using a thin, insulated platinum wire as an in situ electrochemical probe for analysis of the soluble polysulfide intermediates formed and consumed during the course of the discharge process of a lithium-sulfur cell. The probe, sharing common reference and counter electrodes with the cell, can be used to follow the changes in concentration of polysulfides in the electrolyte. The results herein both support and complement more advanced techniques studied elsewhere for understanding the dominant processes occurring in the cell. (C) 2014 Elsevier B.V. All rights reserved.
