Abstract

There is a growing interest in developing lithium-sulfur batteries (LiSBs) due to their high specific energy capacity, low manufacturing materials, and robustness. However, the operation of these batteries is mainly limited by the shuttle effect and dendrite growth on the sulfur cathode and lithium anode, respectively. This review examines different operando techniques to understand these issues better. In situ and operando characterization techniques complement electrochemical studies by identifying structural, chemical, and morphological changes in the electrodes and lithium-polysulfide's behavior during charge and discharge processes. This review also details the advantages of several in situ/operando / operando characterization techniques to study LiSBs and the electrochemical cells most suited and commonly used in the literature for each analysis presented here. It adds light to the discussion of how electrochemical impedance spectroscopy (EIS) can be used jointly with the advanced techniques discussed in this work. Here, 18 different in situ/operando techniques are summarized using the recent advanced studies in LiSBs characterization. This review presents state-of-the-art characterizations to guide researchers interested in using new in situ/operando tools for characterizing LiSBs. (AU)
