Preparation and Characterization of Li2S6 Electrolyte
Sulfur and Li2S at a molar ratio of 5:1 were dissolved in a mixture of 1,2-dimethoxyethane (DME)/1,3-dioxolane (DOL) solution containing 1.0 mol L−1 LiTFSI and 2 wt% LiNO3 to prepare Li2S6 electrolyte. Symmetric cells were assembled by applying CP/Cu-2 as the working and counter electrodes, and the Li2S6 electrolyte usage was 20 μL. CV tests were conducted between –1 and 1 V at the scan rates of 50 and 0.5 mV s−1. CV profiles of the symmetric cells were collected on a Metrohm Autolab G204 Electrochemical Workstation.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
