This data and graph were contributed by Chuanchuan Li in Shandong University.
This diagram shows the reaction process of Li2S8→Li2S. The experimental data was prepared by electrochemical method, which is plotted as light red fill-area. It is partially covered by two dark red basal beds constructed from an exponential fit. And the uncovered area is the capacity of the Li2S8→Li2S reaction process, which is what we need.
To know how to plot this graph, please download the above project file (in the Zip file). There is a Note window to show the detail steps for plotting this graph.
