Figure 3: Electrochemical performance of using MS as an independent separator. (a) Voltage profiles of a symmetrical cell directly using MS as a separator (Li‖MS-Li), compared to a conventional cell with a PP separator (Li‖Li). Inset shows the structure of Li‖MS-Li. (b) Rate performances of two cells at currents from 0.5 to 10 mA cm-2. Inset shows the evolution of overpotential of Li‖MS-Li depending on the current.
