Figure 2

Electrochemical characterization of the polymer-in-salt electrolyte. (a) The temperature dependence of ionic conductivity of the polymer-in-salt electrolyte measured in a symmetric cell with stainless-steel blocking electrodes. (b) Cyclic voltammetry and linear sweep voltammetry profiles of cells at 60°C consisting of the polymer-in-salt electrolyte, a stainless-steel working electrode, and a lithium-metal reference electrode. (c) Polarization profile of a lithium-lithium symmetric cell at 60°C with the polymer-in-salt electrolyte; inset shows the impedance spectra of the cell before and after the polarization. (d) Variation of interfacial resistance of a lithium-lithium symmetric cell at 60°C with the polymer-in-salt electrolyte as a function of time.
