Fig. 3: The ionic conductivity of polymer electrolyte.

The ionic conductivity (σ) versus temperature (T) of PEO-LiTFSI and PEO-LiTFSI-AlOC, the error bars correspond to the standard deviation from the average \(\log (\sigma )\) obtained by measuring at least five individual experiments at each temperature point. The specific fitting equation of Arrhenius plots and the calculation of activation energy can be found in Methods.
