Web11 aug. 2016 · The measured conductivity of lithiated Nafion (Li-N117) is approximately two orders of magnitude higher in DMSO than in ACN according to Doyle et al., 26 however a recent paper reported a much higher conductivity for lithiated Nafion (N1035) soaked in ACN. 27 This discrepancy motivated us to reproduce these conductivity measurements. WebPercentage of Li present in the lithiated-Nafion calculated from the ICP Procedure: 0.5 ml of the lithiated polymer solution (stock in ethanol) was dried under reduced pressure. The dried mass was digested with concentrated nitric acid + H 2 O 2 mixture and further diluted for ICP measurements.
