Figure presents 5 interesting outliers: PPM, PCL, CSSAX1, SiMEME and SiMEPR. The first three polymers have high transference number. However, PPM also has a high fraction of charged carriers, meaning it solvates Li well. However, Figure shows that PPM has the highest ionic conductivity activation energy. Looking at Figure (e) we confirm the results from Fang et. al, that Li in PPM matrix is coordinated by multiple polymer chains. The high solubility of LiTFSI and the existence of multiple chains in the coordination environment points to the fact that PPM is able to solvate Li ions between multiple chains, which is in contrast to the majority of high conductivity polymers in this study. As noted in the work by Fang et. al, having a multi-chain coordination of Li enables it to be able to hop from chain to chain more efficiently. As a disadvantage PPM has significantly lower CRU dynamics (Figure (b)) compared to the other high conductivity polymers, which leads to having an overall lower ionic conductivity.
