    Enhanced Charge Transport through Ion Networks in Highly Concentrated LiSCN‐Polyethylene Carbonate Solid Polymer Electrolytes by Kajal Kumbhakar, Sourav Palchowdhury, Thuy Duong Pham, Seoeun Shin, So Yeon Chun, Joong Won Shim, Kyung‐Koo Lee, Minhaeng Cho, Kyungwon Kwak

    Published 2025-06-01
    “…However, the transition observed from subionic to superionic behavior in the Walden plot indicates the onset of segmental motion decoupled charge transport pathway. The SCN− vibrational spectrum elucidates the evolution from a Li–SCN–Li type chain‐like structure to a Li2 > SCN < Li2 type extended ion network with increasing LiSCN concentration, revealing that the ion network provides an alternative channel for Li+ ion transfer at higher concentrations, enhancing conductivity.…”
