Lithium‐Assisted Proton Conduction at 150 °C in a Microporous Triazine‐Phenol Polymer

Abstract

A practically nonconducting triazine‐phenol polymer with high surface‐hydrophobicity is transformed into a proton conducting electrolyte by tunable Li+ loading. The high hydration tendency of the Li+ enables the retention of residual waters assisting conductivities as high as 1.63 × 10−3 S cm−1 even at 150 ºC. The crucial role of residual water is rationalized by comparing the conductivities in D2O and H2O.
