Abstract
Overcoming the sharp decline in ionic conductivity under harsh conditions requires the development of robust ion conductors. In this study, we present a synergistic molecular design strategy that enables energy storage devices to operate stably at low temperatures. Ion mobility was substantially improved by introducing fluorinated side chains to facilitate ion dissociation, together with tuning polymer chain length to enhance segmental motion. As a result, the resulting ion conductor showed high ionic conductivity with minimal temperature sensitivity. When integrated into micro-supercapacitors, it delivered dependable electrochemical performance even under low-temperature conditions. Overall, this molecular design approach offers a promising route toward next-generation energy storage systems suited for extreme environments.
