Coupling of high ion transport efficiency in hydrogel electrolytes and interfacial fusion for performance enhancement in all-solid-state paper-based self-powered electrochromic devices with low-temperature tolerance

Coupling the Hofmeister effect-enhanced hydrogel electrolyte with gravure-printed micro-rough paper electrode is a facile way to construct a low-temperature-tolerant all-solid-state paper-based self-powered ECD.
