Despite impressive merits of complementary charge‐storage mechanisms for aqueous Zn‐ion hybrid micro‐supercapacitors (ZHMSCs), it remains a challenge to solve dendrite and parasitic reactions issues of Zn anodes. Herein, a kinetics‐boosted strategy of Zn2+ transport and desolvation of hydrated Zn2+ is proposed by engineering zwitterionic P(AM‐co‐SBMA) hydrogel electrolyte (PASHE) for highly reversible Zn plating/stripping. Mechanically robust and chemically anchored PASHE features zwitterionic groups for constructing ion migration channels and immobilizing water molecules, which accelerates Zn2+ migration for an ultrahigh transfer number (0.84) and alleviates water‐related parasitic reactions. Theoretical calculations combined with experimental results reveal that sulfobetaine sulfonate anions endow PASHE with improved desolvation kinetics and the ability to coordinate Zn2+ flux and electric field distributions at the electrolyte–electrode interface. Thus, Zn anodes exhibit excellent electrochemical performance involving high average coulombic efficiency of 99.4% in Zn|PASHE|Cu cell as well as high cumulative capacity of 2000 mAh cm−2 (20 mA cm−2, 1 mAh cm−2) and depth of discharge of 80.9% (20 mA cm−2, 10 mAh cm−2) in Zn|PASHE|Zn cells. Furthermore, ZHMSCs based on PASHE deliver excellent flexibility and cyclability for energy‐storage applications. This work provides useful insights on hydrogel electrolyte engineering for developing high‐performance Zn anodes and derived energy‐storage devices.

“…not plastic crystals) that could be an additional advantage for electrolyte applications. Those zwitterionic additives have been used to promote Li + dissociation in polymer and gel polymer electrolytes, [19][20][21] where they are believed to facilitate the dissociation of Li ions from the polymer backbone and enhance the Li ion conductivity and Li + ion transference number (the fraction of charge carried by the Li + ). [22][23][24][25][26][27][28] Furthermore, it was reported that ZI addition can promote the amorphous phase and reduce the polymer crystallinity, also resulting in increasing Li ion mobility.…”

Stretchable ionic hydrogels with superior all‐round properties that can detect multimodal sensations with high discriminability to decouple multiple stimuli and high robustness against external disturbances are highly required for artificial electronic skin applications. However, some of the critical material parameters exhibit intrinsic tradeoffs with each other for most ionic hydrogels. Here, we demonstrate a microphase‐separated hydrogel design by combining three strategies: (1) the use of a low crosslinker/monomer ratio to obtain highly entangled polymer chains as the first network; (2) the introduction of zwitterions into the first network; (3) the synthesis of an ultrasoft polyelectrolyte as the second network. This approach creates an all‐round elastic ionic hydrogel with a skin‐like low Young's modulus (< 60 kPa), large stretchability (> 900%), high resilience (> 95%), low hysteresis (< 5%), unique strain‐stiffening behavior, excellent fatigue tolerance, high ionic conductivity (> 2.0 S/m), and anti‐freezing capability, which were not achieved with previous ionic hydrogels. These comprehensive properties allow the ionic hydrogel to operate as a stretchable multimodal sensor that can detect and decouple multiple stimuli (temperature, pressure, and proximity) with both high discriminability and sensitivity. It also shows strong sensing robustness against strains and temperature perturbations. The ionic hydrogel sensor exhibits great potential for intelligent electronic skin applications such as reliable health monitoring and accurate object identification.This article is protected by copyright.
