Summary: This study presents a flexible, thin, and lightweight poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) nanopaper as an anion-cation regulation synergistic interlayer for aqueous zinc-iodine (Zn-I2) batteries. The PEDOT:PSS interlayer with a 3D nanofibrous network and uniformly distributed mesopores effectively suppresses polyiodide shuttling and promotes dendrite-free zinc plating/stripping at high current densities and high areal capacities. The Zn-I2 batteries demonstrate high capacity and ultralong lifespan even at high current densities. This work highlights the potential of multifunctional interlayers for innovation in Zn-I2 battery configurations by synergistic regulation of cations and anions at the electrodes/electrolyte interface.

Summary: Micro-supercapacitors (MSCs) have significant advantages and have attracted increasing attention. However, in open systems, they often need to be encapsulated to ensure stable performance. In this study, we demonstrate a high water-retaining and antifreeze micro-supercapacitor (AW-MSC) that does not require encapsulation and is adaptable to all-weather conditions. The AW-MSC uses an ion conductive hydrogel as the electrolyte and exhibits outstanding water holding capacity and freeze resistance. In harsh environments, the AW-MSC retains over 85.0% of its capacitance.

Summary: Reclaiming kinetic energy from vibrating machines holds great promise for sustainable energy harvesting technologies. This research develops a conductive hydrogel with an electro-responsive polymeric network, which can be used for lightweight, miniaturized, and integrated high-frequency electrochemical devices. The hydrogel can quickly form a localized electrolyte layer under the influence of an applied voltage, allowing for rapid charge transport with an exceedingly high local charge density. The micro-capacitor based on this gel exhibits a record-high capacitance when the frequency of energy input reaches up to 104 Hz. Additionally, a prototype battery charger that harvests energy from a running car engine is demonstrated in this study. This research presents a feasible strategy for waste energy recycling using integrated electrochemical devices, opening a new avenue for ambient energy management.
