Flexible zinc-ion batteries (ZIBs) with high capacity and long cycle stability are essential for wearable electronic devices. Hydrogel electrolytes have been developed to provide ion-transfer channels while maintaining the integrity of ZIBs under mechanical strain. However, hydrogel matrices typically swollen aqueous salt solutions increase ionic conductivity, which can hinder intimate contact electrodes reduce properties. To address this, a single-Zn-ion-conducting electrolyte (SIHE) is by...
Dihydrogen bonding can increase intermolecular interactions and confine molecular motion to prolong the lifetime of ultralong organic phosphorescence.
Achieving environmentally friendly solvent-processed high-performance organic photovoltaic cells (OPVs) is a crucial step toward their commercialization. Currently, OPVs with competitive efficiencies rely heavily on harmful halogenated solvent additives. Herein, the green and low-cost 9-fluorenone (9-FL) employed as solid additive. By using o-xylene/9-FL system, PM6:BTP-eC9-based devices deliver power-conversion of 18.6% 17.9% via spin-coating blade-coating respectively, outperforming all...

Abstract Herein, we synthesized two donor‐acceptor (D‐A) type small organic molecules with self‐assembly properties, namely MPA‐BT‐BA and MPA‐2FBT‐BA, both containing a low acidity anchoring group, benzoic acid. After systematically investigation, it is found that, the fluorination, MPA‐2FBT‐BA demonstrates lower highest occupied molecular orbital (HOMO) energy level, higher hole mobility, hydrophobicity stronger interaction perovskite layer than that of MPA‐BT‐BA. As result, device based‐on...
Nanozymes have been extensively investigated to imitate protein enzymes in biomimetic chemistry and the identification of active site is believed be pre-requisite before one can effectively regulate their activity. Herein, ultrathin NiCo LDH nanosheets are synthesized via a fast co-precipitation at room temperature stably dispersed water without any additives surfactants or organic solvents. By tuning ratio between Ni Co nanosheets, activity tuned peroxidase-like determined by sites that...
Organic solar cells (OSCs) have great potential to completely change the development trend of entire industries and become next generation commercial cells. Compared with polymer cells, nonfullerene all‐small‐molecule organic (NF‐ASM OSCs) system has advantages easy purification, no batch effect, etc. Moreover, their power conversion efficiency (PCE) exceeds commercialization threshold 10%. Recently, diversity small‐molecule materials steady increase in PCE values suggest a bright future for...
Abstract To enhance the areal energy density of current flexible storage devices, hybrid capacitors combining advantages supercapacitors and batteries are proposed further enhanced by incorporating 3D interdigital structure design.

Abstract Rechargeable batteries are deemed as green and efficient energy storage systems have drawn great attention during past decades. Despite the commercial applications of lithium‐ion batteries, ever‐increasing demands for higher capability driven by rapid development portable/wearable electronics remain unsatisfied due to low theoretical capacity commonly used graphite anode.
