To reduce postharvest mechanical damage, an in-situ fruit packaging solution integrating both force cushioning and real-time sensing functions is proposed. This was achieved using the synergistic effects of ion cross-linking and the Hofmeister effect to create ZnSO 4 cross-linked double-network hydrogels directly on the fruit surface. The results show that the hydrogels exhibited superior compressive strength, deformability, and Young’s modulus. With increasing concentrations of the ZnSO 4 solution, the compressive property, Young’s modulus, and cross-linking density of the hydrogels increased, while their energy dissipation rate decreased. The hydrogels cross-linked with a 0.3 M ZnSO 4 solution was the optimal one, achieving an energy dissipation rate of 35.2 %, while their compressive strength was 3.5 times that of the uncross-linked hydrogels, along with 3.9 times higher ionic conductivity and 75.9 % lower resistance. The optimal hydrogels could output electrical signals in response to strain at different rates and proportions and exhibited stable sensing over 100 compression cycles. Furthermore, the performance of the optimal hydrogels was evaluated using ripe and fragile kiwifruit. The cushioning test results show that the hydrogels could reduce vibration, compression and dropping damage, therefore effectively protecting the fruit. Besides, the hydrogels could quantitatively detect the compression force acting on fruit surfaces by outputting electrical signals in real-time. Additionally, the hydrogels achieved 96.8 % biodegradation within 6 h and had good biocompatibility. Overall, the present study proposed an idea of fabricating an in-situ fruit packaging with both cushioning and real-time sensing functions to reduce mechanical damage and facilitate inspection for fruit during postharvest transportation.

ZnSO 4 post-impregnation enhances both the mechanical and conductive performance of the hydrogel. • The hydrogel delivers 509% tensile strain, 34.9 MPa compressive strength, and 4.67 S·m −1 conductivity. • High sensitivity (2.75 kPa −1 , GF = 2.05) hydrogel sensor enables real-time motion monitoring. • The sensor achieves a high sensitivity (TCR = 2.52% °C −1 ) for real-time body temperature monitoring. • Dual-mode sensing hydrogel promises advances in wearable electronics and smart healthcare. Achieving simultaneous enhancement of mechanical and electrical properties is the key to realizing high-performance conductive nacre-inspired hydrogels. Here a nacre-inspired conductive hydrogel strengthened by ZnSO 4 post-impregnation is reported, in which MXene nanosheets act as bricks embedded in a Hydroxypropyl methylcellulose (HPMC)/Poly(acrylic acid) (PAA) mortar. Zn 2+ ions form coordination bonds at the brick-mortar interface, while SO 4 2− ions promote chain entanglement in the mortar phase via the Hofmeister effect, synergistically enhancing the mechanical properties of the hydrogel. Concurrently, ZnSO 4 introduces additional ionic conduction pathways, which further improves the hydrogel's charge transport capability. This ZnSO 4 post-impregnation strategy leads to a holistic enhancement of the hydrogel's performance. The ZnSO 4 post-impregnated hydrogel exhibits a compressive strength of 34.90 MPa, a conductivity of 4.67 S·m −1 , and a tensile strain of 509%, which are superior to most existing conductive nacre-inspired materials. Furthermore, the well-dispersed MXene nanosheets introduce their intrinsic thermosensitivity into the hydrogel. When assembled into flexible sensors, the hydrogel enables dual-mode monitoring of both human motions (from large-range to subtle movements) and real-time body temperature. This work presents an ionic post-impregnation strategy to design high-performance nacre-inspired hydrogels for wearable sensing applications.

In recent years, the metal ion hybrid micro-supercapacitor (MSC) comprised of the battery-type Faradaic cathode based electrode and capacitor-type anode based electrode, can realize both high power and energy density, which becomes one of the most hottest areas of energy device. Herein, we demonstrated a zinc-ion hybrid micro-supercapacitor (ZIHMSC) by designing a Ti 3 C 2 T x MXene based electrode as capacitor-type anode and vanadium pentoxide (V 2 O 5 ) based electrode as battery-type cathode. In addition, the polyacrylamide (PAM) hydrogel where ZnSO 4 dissolved was chosen as the electrolyte, which effectively avoids the security risks, unlike other hybrid MSC based on the organic electrolytes. Meanwhile, the flexible ZIHMSC also exhibits well electrochemical properties, displaying a remarkable capacitance (129 mF cm −2 under 0.34 mA cm −2 ), high energy density (48.9 μWh cm −2 at 673 μW cm −2 ) and well-cycle stability (retaining ~ 77% capacitance after 10,000 cycles). This work supports a prospective routine for constructing the new-generation flexible micro-energy storage systems.

The poor reversibility and stability of Zn anodes greatly restrict the practical application of aqueous Zn-ion batteries (AZIBs), resulting from the uncontrollable dendrite growth and H 2 O-induced side reactions during cycling. Electrolyte additive modification is considered one of the most effective and simplest methods for solving the aforementioned problems. Herein, the pyridine derivatives (PD) including 2,4-dihydroxypyridine (2,4-DHP), 2,3-dihydroxypyridine (2,3-DHP), and 2-hydroxypyrdine (2-DHP), were employed as novel electrolyte additives in ZnSO 4 electrolyte. Both density functional theory calculation and experimental findings demonstrated that the incorporation of PD additives into the electrolyte effectively modulates the solvation structure of hydrated Zn ions, thereby suppressing side reactions in AZIBs. Additionally, the adsorption of PD molecules on the zinc anode surface contributed to uniform Zn deposition and dendrite growth inhibition. Consequently, a 2,4-DHP-modified Zn/Zn symmetrical cell achieved an extremely long cyclic stability up to 5650 h at 1 mA cm –2 . Furthermore, the Zn/NH 4 V 4 O 10 full cell with 2,4-DHP-containing electrolyte exhibited an outstanding initial capacity of 204 mAh g –1 , with a notable capacity retention of 79% after 1000 cycles at 5 A g –1 . Hence, this study expands the selection of electrolyte additives for AZIBs, and the working mechanism of PD additives provides new insights for electrolyte modification enabling highly reversible zinc anode.

Rechargeable aqueous zinc-ion batteries (ZIBs) are promising wearable electronic power sources. However, solid-state electrolytes with high ionic conductivities and long-term stabilities are still challenging to fabricate for high-performance ZIBs. Herein, locust bean gum (LBG) was used as a natural bio-polymer to prepare a free-standing quasi-solid-state ZnSO4/MnSO4 electrolyte. The as-obtained LBG electrolyte showed high ionic conductivity reaching 33.57 mS cm−1 at room temperature. This value is so far the highest among the reported quasi-solid-state electrolytes. Besides, the as-obtained LBG electrolyte displayed excellent long-term stability toward a Zn anode. The application of the optimized LBG electrolyte in Zn–MnO2 batteries achieved a high specific capacity reaching up to 339.4 mA h g−1 at 0.15 A g−1, a superior rate performance of 143.3 mA h g−1 at 6 A g−1, an excellent capacity retention of 100% over 3300 cycles and 93% over 4000 cycles combined with a wide working temperature range (0–40 °C) and good mechanical flexibility (capacity retention of 80.74% after 1000 bending cycles at a bending angle of 90°). In sum, the proposed ZIBs-based LBG electrolyte with high electrochemical performance looks promising for the future development of bio-compatible and environmentally friendly solid-state energy storage devices.

Aqueous zinc-ion batteries (AZIBs) have attracted significant attention owing to their inherent security, low cost, abundant zinc (Zn) resources and high energy density. Nevertheless, the growth of zinc dendrites and side reactions on the surface of Zn anodes during repeatedly plating/stripping shorten the cycle life of AZIBs. Herein, a simple organic molecule with abundant polar functional groups, 2,2,2-trifluoroether formate (TF), has been proposed as a high-efficient additive in the ZnSO 4 electrolyte to suppress the growth of Zn dendrites and side reaction during cycling. It is found that TF molecules can infiltrate the solvated sheath layer of the hydrated Zn 2+ to reduce the number of highly chemically active H 2 O molecules owing to their strong binding energy with Zn 2+ . Simultaneously, TF molecules can preferentially adsorb onto the Zn surface, guiding the uniform deposition of Zn 2+ along the crystalline surface of Zn(0 0 2). This dual action significantly inhibits the formation of Zn dendrites and side reactions, thus greatly extending the cycling life of the batteries. Accordingly, the Zn//Cu asymmetric cell with 2 % TF exhibits stable cycling for more than 3,800 cycles, achieving an excellent average Columbic efficiency (CE) of 99.81 % at 2 mA cm −2 /1 mAh cm −2 . Meanwhile, the Zn||Zn symmetric cell with 2 % TF demonstrates a superlong cycle life exceeding 3,800 h and 2,400 h at 2 mA cm −2 /1 mAh cm −2 and 5 mA cm −2 /2.5 mAh cm −2 , respectively. Simultaneously, the Zn//VO 2 full cell with 2 % TF possesses high initial capacity (276.8 mAh/g) and capacity retention (72.5 %) at 5 A/g after 500 cycles. This investigation provides new insights into stabilizing Zn metal anodes for AZIBs through the co-regulation of Zn 2+ solvated structure and surface crystallography.

The zinc anode mainly faces technical problems such as short circuits caused by the growth of dendrite, low coulomb efficiency, and a short cycle life caused by side reactions, which impedes the rapid development of aqueous zinc-ion batteries (AZIBs). Herein, a common ionic liquid, 1,1-Spirobipyrrolidinium tetrafluoroborate ([SBP]BF4), is selected as a new additive for pure ZnSO4electrolyte. It is found that this additive could regulate the solvation sheath of hydrated Zn2+ions, promote the ionic mobility of Zn2+, homogenize the flux of Zn2+, avoid side reactions between the electrolyte and electrode, and inhibit the production of zinc dendrites by facilitating the establishment of an inorganic solid electrolyte interphase layer. With the 1% [SBP]BF4-modified electrolyte, the Zn||Zn symmetric cell delivers an extended plating/stripping cycling life of 2000 h at 1 mA cm−2, which is much higher than that of the cell without additives (330 h). As a proof of concept, the Zn‖V2O5battery using the [SBP]BF4additive shows excellent cycling stability, maintaining its specific capacity at 97 mAh g−1after 2000 cycles at 5 A g−1, which is much greater than the 46 mAh g−1capacity of the non-additive battery. This study offers zinc anode stabilization through high-efficiency electrolyte engineering.
