The aqueous zinc-ion battery is promising as grid scale energy storage device, but hindered by the instable electrode/electrolyte interface. Herein, we report the lean-water ionic liquid electrolyte for aqueous zinc metal batteries. The lean-water ionic liquid electrolyte creates the hydrophobic tri-layer interface assembled by first two layers of hydrophobic OTF − and EMIM + and third layer of loosely attached water, beyond the classical Gouy–Chapman–Stern theory based electrochemical double layer. By taking advantage of the hydrophobic tri-layer interface, the lean-water ionic liquid electrolyte enables a wide electrochemical working window (2.93 V) with relatively high zinc ion conductivity (17.3 mS/cm). Furthermore, the anion crowding interface facilitates the OTF − decomposition chemistry to create the mechanically graded solid electrolyte interface layer to simultaneously suppress the dendrite formation and maintain the mechanical stability. In this way, the lean-water based ionic liquid electrolyte realizes the ultralong cyclability of over 10000 cycles at 20 A/g and at practical condition of N/P ratio of 1.5, the cumulated areal capacity reach 1.8 Ah/cm 2 , which outperforms the state-of-the-art zinc metal battery performance. Our work highlights the importance of the stable electrode/electrolyte interface stability, which would be practical for building high energy grid scale zinc-ion battery.

Thermal runaway, a major battery safety issue, is triggered when the local temperature exceeds a threshold value resulting from slower heat dissipation relative to heat generation inside the cell. However, improving internal heat transfer is challenged by the low thermal conductivity of metal current collectors (CCs) and challenges in manufacturing nonmetal CC foils at large scales. Here we report a rapid temperature-responsive nonmetallic CC that can substitute benchmark Al and Cu foils to enhance battery safety. The nonmetallic CC was fabricated through a continuous thermal pressing process to afford a highly oriented Gr foil on a hundred-meter scale. This Gr foil demonstrates a high thermal conductivity of 1,400.8 W m−1K−1, about one order of magnitude higher than those of Al and Cu foils. Importantly, LiNi0.8Co0.1Mn0.1O2||graphite cells integrated with these temperature-responsive foils show faster heat dissipation, eliminating the local heat concentration and circumventing the fast exothermic aluminothermic and hydrogen-evolution reactions, which are critical factors causing the thermal failure propagation of lithium-ion battery packs.

A mesoporous TiO2−x material comprised of small, crystalline, vacancy-rich anatase nanoparticles (NPs) shows unique optical, thermal, and electronic properties. It is synthesized using polymer-derived mesoporous carbon (PDMC) as a template. The PDMC pores serve as physical barriers during the condensation and pyrolysis of a titania precursor, preventing the titania NPs from growing beyond 10 nm in size. Unlike most titania nanomaterials, during pyrolysis the NPs undergo no transition from the anatase to rutile phase and they become catalytically active reduced TiO2−x. When exposed to a slow electron beam, the NPs exhibit a charge/discharge behavior, lighting up and fading away for an average period of 15 s for an extended period of time. The NPs also show a 50 nm red-shift in their UV/Vis absorption and long-lived charge carriers (electrons and holes) at room temperature in the dark, even long after UV irradiation. The NPs as photocatalysts show a good activity for CO2 reduction. © 2020 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim

With the wide application of soft tissue fillers, implant material-induced inflammatory reactions have become a key factor affecting the therapeutic efficacy. This study developed an injectable filler with enhanced anti-inflammatory and antioxidant effects by adsorbing glycyl-L-histidyl-L-lysine copper complex (GHK-Cu) onto hydroxyapatite microspheres (HAPs), marking the first combination of HAPs and GHK-Cu to address inflammation caused by soft tissue fillers. GHK-Cu was successfully loaded onto HAPs by electrostatic adsorption. HAPs were then mixed with carboxymethyl cellulose (CMC), glycerol (GLY), and water to form GHK-Cu@CMHA gel. The study focus on the effective combination of HAPs as a carrier for sustained GHK-Cu delivery and the anti-inflammatory properties of GHK-Cu. GHK-Cu@CMHA exhibits sustained release properties for 7 days, which ensures prolonged therapeutic effects, minimizes peptide waste and reduces injection frequency, with good flowability and injectability. In the model of LPS-induced inflammation model in vivo and in vitro, GHK-Cu@CMHA gel reduced levels of inflammatory factors and Reactive oxygen species (ROS) levels decreased, while superoxide dismutase (SOD) activity was enhanced. In this process, H&E staining and Masson staining revealed significant collagen deposition. These findings further confirm that GHK-Cu@CMHA is a novel injectable soft tissue filler with good anti-inflammatory and antioxidant properties, which holds well potential for inflammation inhibition. © 2025, The Authors.

Lithium-sulfur batteries have the advantages of high theoretical energy density(2600 Wh kg-1), low-cost and environmental friendliness, which is one of the most promising secondary battery systems. However, the practical application of Li-S batteries has still been restricted by the low Coulombic efficiency and rapid capacity decay deriving from the low conductivity of sulfur cathode, large volume expansion（～80%） during discharging, and serious lithium corrosion/dendrite of anode, particularly, high dissolution of the discharge intermediate polysulfides（LiPSs） in electrolyte and shuttle effect between cathode and anode.

Self-assembly of functional units represents an important synthetic approach in the rational design of nanomaterials with precisely-controlled chemical compositions, nanostructures and desired properties, and hence finds vast applications in areas including but not limited to biomedical engineering, separation, energy storage and conversion. The functional units which can be used in self-assembly range from small molecules, metal ions, clusters, nanoparticles to large polymeric molecules. Finely tuning the functional groups of assembly units and the bonding/interactions between the units can generate versatile materials with unique structures and properties, thus leading to the desired performances for various applications. Notably, under varied external conditions, the chemical bonding, interactions between the assembly units and the structures can also be varied, which further endows these materials with responsive properties for applications in multidisciplinary areas. In recent years, I have studied a series of self-assembled nanostructured materials which are based on metal-organic coordinative compounds constructed between metal ions and organic ligands. Nanostructuring of these materials endow them with greatly enhanced properties in electrochemical energy storage. Moreover, in combination with controlled pyrolysis and understanding of the structure-property relationship, the rational design and controlled synthesis of nanocarbon composite electrode materials towards high-performance electrochemical energy storage and conversion becomes feasible. In this talk, I will present some of our recent work on the rational design of self-assembled metal-organic nanostructures and their derived nanocarbon materials for electrochemical energy storage.

One-dimensional nanomaterials can offer large surface area, facile strain relaxation upon cycling and efficient electron transport pathway to achieve high electrochemical performance. Hence, nanowires have attracted increasing interest in energy related fields. We designed the single nanowire electrochemical device for in situ probing the direct relationship between electrical transport, structure, and electrochemical properties of the single nanowire electrode to understand intrinsic reason of capacity fading. The results show that during the electrochemical reaction, conductivity of the nanowire electrode decreased, which limits the cycle life of the devices. We have developed a facile and high-yield strategy for the oriented formation of CNTs from metal-organic frameworks（MOFs）. The appropriate graphitic N doping and the confined metal nanoparticles in CNTs both increase the densities of states near the Fermi level and reduce the work function, hence efficiently enhancing its oxygen reduction activity. In addition, we demonstrated the critical role of structural HO. The results suggest that the HO-solvated Zn possesses largely reduced effective charge and thus reduced electrostatic interactions with the VO framework, effectively promoting its diffusion. We also identified the exciting electrochemical properties（including high electric conductivity, small volume change and self-preserving effect） and superior sodium storage performance of alkaline earth metal vanadates through preparing CaVO nanowires. Furthermore, a novel assembled nanoarchitecture was also presented, which consists of VO nanoparticles embedded in amorphous carbon nanotubes that are then coassembled within a reduced graphene oxide network. The naturally integrated advantages of each subunit exhibit highly stable and ultrafast sodium-ion storage. Our work presented here can inspire new thought in constructing novel one-dimensional structures and accelerate the development of energy storage applica

Hydrogels are promising candidates for flexible electronics but are often constrained by narrow pressure-sensing ranges and unstable ion migration. To overcome these limitations, we developed an ionic hydrogel sensor incorporating diode-inspired bipolar architectures (PSSNa/PDACl) and poly(vinylidene fluoride)/carbon directional microchannels (PCDMC). The optimized 5-PCNPC hydrogel exhibits a broad pressure-sensing range (2.3–100 kPa) with a sensitivity of 0.360 mV·kPa−1 (a 34.8 % enhancement) and a rectification ratio of 12.9, enabled by PCDMC-guided anisotropic ion transport and rapid stress dissipation (337 ms recovery). With excellent durability over 500 cycles and a power density of 1.17 mW·m−2, the hydrogel sensor demonstrates its potential in practical applications, including a 5 × 5 touchpad for spatial pressure mapping and real-time monitoring of respiration, swallowing, grasping and locomotion. This study underscores the potential of hydrogel-based sensors with wide-range operability for next-generation wearables and interactive systems. © 2025 Elsevier B.V.
