The stability of the lithium-metal/solid electrolyte interface remains a critical challenge in the development of all-solid-state lithium-metal batteries (ASSLMBs), as it directly influences their cycling performance, rate capability, and safety. Here, a thin, flexible, and lithium-stable sulfide electrolyte membrane is presented with high ionic conductivity (3.25 × 10 −3 S cm −1 ) and low electronic conductivity (1.45 × 10 −9 S cm −1 ) at room temperature, prepared with an AlCl 3 coating in a low-cost wet process. The in situ formation of a lithiophilic Li-Al alloy and a lithiophobic LiCl layer at the interface creates a stable dual-layer structure, effectively suppressing Li-dendrite growth and enhancing Li-transport across the interface. Symmetric Li/Li cells with this coated membrane exhibit exceptional cycling stability, operating for over 10000 h at 0.5 mA cm −2 . ASSLMBs assembled with a LiNi 0.8 Co 0.1 Mn 0.1 O 2 cathode and a metallic lithium anode exhibit excellent cycling performance, highlighting the potential of this coating strategy to stabilize the Li/solid electrolyte interface and expedite the commercialization of ASSLBs.

The equilibrium potentials of Me(III)/Me (Me = Dy, U) couples and the double Me–Ga, Me–Cd alloys vs. Cl − /Cl 2 reference electrode were measured at the temperature range 673–973 K in molten LiCl–KCl–CsCl eutectic by open-circuit potentiometry. The apparent standard potential and the base thermodynamic properties of alloys were determined. Separation factor for Dy/U couple was calculated on gallium and cadmium electrodes. In addition, it was found that the application of gallium electrodes has a significant advantage over cadmium electrodes in the process of electrochemical separation of uranium and dysprosium.

Highly efficient strategies for the transformation of amorphous carbon into graphite with high graphitization and crystallinity features have been significantly pursued in recent years; however, critical issues, including high processing temperature, insufficient graphitization, introduction of catalyst impurities, complicated post-purification procedures, and generation of greenhouse gas, still remain in traditional approaches. For significantly addressing these challenges, herein, a highly efficient catalyst-free, eco-friendly and low-temperature electrochemical transformation strategy was proposed for the preparation of highly graphitized porous graphite nanoflakes. Using inert SnO2 as an anode in CaCl2-LiCl molten salts, the graphitization transformation of amorphous carbon materials could be realized at 700 °C, approaching the record in high-efficiency converting amorphous carbon to graphite; moreover, systematical analysis was performed to understand the electrochemical transformation of amorphous carbon into highly graphitized graphite nanoflakes. For extending their valuable applications, the as-prepared graphite nanoflakes were further utilized as cathodes in aluminum-ion batteries, which exhibited significantly promising energy storage performance; moreover, an initial discharge capacity of 63.6 mA h g−1 at a current density of 200 mA g−1 was achieved, which eventually became 55.5 mA h g−1 with a coulombic efficiency of 95.4% after 1000 cycles; thus, these cathodes exhibited stable long-term cycling performance. The combination of low-temperature electrochemical transformation and the subsequent high-performance applications of these nanoflakes in energy storage indicates that the proposed strategy is highly efficient for the transformation and utilization of abundant amorphous carbon resources for the realization of high value-added applications.

Hydrogels served as core materials for wearable sensors in recent years, yet their practical application was constrained by water-loss-induced instability, suboptimal mechanical properties, and insufficient functionality in complex scenarios. To overcome these challenges, this study innovatively engineered a Janus fiber scaffold-based composite hydrogel biomimetic skin with a triple humidity-responsive mechanism, achieving substantial breakthroughs in performance optimization and multifunctional integration. HSBS leveraged triple humidity response mechanisms: chitosan-gelatin buffering, Janus scaffolds' unidirectional conduction, and LiCl deliquescence, achieving high hygroscopic sensitivity across 30–90 % RH. Concurrently, the HSBS exhibited wide temperature adaptability from −20 °C to 50 °C, exceptional strain-sensing stability, and mechanical durability, with a water retention rate of 76 % at room temperature and a tensile strength of 3.09 MPa. It could also precisely detect variations in skin temperature and humidity, as well as fluctuations in physiological signals. Endowed with a triple humidity-responsive mechanism as its core advantage, this novel biomimetic skin was poised to significantly expand the application frontier of wearable sensors in domains such as healthcare monitoring and sports science.

Hygroscopic composites based on hygroscopic salts and hydrogels are promising for atmospheric water harvesting (AWH), but their relatively low water production and possible salt leakage hinder real applications. Here, we report highly hygroscopic and leakage-free composites from loading LiCl into emulsion-templated sodium alginate and poly(vinyl alcohol) hydrogels with macroporous structures and interpenetrating polymer networks. The resulting composites exhibited an enhanced moisture uptake (up to 3.4 g g–1) and leakage-free behavior even at an extremely high relative humidity (RH) of 90%. Moreover, the composites showed accelerated adsorption, with high adsorption (0.803 g g–1 water at 25 °C and 90% RH within 1 h) and desorption due to the emulsion-templated, highly interconnected macropores. The hygroscopic composites obtained 1.12 g g–1 water per adsorption–desorption collection cycle and showed high reusability, without obvious deterioration in adsorption, desorption, and collection after 10 cycles. With the presence of carbon nanotubes, solar-driven AWH could be realized, without the requirement of additional energy. The highly hygroscopic and leakage-free composites with enhanced and accelerated adsorption and desorption are excellent candidates for efficient AWH.

Hydrogels have aroused increasing attention as flexible and wearable electronic devices due to their unique properties and multifunctionalities. Herein, a novel dual network ionic conductive poly (vinyl alcohol)/poly (γ-glutamic acid)/lithium chloride (LiCl) hydrogel with 25 wt% LiCl (PVA/γ-PGA/LiCl 0.25 ) exhibited high transparency (91.12 %), excellent anti-freezing (−80 °C), good water retention (maintain 88 % of the initial water content after 7 days at 25 °C, 44 % RH), high conductivity (11.29 ± 0.13 S/m), good flexibility (491.71 ± 17.47 %), self-healing (∼100 %, 4 h) and self-regeneration abilities were successfully developed. Meanwhile, the conformal adhesion between the PVA/γ-PGA/LiCl 0.25 hydrogel-based strain sensor and skin due to the formed hydrogen bonds, which was conductive to the generate accurate, stable, and recyclable electrical signals with excellent sensitivity (GF = 5.61). In view of these merits, the PVA/γ-PGA/LiCl 0.25 hydrogel-based sensors not only precisely captured human motions with high strain, but also succeeded in sensitively detecting slight movements of face and throat. Notably, the assembled triboelectric nanogenerators (TENGs) tactile sensors and capacitive pen by using PVA/γ-PGA/LiCl 0.25 hydrogels has provided the possibility for human-computer interaction. These applications indicated that the developed PVA/PGA/LiCl 0.25 hydrogel have great potential in the fields of wearable electronics for human motion detection, self-powered devices and human-computer interaction.

Based on the high safety and low costs, molten salt batteries (Na-S battery, liquid metal battery, ZEBRA battery, etc.) have received more and more attention as large-scale electrical storage technology. However, the high operating temperature of molten salt batteries is still one of the roadblocks that impeded their practical application. Here we present the novel Ni-graphite molten salt battery based on outstanding electrochemical reversibility of the Ni/NiCl 2 redox and intercalation/de-intercalation chemistry of chloroaluminate anions in graphite. By using the low-cost, quaternary inorganic molten salt AlCl 3 /KCl/NaCl/LiCl as electrolyte, the as-designed Ni-graphite battery possesses low operating temperature of 95 °C, and average voltage about 1.7 V. The Ni-graphite battery delivers stable specific capacity of 174 mAh/g at 500 mA/g after 120 cycles, with the capacity retention rate of 98%. In addition, the Ni-graphite battery also shows low material costs about 113.6 $/kWh and high electrode energy density of 289 Wh/kg. This work develops an advanced molten salt battery with low operating temperature and high energy density, as well as provides an alternative means of developing future large-scale power storage equipment based on molten salt batteries.

The biodegradable biomass adsorbent (cellulose- g -PSS) was synthesized in LiCl/ N, N -dimethyl acetamide by the free-radical grafting polymerization reaction between sodium styrene sulfonate (SSS) and cellulose. Systematic optimization was conducted on many reaction parameters, including reaction time, monomer dosage, and reaction temperature. The grafting yield of cellulose- g -PSS was 50.16%. The chemical structures, physical, and chemical characteristics of cellulose- g -PSS were characterized by FTIR, SEM, PZC, 1 H NMR, XRD, TGA and XPS. An assessment was conducted to determine the sorption of Ce (III) on cellulose- g -PSS by changing the contact time, adsorbent dosage, pH, initial Ce (III) concentration, and NaCl concentration. The process of adsorption rapidly reached a state of equilibrium within a time frame of 25 min and was well explained using pseudo-second-order kinetic and Langmuir isotherm model. The maximum adsorption capacity for Ce (III) obtained from the Langmuir isotherm model was 84.80 mg·g −1 . The impact of NaCl concentration on the sorption of Ce (III) and XPS analysis showed that Ce (III) ions were adsorbed onto cellulose- g -PSS through ion-exchange mechanism. As a whole, cellulose- g -PSS exhibited great potential in rare earth wastewater treatment.

To study the application perspectives of binary Ga–Al alloy electrodes in pyroprocessing, the utilization of Ga–Al alloy electrode for the separation of U from Ce was studied in this work. Specifically, the reduction behaviors of U (III) on Ga, Al and Ga–Al alloy electrodes was first explored in LiCl–KCl eutectic at 773 K. The cathode peak potential of U (III) at the Ga–Al alloy electrode was 0.44 V (vs. Li/Li 3 Bi), and less affected by the Ga/Al ratio. Moreover, potentiostatic electrolysis at 0.55 V (vs. Li/Li 3 Bi) was conducted on the Ga–Al alloy electrode for 4 h to separate U from Ce. X-ray diffraction (XRD) analysis indicated the co-existence of Al 3 U and Ga 3 U with an identical crystal structure in the deposits. Scanning electron microscopy coupled with energy dispersive spectroscopy (SEM-EDS) illustrated a good diffusion of U metal in Ga–Al alloy electrodes. Inductive coupled plasma optical emission spectrometry (ICP-OES) determinations exhibited an excellent separation performance of the Ga–Al alloy electrode.

The main purpose of this paper is to study the extraction and separation of key fragment elements based on the electrolytic refining process of spent fuel dry reprocessing. Firstly, the electrochemical mechanisms of Er(III) and Yb(III) in LiCl-KCl molten salts were investigated on W and In film electrodes with applied cyclic voltammetry (CV), square wave voltammetry (SWV) and open circuit potential (OCP) at 773 K. The results indicated that the reduction behaviour of In(III) and Yb(III) ions were a two-step transfer process and Er(III) ions was a one-step transfer process. Then, the kinetic parameters in electrochemical processes were calculated on an In electrode with different temperatures. The OCP approach was used to determine the equilibrium potential of Er(III)/Er(0) in the temperature range of 773 K∼848 K, and thermodynamic parameters of the In 3 Er alloy were provided. Based on electrochemical behaviour results, the electrochemical extraction of Er(III) and Yb(III) from LiCl-KCl-ErCl 3 molten salts and LiCl-KCl-YbCl 3 molten salts at liquid In electrodes was performed by constant potential and constant current electrolysis, respectively. The electrolysis products were determined by X-ray diffraction (XRD), scanning electron microscopy and energy dispersive spectrometry (SEM-EDS), the primary intermetallic compounds generated in the alloys were In 3 Er and In 3 Yb. The average extraction rates for Er(III) and Yb(III) were 94.70% and 96.54%, respectively, according to inductively coupled plasma atomic emission spectroscopy (ICP-AES) analysis. Er(III) and Yb(III) were selectively extracted and separated from LiCl-KCl-ErCl 3 -YbCl 3 molten salts by potentiostatic control on the basis of the previously studied Lns (Er and Yb) extraction on In electrodes. The separation rate of Er(III) and Yb(III) by electrochemical selective deposition was 94.21%.

Due to the limitation of mechanical properties , the applications of traditional polymer hydrogels are seriously hindered in many fields. In this study, a series of hydrogels with controllable mechanical properties were successfully prepared by immersing the thermo-initiated poly (acrylic acid-co-stearyl methacrylate) hydrogels into LiCl, NaCl and KCl aqueous solution. The structural changes and properties of the gel before and after soaking were explored carefully by XRD , IR and Raman, etc. It was found that except for forming coordination interactions with the carboxyl group of acrylic acid , these salts can also promote the formation of hydrophobic associations consisted of long alkyl chains, which significantly improves the mechanical properties of the gel. The tensile strength and fracture energy of the KCl aqueous solution treated hydrogels could reach to 2.1 MPa and 19 MJ/m 3 , respectively, which are much higher than those of original hydrogels. Furthermore, the prepared hydrogels also have pressure sensitive conductivity, which could be used to detect body movements.

Solid-state lithium metal batteries (SSLMBs) with high energy density and superior safety have been recognized as next-generation energy storage systems and have attracted a lot of attention. Garnet-type oxide solid-state electrolytes, especially Li6.4La3Zr1.4Ta0.6O12 (LLZTO), with high ionic conductivity, low activation energy and superior stability with Li, are among the most promising solid-state electrolyte materials. However, high interfacial resistance, uneven lithium deposition and lithium dendrite growth between Li/LLZTO interfaces have hindered the industrialization of SSLMBs. In this work, a novel mortise–tenon-like hybrid ionic/electronic conductive interface (Li/LZFC@LLZTO) is constructed, which is composed of LiF, LiCl, and a Li–Zn alloy through an in situ transformation reaction. As expected, the interfacial impedance of Li|LZFC@LLZTO|Li is significantly reduced from 128 Ω cm2 to 2.7 Ω cm2, the critical current density increases from 0.3 mA cm−2 to 2.1 mA cm−2, and a prominent cycling performance of 6600 h at 0.2 mA cm−2 or 900 h at 0.4 mA cm−2 is achieved. Consequently, both the Li|LZFC@LLZTO|LiFePO4 and Li|LZFC@LLZTO|LiNi0.8Co0.1Mn0.1O2 full cells exhibit excellent rate performance. Furthermore, Li|LZFC@LLZTO|LiFePO4 can maintain a high discharge specific capacity close to 140 mA h g−1 at 0.2C after 150 cycles of stable cycling. This work lays the foundation for developing garnet-based SSLMBs with high critical current density, low interfacial impedance and long-term cycling performance.
