With the proposal of carbon peaking and carbon neutrality goals, clean energy storage is attracting more and more attentions. In view of the lack of lithium resource in our earth, sodium-ion batteries are considered as the emerging and promising next-generation energy storage devices. Appropriate high-performance anode materials play a vital role in the development of sodium-ion batteries. Here, a core-shell hollow Ni-Co-P nanopolyhedron interconnected by oxygen defect TiO 2 (Ni-Co-P@TiO 2- x ) is reported, which is synthesized by ion etching-hydrolysis and subsequent phosphatization/hydrogenation treatment using ZIF-67 as template and hybrid carbon source. The achieved Ni-Co-P@TiO 2- x material has several distinct advantages including hollow core-shell structure, flexible conductive carbon matrix, stable electroactive coating layer, and efficient pseudocapacitive behavior, resulting in high reversible capacities, remarkable rate capability and excellent cycle stability. The synergetic battery-capacitor characteristic of Ni-Co-P@TiO 2- x material makes it become a promising anode for sodium-ion batteries.

We aimed to recover Ni and Co from the leaching sulfate solution of nickel-based superalloy scraps (NSL) and to synthesize NiCo 2 O 4 through oxalate co-precipitation-calcination technique. The structural and compositional analyses of the resultant products were characterized utilizing x-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). Furthermore, the effects of nickel-cobalt molar ratio and calcination temperature on the oxygen evolution reaction (OER) performance were investigated. The results indicated that under optimal conditions of 0.7 M C 2 O 4 2− addition, 25°C, and 4 h reaction time, the precipitation efficiencies for Co 2+ and Ni 2+ were 99.19% and 95.79%, respectively. The precipitate derived from adjusting the Ni/Co molar ratio in NSL manifested as a solid solution of nickel-cobalt oxalate (Ni x Co 3-x (C 2 O 4 ) 3 ). As the molar ratio decreased, the precipitates gradually transformed from a nickel oxalate structure with Ni sites replaced by Co to a cobalt oxalate structure with Ni replacing Co sites. The pure phase structure NiCo 2 O 4 , synthesized with a Ni/Co molar ratio of 1/2 and calcined at 450°C for 2 h, exhibited an overpotential of 430 mV at a current density of 10 mA·cm −2 in 0.1 M KOH, a Tafel slope of 93.69 mV·dec −1 , and a C dl of 242.75 mF·cm −2 . Upon exceeding 450°C during calcination, the gradual expulsion of heteroatoms from the matrix resulted in structural destruction. Consequently, the electrocatalytic activity of the sample decreased because of the gradual removal of surface oxygen vacancy concentration and Co 3+ /Co 3+ + Co 2+ . The methodology employed in this study not only efficiently recovers Ni 2+ and Co 2+ from the NSL but also prepares electrocatalysts with superior performance for the oxygen evolution reaction.

Hierarchical core–shell structure is benefit for the fast diffusion and bulk storage of electron/ion while metal nitrides (MN) exhibit metal-like behavior with excellent conductivity. Herein, nickel cobalt glycerate solid spheres (NiCo-G) and nickel cobalt glycerate yolk–shell structure (NiCo-GYS) were successfully synthesized via solvothermal reactions, accompanied by annealing using urea as a cheap and convenient nitrogen source to obtain metal nitride/bimetallic oxide core–shell heterostructure (NiCoNO). Excellent specific capacitance of 1878 F g −1 at 1 A g −1 is displayed by the prepared NiCoNO. Amazingly, the distinct core–shell construction guarantees high stability during the charge/discharge operation. NiCoNO maintains an 83.9% specific capacitance after 5000 cycles at 10 A g −1 . Furthermore, the all-solid-state hybrid supercapacitor was assembled using NiCoNO cathode and active carbon (AC) anode components. The device has an excellent capacitive retention rate of 81.1% after 5000 cycles at 10 A g −1 and a good energy density of 64.2 Wh kg −1 at a power density of 900 Wh kg −1 . A light-emitting diode (LED) bulb can be lighted for 3 min, indicating the promising practical application prospect of the supercapacitor.

Fe-Ni-Co alloy films demonstrate outstanding soft magnetic properties and are widely used as magnetic materials. The ultrasonic-assisted electrodeposition method is highly regarded for its merits in improving alloy film performance. In this study, Fe-Ni-Co alloy film with a uniform composition was fabricated through ultrasonic-assisted electrodeposition. The effects of the electrodeposition parameters on the composition and microstructure of the Fe-Ni-Co alloy films were studied. The results revealed that lower initial electrolyte pH, temperature ( T ), and ultrasonic power ( P ) were conducive to the increase of the iron content of the alloy films. As the ultrasonic power increased, the crystal structure of the Fe-Co-Ni films changed from bcc (FeCo) to fcc (NiFe), and the mean grain size decreased. When the electrodeposited condition was pH = 2, T = 50°C, and P = 45 W, the Fe 58.36 Ni 36.01 Co 5.63 alloy film showed a better corrosion resistance than 304 stainless steels. When the electrodeposited condition was pH = 2, T = 50°C, and P = 90 W, the Fe 53.84 Ni 41.66 Co 4.48 alloy film exhibited good magnetic properties, and the saturation magnetic induction and coercivity were 1.75 T and 85 A/m, respectively, which was much better than Fe-Co-Ni alloy films (Ni: about 40 wt.%) prepared by traditional electrodeposition.

The synthesis of primary amines from renewable biobased carbonyl compounds via reductive amination has received much attention. Modifying the surface structure of a heterogeneous catalyst may offer prospects to address selectivity maneuvering in this complex amination process. In this work, a metal–organic framework (MOF)-derived carbon-coated strategy was adopted to prepare the Ni@C catalysts with different thicknesses of carbon shells. This type of Ni catalyst achieved 98% yield of (5-(aminomethyl)furan-2-yl)methanol (AMF) at 100 °C under 2 bar of H2 from reductive amination of 5-hydroxymethylfurfural (HMF, an important cellulose-derived platform molecule) with NH3·H2O. In comparison, a Ni-NiO catalyst obtained by reducing NiO with H2 would mainly overhydrogenate AMF to (5-(aminomethyl)tetrahydrofuran-2-yl)methanol (THAMF, 52% in yield) as a byproduct. The modification of the electronic structure of Ni0 active sites with a carbon shell was elucidated, demonstrating electron-rich Ni0 sites for H2 activation. Moreover, different HMF adsorption modes on Ni-NiO and Ni@C surfaces were illustrated, significantly affecting the product distribution. Subsequently, distinctive NH3·H2O activation processes were proposed for both Ni catalysts to understand selective conversion of the Schiff base (i.e., the critical reaction intermediate). The developed Ni@C catalyst with suitable carbon thickness, abundant Ni0 centers, and defective carbon species showed high AMF yield under mild reaction conditions, facile separation–regeneration, and satisfying reusability. In addition, this Ni catalyst can also provide a relatively good substrate scope toward bioamine synthesis via reductive amination.

Solar-driven hydrogen production is significant for achieving carbon neutrality but is limited by unsatisfactory surface catalytic reaction kinetics. Layer regulation can impact carrier transmission or catalytic behavior, but the specific effects on the oxygen or hydrogen evolution reaction (OER or HER) remain unclear, and atomic layer level modulation for maxing HER is challenging. Here the distinct roles of modulated Zn–S or In–S surface layers in ZnIn 2 S 4 (ZIS) for the OER and HER, respectively, are disentangled. Moreover, the extensive characterizations and computational results demonstrate that stressful environments enable individual modulation and introduce Ni into the surface In–S layer rather than the easily alterable Zn–S layer, creating deeper hybridized electronic states of Ni 3 d –S 3 p , optimizing H * adsorption/desorption, and maximizing surface catalytic benefits for the HER. Consequently, the optimized ZIS exhibited a photocatalytic hydrogen production rate of up to 18.19 mmol g −1 h −1 , ≈32 times higher than pristine ZIS. This investigation expands the application scenarios of ultrasonic technology and inspires other precise control types, such as defects and crystal plane engineering, etc.

Exploiting bifunctional and highly efficient electrocatalysts that can facilitate the reversible formation and decomposition of discharge products is crucial for rechargeable Na-air batteries (SABs). However, restricted by scaling relations, air cathodes based on single metal systems usually exhibit inferior activity and fail to achieve a stable and long cycle life of Na-air batteries. Dual single-atom catalysts (DACs) with two metal sites can circumvent the scaling relations and endow the single-atom catalysts with superior activity. Herein, we present a hollow carbon microsphere loaded with Ni and Fe single atoms (Ni-HCMs-Fe) as a demonstration of DAC air cathodes for SABs. Notably, Na-air batteries with Ni-HCMs-Fe as an air cathode can achieve a low overpotential gap of 530 mV, a high specific capacity of 5382.9 mAh g−1, and an ultralong cycle life of over 450 cycles (1800 hours) with NaO2 as the main discharge product. Due to the different adsorption energies between oxygenated intermediates and Ni/Fe sites, the Ni-HCMs-Fe catalysts can break through the scaling relations and display optimized binding ability towards intermediates, thus boosting the reversible formation and decomposition of NaO2 in SABs. This work pioneers the use of DACs in SABs, paving the way for their practical applications.

Design of the photosensitive electrode material provides an effective strategy to improve the capacity and stability of supercapacitors. In this study, the photothermal-driven cobalt–zinc-doped Ni(OH)2/g-C3N4@NF nanoflower electrode materials were prepared base on the in situ chemical etching strategy. The electrochemical performance indicated that the optimized CZNC2.18 (cobalt–zinc codoped β-Ni(OH)2@g-C3N4) electrode material with exceptional stability (103.74% capacitance retention after 5000 cycles at 20 mA/cm2) exhibited an ultrahigh capacitance of 19.10 F/cm2 at a current density of 10 mA/cm2 under illumination, compared to 12.8 F/cm2 under dark conditions, achieving a light gain of 149%. The assembled asymmetric photothermal-assisted supercapacitor device delivers energy densities of 3.55 mWh/cm2 (1.23 mWh/cm2) at corresponding power densities of 8.39 mW/cm2 (37.03 mW/cm2) under illumination, surpassing performance metrics observed under dark conditions. The synergistic effects of photogenerated carriers (holes oxidizing Ni(OH)2 to NiOOH and electrons enhancing conductivity), Zn/Co codoping-induced conductivity improvement, and photothermal-assisted ion transport collectively enable CZNC2.18 exceptional photoelectrochemical performance, establishing a paradigm for light-responsive energy storage material design.

The LiNi 0.8 Co 0.1 Mn 0.1 O 2 (Ni-rich NCM) cathode materials suffer from electrochemical performance degradation upon cycling due to detrimental cathode interface reactions and irreversible surface phase transition when operating at a high voltage (≥4.5 V). Herein, a traditional carbonate electrolyte with lithium difluoro(oxalato)borate (LiDFOB) and tris(trimethylsilyl)phosphate (TMSP) as dual additives that can preferentially oxidize and decompose to form a stable F, B and Si-rich cathode-electrolyte interphase (CEI) that effectively inhibits continual electrolyte decomposition, transition metal dissolves, surface phase transition and gas generation. In addition, TMSP also removes trace H 2 O/HF in the electrolyte to increase the electrolyte stability. Owing to the synergistic effect of LiDFOB and TMSP, the Li/LiNi 0.8 Co 0.1 Mn 0.1 O 2 half cells exhibit the capacity retention 76.3% after 500 cycles at a super high voltage of 4.7 V, the graphite/LiNi 0.8 Co 0.1 Mn 0.1 O 2 full cells exhibit high capacity retention of 82.8% after 500 cycles at 4.5 V, and Li/LiNi 0.8 Co 0.1 Mn 0.1 O 2 pouch cells exhibit high capacity retention 94% after 200 cycles at 4.5 V. This work is expected to provide an effective electrolyte optimizing strategy compatible with high energy density lithium-ion battery manufacturing systems.

The precarious interfacial chemistry between the electrode and electrolyte is the determining step that restricts the long cycle life of Ni-rich-based Li-metal batteries. Here we show that the robust cathode electrolyte interphase (CEI) and solid electrolyte interphase (SEI) layers can be engineered by tuning the spatial linking structure of dipentacyclic anhydride (DPA) additives. Specifically, an inorganic-rich CEI/SEI layer induced by CBDA (a DPA featuring a quaternary ring spatial linking structure) exhibits superior Li + interfacial kinetics and an ultra-stable cycle performance, outperforming the other systems. As a result, the NCM811ǁLi cells containing CBDA show excellent long-term performances, even under high voltage, high load, and high charge-discharge current density, respectively. The coin-cell using a low-loading cathode exhibits 129 mAh g- 1 discharged capacity for over 200 cycles at a 6 C rate. Moreover, The high-loading cathode retains 80 % capacity after 312 cycles at 1.0 C. Furthermore, the NCM811ǁLi pouch cell demonstrated a capacity retention rate of 99.8 % after 50 cycles. Prolonged stable cycling for 900 cycles (93 % capacity retention) in an NCM811ǁGraphite pouch cell is enabled by CBDA. The DPA-based additives in this work offer a highly promising and feasible route to achieving a long-term and high-capacity lithium battery featuring a Ni-rich cathode.

The conventional sintered W-Ni-Fe alloy encounters challenges in achieving both high strength and plasticity simultaneously, primarily due to its inadequate organizational compatibility. To address this issue, we developed a novel approach combining in situ freeze-drying and straightforward liquid-phase sintering techniques to effectively control the microstructure of 93W-4.9Ni-2.1Fe alloys. The corresponding W-Ni-Fe alloy in this work simultaneously takes into account ultrafine W grains (28.3 µm), low W-W connectivity (CW-W = 0.31), and suitable γ phase volume fraction (20.2%), which is currently difficult for traditional W-Ni-Fe alloys to achieve. The minute dimensions of nanopowder play a crucial role in inhibiting Ostwald ripening and facilitating W grain refinement. Additionally, the extensive surface area of nanopowder enhances capillary penetration, leading to effective homogenization of high γ phase volume. As a result, the freeze-dried W-Ni-Fe alloy simultaneously achieves high strength (1010 MPa) and high plasticity (31%), which provides a new insight for the further development of W-Ni-Fe alloy industries.

Parasitic multiscale free radical reactions of electrolytes not only deteriorate battery performance but also cause a fire hazard. Therefore, fundamentally blocking free radical reactions is a smart strategy for simultaneous improvement. Herein, a multiscale free radical annihilating agent hexachlorocyclotriphosphazene cross-linked tannic acid microsphere (HT) is unprecedentedly applied to polyethylene glycol diacrylate based in-situ constructed polymer electrolytes (PEGGPE@HT), which significantly annihilates free radicals from electrolytes at high-voltage and high temperature. The electrochemical stability of PEGGPE@HT is improved to 4.5 V (Li/Li + ). The capacity retention rate of the LiNi 0.8 Mn 0.1 Co 0.1 O 2 (NCM811)//Li cell is increased to 85.3% after 200 cycles at 1 C and that of the LiFePO 4 //Li cell is up to 96.4% after 400 cycles at 1 C by the presence of HT. Moreover, the effectiveness of this strategy has also been further validated in the NCM811//Graphite pouch full cell and high loading NCM811//ultra-thin Li cell. Furthermore, benefiting from the annihilation of phosphorus radicals generated from HT at high temperatures, the PEGGPE@HT shows good flame retardancy and endows the pouch cell with excellent fire safety. Additionally, the pouch cell also features excellent mechanical abuse resistance. This facile synthesis is compatible with the existing battery industry process, which renders great potential for PEGGPE@HT to construct competitive LIBs with high energy density and high safety in large-scale applications.
