Abstract ：
Electrocatalytic C-N coupling reaction is regarded as a promising strategy for achieving clean and sustainable urea production by coreducing CO2 and nitrogen species, thus contributing to carbon neutrality and the artificial nitrogen cycle. However, restricted by the sluggish adsorption of reactants, competitive side reactions, and multistep reaction pathways, the electrochemical urea production suffers from a low urea yield rate and low selectivity so far. In order to comprehensively improve urea synthesis performance, it is crucial to develop highly efficient catalysts for electrochemical C-N coupling. In this article, the catalyst-designing strategies, C-N coupling mechanisms, and fundamental research methods are reviewed. For the coreduction of CO2 and different nitrogen species, several prevailing reaction mechanisms are discussed. With the aim of establishing the standard research system, the fundamentals of electrocatalytic urea synthesis research are introduced. The most important catalyst-designing strategies for boosting the electrocatalytic urea production are discussed, including heteroatom doping, vacancy engineering, crystal facet regulation, atom-scale modulation, alloying and heterostructure construction. Finally, the challenges and perspectives are proposed for future industrial applications of electrochemical urea production by C-N coupling. The rational design of efficient heterogeneous electrocatalysts is crucial but still very challenging for sustainable urea production at ambient conditions by coreducing CO2 and nitrogen species. In this review article, design strategies for C-N coupling electrocatalysts are emphasized-for the in-depth understanding of the structure-activity relationship and the establishment of a systematic research framework -toward this emerging field. image

Abstract ：
Solid polymer electrolytes (SPEs) for lithium metal batteries have garnered considerable interests owing to their low cost, flexibility, lightweight, and favorable interfacial compatibility with battery electrodes. Their soft mechanical nature compared to solid inorganic electrolytes give them a large advantage to be used in low pressure solid-state lithium metal batteries, which can avoid the cost and weight of the pressure cages. However, the application of SPEs is hindered by their relatively low ionic conductivity. In addressing this limitation, enormous efforts are devoted to the experimental investigation and theoretical calculations/simulation of new polymer classes. Recently, metal-organic frameworks (MOFs) have been shown to be effective in enhancing ion transport in SPEs. However, the mechanisms in enhancing Li+ conductivity have rarely been systematically and comprehensively analyzed. Therefore, this review provides an in-depth summary of the mechanisms of MOF-enhanced Li+ transport in MOF-based solid polymer electrolytes (MSPEs) in terms of polymer, MOF, MOF/polymer interface, and solid electrolyte interface aspects, respectively. Moreover, the understanding of Li+ conduction mechanisms through employing advanced characterization tools, theoretical calculations, and simulations are also reviewed in this review. Finally, the main challenges in developing MSPEs are deeply analyzed and the corresponding future research directions are also proposed.

Abstract ：
Water electrolysis for hydrogen production holds great promise as an energy conversion technology. The electrolysis process contains two necessary electrocatalytic reactions, one is the hydrogen evolution reaction (HER) at the cathode, and the other is the oxygen evolution reaction (OER) at the anode. In general, the kinetics of OER is much slower than that of HER, dominating the overall of performance electrolysis. As identified, the slow kinetics of catalytic OER is mainly resulted from multiple electron transfer steps, and the catalysts often undergo compositional, structural, and electronic changes during operation, leading to complicated dynamic reaction mechanisms which have not been fully understood. Obviously, this challenge presents formidable obstacles to the development of highly efficient OER electrocatalysts. To address the issue, it is crucial to unravel the origins of intrinsic OER activity and stability and elucidate the catalytic mechanisms across diverse catalyst materials. In this context, in-situ/operando characterization techniques would play a pivotal role in understanding the catalytic reaction mechanisms by enabling real-time monitoring of catalyst structures under operational conditions. These techniques can facilitate the identification of active sites for OER and provide essential insights into the types and quantities of key reaction intermediates. This comprehensive review explores various catalyst design and synthesis strategies aimed at enhancing the intrinsic OER activity and stability of catalysts and examines the application of advanced in-situ/operando techniques for probing catalyst mechanisms during the OER process. Furthermore, the imperative need for developing innovative in-situ/operando techniques, theoretical artificial intelligence and machine learning and conducting theoretical research to better understand catalyst structural evolution under conditions closely resembling practical OER working states is also deeply discussed. Those efforts should be able to lay the foundation for the improved fabrication of practical OER catalysts.

Abstract ：
Solid oxide fuel cells (SOFCs) are one of the most efficient energy conversion devices. However, the sluggish oxygen reduction reaction (ORR) kinetics at low temperatures significantly challenge the performance and commercialization of SOFCs. Introducing negative expansion coefficient materials has been recognized as an effective approach to enhancing the ORR catalytic properties, but a clear understanding of this enhanced electrochemical performance is still lacking. In this work, the composite cathode of PrBa0.5Sr0.5Co1.5Fe0.5O5+δ (PBSCF) with different amounts of negative-thermal-expansion material Sm0.85Zn0.15MnO3 (SZM) is prepared, and in-depth analysis the effect of SZM on the catalytic activity of cathodic ORR is systematically investigated. Simultaneously, the mechanistic studies verify that the enhanced ORR activity might be attributed to the constructed compression strain during sintering, which significantly improves the adsorption, dissociation, and oxygen ion exchange process of the PBSCF cathode. © 2024 Elsevier B.V.

Abstract ：
Carbon defects coupled with heteroatoms can asymmetrically rearrange the local electronic distribution and coordination environment of active sites, improving the catalytic selectivity and activity of a two-electron oxygen reduction reaction (2eORR). In this study, an asymmetry defective carbon (asy-DC) structure using wolfberry as the carbon source is employed to adjust the charge distribution of active sites with different degrees of asymmetry caused by N→S coordination bonds. The asymmetric region exhibits a considerable positive correlation between the asymmetry degree and adsorption energy for OOH*, presenting a volcano relation between the asymmetry degree and catalytic activity. The optimised asy-DC catalyst exhibits high selectivity and reliable activity after 12 h of stability testing. This study can provide a new reference into the origin of ORR activity and selectivity. © 2024 Elsevier B.V.

Abstract ：
Rechargeable all-solid-state sodium batteries (ASS-SBs), including all-solid-state sodium-ion batteries and all-solid-state sodium-metal batteries, are considered highly advanced electrochemical energy storage technologies. This is owing to their potentially high safety and energy density and the high abundance of sodium resources. However, these materials are limited by the properties of their solid-state electrolytes (SSEs) and various SSE/Na interfacial challenges. In recent years, extensive research has focused on understanding the interfacial behavior and strategies to overcome the challenges in developing ASS-SBs. In this prospective, the sodium-ion conduction mechanisms in different SSEs and the interfacial failure mechanisms of their corresponding batteries are comprehensively reviewed in terms of chemical/electrochemical stability, interfacial contacts, sodium dendrite growth, and thermal stability. Based on mechanistic analysis, representative interfacial engineering strategies for the interface between SSEs and Na anodes are summarized. Advanced techniques, including in situ/ex situ instrumental and electrochemical measurements and analysis for interface characterization, are also introduced. Furthermore, advanced computer-assisted methods, including artificial intelligence and machine learning (which can complement experimental systems), are discussed. The purpose of this review is to outline the solid-state electrolyte and electrolyte/anode interface challenges, and the potential research directions for overcoming these challenges. This would enable target-oriented research for the development of solid-state electrochemical energy storage devices.

Abstract ：
The state-of-charge (SOC) and state-of-health (SOH) of lithium-ion batteries affect their operating performance and safety. The coupled SOC and SOH are difficult to estimate adaptively in multi-temperatures and aging. This paper proposes a novel transformer-embedded lithium-ion battery model for joint estimation of state-of-charge and state-of-health. The battery model is formulated across temperatures and aging, which provides accurate feedback for unscented Kalman filter-based SOC estimation and aging information. The open-circuit voltages (OCVs) are corrected globally by the temporal convolutional network with accurate OCVs in time-sliding windows. Arrhenius equation is combined with estimated SOH for temperature-aging migration. A novel transformer model is introduced, which integrates multiscale attention with the transformer’s encoder to incorporate SOC-voltage differential derived from battery model. This model simultaneously extracts local aging information from various sequences and aging channels using a self-attention and depth-separate convolution. By leveraging multi-head attention, the model establishes information dependency relationships across different aging levels, enabling rapid and precise SOH estimation. Specifically, the root mean square error for SOC and SOH under conditions of 15 °C dynamic stress test and 25 °C constant current cycling was less than 0.9% and 0.8%, respectively. Notably, the proposed method exhibits excellent adaptability to varying temperature and aging conditions, accurately estimating SOC and SOH.

Abstract ：
The state of health (SOH) and remaining useful life (RUL) of lithium-ion batteries are crucial for health management and diagnosis. However, most data-driven estimation methods heavily rely on scarce labeled data, while traditional transfer learning faces challenges in handling domain shifts across various battery types. This paper proposes an enhanced vision-transformer integrating with semi-supervised transfer learning for SOH and RUL estimation of lithium-ion batteries. A depth-wise separable convolutional vision-transformer is developed to extract local aging details with depth-wise convolutions and establishes global dependencies between aging information using multi-head attention. Maximum mean discrepancy is employed to initially reduce the distribution difference between the source and target domains, providing a superior starting point for fine-tuning the target domain model. Subsequently, the abundant aging data of the same type as the target battery are labeled through semi-supervised learning, compensating for the source model's limitations in capturing target battery aging characteristics. Consistency regularization incorporates the cross-entropy between predictions with and without adversarial perturbations into the gradient backpropagation of the overall model. In particular, across the experimental groups 13–15 for different types of batteries, the root mean square error of SOH estimation was less than 0.66 %, and the mean relative error of RUL estimation was 3.86 %. Leveraging extensive unlabeled aging data, the proposed method could achieve accurate estimation of SOH and RUL. © 2024 The Authors

Abstract ：
Heterostructure engineering is considered a crucial strategy to modulate the intrinsic charge transfer behavior of materials, enhance catalytic activity, and optimize sulfur electrochemical processes. However, parsing the role of heterogeneous interface-structure - property relationships in heterostructures is still a key scientific issue to realize the efficient catalytic conversion of polysulfides. Based on this, molybdenum carbide (Mo 2 C) was successfully partial reduced to molybdenum metal (Mo) via a thermal reduction at high-temperature and the typical Mo-Mo 2 C-based Mott-Schottky heterostructures were simultaneously constructed, which realized the modulation of the electronic structure of Mo 2 C and optimized the conversion process of lithium polysulfides (LPS). Compared with single molybdenum carbide, the modulated molybdenum carbide acts as an electron donor with stronger Mo -S bonding strength as well as higher polysulfide adsorption energy, faster Li 2 S conversion kinetics, and greatly facilitates the adsorption -> catalysis process of LPS. As a result, yolk-shell Mo-Mo 2 C heterostructure (C@Mo-Mo 2 C) exhibits excellent cycling performance as a sulfur host, with a discharge specific capacity of 488.41 mAh g -1 for C@Mo-Mo 2 C/S at 4 C and present an excellent high -rate cyclic performance accompanied by capacity decay rate of 0.08 % per cycle after 400 cycles at 2 C. Heterostructure-acting Mo 2 C electron distribution modulation engineering may contributes to the understanding of the structure -interface -property interaction law in heterostructures and further enables the efficient modulation of the chemical behavior of sulfur.

Abstract ：
Lithium-sulfur batteries (LSBs) are considered next-generation energy storage and conversion solutions owing to their high theoretical specific capacity and the high abundance/low-cost of sulfur-based cathode materials. However, LSBs still encounter significant challenges, including the low conductivities of sulfur-based materials, severe volumetric expansion of sulfur during the discharge process, and the persistent “shuttle effect” of polysulfides. In recent years, a tremendous amount of research has been conducted to address the above challenges by developing coating and compositing materials and corresponding fabrication strategies for sulfur-based cathode materials. In this study, the surface coating, compositing materials, and fabrication methodologies of LSB cathodes are comprehensively reviewed in terms of advanced materials, structure/component characterization, functional mechanisms, and performance validation. Some technical challenges are analyzed in detail, and possible future research directions are proposed to overcome the challenges toward practical applications of lithium-sulfur batteries. © 2024 Wiley-VCH GmbH.
