摘要 ：
Electrochemical water splitting is the most direct and popular method to obtain hydrogen. However, the high activation barrier for water splitting greatly hinders large-scale hydrogen production, inspiring the necessity of using catalysts for the hydrogen evolution reaction and oxygen evolution reaction. Materials from precious metals to earth-abundant transition metals and their composites have been widely developed, in which transition metal selenides display a more outstanding bifunctional catalytic performance. This review aims to focus on the design strategies of transition metal selenide based catalysts from modification methods, including morphological control, anion substitution and cation substitution, as well as using composite materials modified by constructing heterostructures and the synergistic effect of different components. Finally, it provides guidance for the research status, and future development directions of multifunctional electrocatalytic selenide based materials are also suggested.

摘要 ：
As one of the most promising conducting polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) has attracted significant interests in electrochemical applications such as energy storage and electrochromism. However, the intrinsic PEDOT having a dense structure usually exhibits unsatisfactory electrochemical performance such as low charge storage capacity and optical modulation behavior, which limits their applications in supercapacitors and electrochromic devices. In this case, nanoengineering provides an effective strategy to improve the electrochemical performance by optimizing the conjugated structure of PEDOT. Herein, comprehensive reviews and discussions are conducted to demonstrate the nanoengineering of PEDOT for boosting the electrochemical applications. The advantages and shortcomings of PEDOT are discussed firstly, and thus introducing the necessary of nanoengineering for optimizing the electrochemical performance. Some strategies of nanoengineering are summarized according to the classification of physical and chemical methods. Then, the latest advances and progresses are reviewed in detail concerning the applications of nanoengineered PEDOT in supercapacitors and electrochromic devices. Finally, some challenges and prospects are proposed to show the further development of nanoengineering of advanced PEDOT materials and devices. We anticipate that this review will spark new ideas for the construction of high-performance PEDOT towards developing advanced electrochemical devices.

摘要 ：
The dynamic process of ions transport in electrochromic WO3 film is usually studied by electrochemical impedance spectroscopy. However, the detailed features are hidden since the ions insertion into WO3 is a very complex process including structural deformation and phase transformations. Chronopotentiometry is an electrochemical characterization method that measures the response potential of a system under an imposed current. Compared to other dynamic characterization methods (impedance spectroscopy and CV), it allows direct access to the voltage contributions in different states of the solution-electrode system and has frequently been used to investigate kinetic effects such as adsorption and transport phenomena near electrode surface. In this study, chronopotentiometry is creatively applied to study ion transport kinetics and control ions insertion behavior in electrochromic WO3 film. The results suggest that a large ions insertion flux at the interface of WO3/electrolyte could broaden ions transport channels due to the fierce lattice expansion during Li+ ions insertion process, which further improves the ions transportation kinetics and gifts a fast switching speed of optical performance. However, the repeating ions insertion/extraction behaviors at the interface of WO3/electrolyte for the long-term cycle process can reduce the size of WO3 grains as a 'ball mill effect'. Especially, a large ions transport flux can aggravate the 'ball mill effect'. Consequently, the structure of the WO3 film becomes very dense, which is unfavorable for ions transport and electrolyte permeation. This dense structure also leads to an irreversible accumulation of Li+ ions and LixWO3 in the WO3 host structure, resulting in a decay of optical modulation ability and electrochromic activity. This work offers an efficient method to analyze ion transport kinetics in intercalation materials and a new understanding of the relationship between ion transport behavior and cyclic stability of electrochromic materials. © 2021, Science Press.

摘要 ：
Layered ternary lithium-ion batteries LiNixCoyMnzO2 (NCM) and LiNixCoyAlzO2 (NCA) have become mainstream power batteries due to their large specific capacity, low cost, and high energy density. However, these layered ternary lithium-ion batteries still have electrochemical cycling problems such as rapid capacity decline and poor thermal stability. These problems are mainly caused by (1) irreversible phase transition, (2) crack and pulverization of cathode electrode material particles, (3) dissolution of transition metal elements, (4) oxidative decomposition of electrolyte and (5) repeated growth and thickening of the SEI film on the anode electrode. In order to solve these problems, various strategies based on doping and coating of the cathode material, design of electrolyte, and anode coating have been studied to effectively stabilize the NCM/NCA cathode and achieve the purpose of improving its electrochemical cycling performance. This review briefly describes the working principle of lithium-ion batteries, the composition and structure of NCM/NCA cathode materials and the roles of transition metal elements. The capacity degradation mechanism of layered ternary lithium-ion batteries is reviewed from the perspectives of cathode, electrolyte and anode, and the research progress in the modification of cathode materials is emphatically discussed. Advances in the modification of anode materials and electrolyte design are also briefly introduced. Finally, some challenges and prospects are proposed for the future development of layered ternary lithium-ion batteries.

摘要 ：
Single-atom catalysts provide an effective approach to reduce the amount of precious metals meanwhile maintain their catalytic activity. However, the sluggish activity of the catalysts for alkaline water dissociation has hampered advances in highly efficient hydrogen production. Herein, we develop a single-atom platinum immobilized NiO/Ni heterostructure (Pt-SA-NiO/Ni) as an alkaline hydrogen evolution catalyst. It is found that Pt single atom coupled with NiO/Ni heterostructure enables the tunable binding abilities of hydroxyl ions (OH*) and hydrogen (H*), which efficiently tailors the water dissociation energy and promotes the H* conversion for accelerating alkaline hydrogen evolution reaction. A further enhancement is achieved by constructing Pt-SA-NiO/Ni nanosheets on Ag nanowires to form a hierarchical three-dimensional morphology. Consequently, the fabricated Pt-SA-NiO/Ni catalyst displays high alkaline hydrogen evolution performances with a quite high mass activity of 20.6Amg(-1) for Pt at the overpotential of 100mV, significantly outperforming the reported catalysts. While H-2 evolution from water may represent a renewable energy source, there is a strong need to improve catalytic efficiencies while maximizing materials utilization. Here, authors examine single-atom Pt on nickel-based heterostructures as highly active electrocatalysts for alkaline H-2 evolution.

摘要 ：
Metal organic frameworks (MOFs) have been considered as one of the most promising electrode materials for electrochemical capacitors due to their large specific surface area and abundant pore structure. Herein, we report a Co-MOF electrode with a vertical-standing 2D parallelogram-like nanoarray structure on a Ni foam substrate via a one-step solvothermal method. The as-prepared Co-MOF on a Ni foam electrode delivered a high area-specific capacitance of 582.0 mC cm(-2) at a current density of 2 mA cm(-2) and a good performance rate of 350.0 mC cm(-2) at 50 mA cm(-2). Moreover, an asymmetric electrochemical capacitor (AEC) device (Co-MOF on Ni foam//AC) was assembled by using the as-prepared Co-MOF on a Ni foam as the cathode and a active carbon-coated Ni foam as the anode to achieve a maximum energy density of 0.082 mW cm(-2) at a power density of 0.8 mW cm(-2), which still maintained 0.065 mW cm(-2) at a high power density of 11.94 mW cm(-2). Meanwhile, our assembled device exhibited an excellent cycling stability with a capacitance retention of nearly 100% after 1000 cycles. Therefore, this work provides a simple method to prepare MOF-based material for the application of energy storage and conversion.

摘要 ：
Developing high energy density lithium secondary batteries is pivotal for satisfying the increasing demand in advanced energy storage systems. Lithium metal batteries (LMBs) have attracted growing attention due to their high theoretical capacity, but the lithium dendrites issue severely fetter their real-world applications. It is found that reducing anion migration near lithium metal prolongs the nucleation time of dendrites, meanwhile, promoting homogeneous lithium deposition suppresses the dendritic growth. Thus, regulating ion transport in LMBs is a feasible and effective strategy for addressing the issues. Based on this, a functional separator is developed to regulate ion transport by utilizing a well-designed metal-organic frameworks (MOFs) coating to functionalize polypropylene (PP) separator. The well-defined intrinsic nanochannels in MOFs and the negatively charged gap channels both restricts the free migration of anions, contributing to a high Li+ transference number of 0.68. Meanwhile, the MOFs coating with uniform porous structure promotes homogeneous lithium deposition. Consequently, a highly-stable Li plating/stripping cycling for over 150 h is achieved. Furthermore, implementation of the separator enables LMBs with high discharge capacity, prominent rate performance and good capacity retention. This work is anticipated to aid developement of dendrite-free LMBs by utilizing advanced separators with ion transport management.

摘要 ：
In order to achieve high precision from non-contact temperature measurement, the hardware structure of a broadband correlative microwave radiometer, calibration algorithm, and temperature inversion algorithm are innovatively designed in this paper. The correlative radiometer is much more sensitive than a full power radiometer, but its accuracy is challenging to improve due to relatively large phase error. In this study, an error correction algorithm is designed, which reduces the phase error from 69.08 degrees to 4.02 degrees. Based on integral calibration on the microwave temperature measuring system with a known radiation source, the linear relationship between the output voltage and the brightness temperature of the object is obtained. Since the metal aluminum plate, antenna, and transmission line will have a non-linear influence on the receiver system, their temperature characteristics and the brightness temperature of the object are used as the inputs of the neural network to obtain a higher accuracy of inversion temperature. The temperature prediction mean square error of a back propagation (BP) neural network is 0.629 degrees C, and its maximum error is 3.351 degrees C. This paper innovatively proposed the high-precision PSO-LM-BP temperature inversion algorithm. According to the global search ability of the particle swarm optimization (PSO) algorithm, the initial weight of the network can be determined effectively, and the Levenberg-Marquardt (LM) algorithm makes use of the second derivative information, which has higher convergence accuracy and iteration efficiency. The mean square error of the PSO-LM-BP temperature inversion algorithm is 0.002 degrees C, and its maximum error is 0.209 degrees C.

摘要 ：
Catalytically active metals atomically dispersed on supports presents the ultimate atom utilization efficiency and cost-effective pathway for electrocatalyst design. Optimizing the coordination nature of metal atoms represents the advanced strategy for enhancing the catalytic activity and the selectivity of single-atom catalysts (SACs). Here, we designed a transition-metal based sulfide-Ni3S2 with abundant exposed Ni vacancies created by the interaction between chloride ions and the functional groups on the surface of Ni3S2 for the anchoring of atomically dispersed Pt (Pt-SA-Ni3S2). The theoretical calculation reveals that unique Pt-Ni3S2 support interaction increases the d orbital electron occupation at the Fermi level and leads to a shift-down of the d -band center, which energetically enhances H2O adsorption and provides the optimum H binding sites. Introducing Pt into Ni position in Ni3S2 system can efficiently enhance electronic field distribution and construct a metallic-state feature on the Pt sites by the orbital hybridization between S-3p and Pt-5d for improved reaction kinetics. Finally, the fabricated Pt-SA-Ni3S2 SAC is supported by Ag nanowires network to construct a seamless conductive three-dimensional (3D) nanostructure (Pt-SA-Ni3S2@Ag NWs), and the developed catalyst shows an extremely great mass activity of 7.6 A mg(-1) with 27-time higher than the commercial Pt/C HER catalyst.

摘要 ：
The selective transport of charge carriers has a great impact on the efficiency of electrochemical energy storage and conversion. However, pursuing membranes with high-performance ion selectivity is one of the most crucial issues for their further progress. In recent years, based on their superior intrinsically physical and chemical properties including abundant nano-sized channels, open metal sites and electrostatic interaction, metal-organic frameworks (MOFs) have shown enormous potential for the construction of membranes with ion selectivity. In this review, the design and mechanism of MOF-based membranes with ion selectivity are first discussed. Based on this, the applications of these membranes in typical electrochemical energy storage and conversion systems are summarized. Based on the recent advances, the existing challenges and the future perspectives are discussed. This review will offer new insights for understanding the ion transport in MOF-based membranes with ion selectivity towards high-performance electrochemical energy storage and conversion.
