摘要 ：
Zinc-air batteries (ZABs) are regarded as attractive devices for electrochemical energy storage and conversion due to their outstanding electrochemical performance, low price, and high safety. However, it remains a chal-lenge to design a stable and efficient bifunctional oxygen catalyst that can accelerate the reaction kinetics and improve the performance of ZABs. Herein, a phosphorus-doped transition metal selenide/carbon com-posite catalyst derived from metal-organic frameworks (P-CoSe2/C@CC) is constructed by a self-supporting carbon cloth structure through a simple solvothermal process with subsequent selenization and phosphati-zation. The P-CoSe2/C@CC exhibits a low overpotential of 303.1 mV at 10 mA cm-2 toward the oxygen evo-lution reaction and an obvious reduction peak for the oxygen reduction reaction. The abovementioned electrochemical performances for the P-CoSe2/C@CC are attributed to the specific architecture, the super-hydrophilic surface, and the P-doping effect. Remarkably, the homemade zinc-air battery based on our P-CoSe2/C@CC catalyst shows an expected peak power density of 124.4 mW cm-2 along with excellent cycling stability, confirming its great potential application in ZABs for advanced bifunctional electrocatalysis.(c) 2022 Elsevier Inc.

摘要 ：
Transition metal phosphides with a satisfying theoretical electrochemical characteristics are the promising environmentally friendly energy storage materials for high-performance electrochemical capacitors. The possession of high specific surface area, numerous active sites and stable structure is helpful for the electrochemical energy storage process. In this study, porous hierarchical Ni2P nanosheet arrays combined with Cu3P layers on copper foam (Ni2P/C@Cu3P-CF) is fabricated via hydrothermal-reduction/carbonization-phosphorization process using the 2D Ni-based metal organic framework nanosheets as the precursor. Benefit from this rational design and super-hydrophilic property, the Ni2P/C@Cu3P-CF electrode possess a satisfying capacity of 1105.0 mC cm(-2) at a current density of 5 mA cm(-2) and good rate performance (61.5% capacity retention at a high current density of 50 mA cm(-2)). In addition, asymmetrical all-solid-state electrochemical capacitors assembled with our Ni2P/C@Cu3P-CF electrode can deliver a high areal energy density of 1.6 mWh cm(-2 )at a power density of 0.16 mW cm(-2). Moreover, this electrochemical capacitors display the robust cycling stability with a 91.2% capacity retention after 5000 cycles at a rate of 10 mA cm(-2). These results demonstrate a great potential for the Ni2P/C@Cu3P-CF electrode in the commercial application of the advanced aqueous electrochemical energy storage device.

摘要 ：
Electrochromic energy storage devices (EESDs) integrate energy storage and electrochromism into one smart device that can realize the visualization of the energy level by the naked eyes, which has attracted extensive attention in recent years. It is critical to explore suitable electrode materials for achieving both high electrochromic and electrochemical performance. Herein, we propose an aqueous aluminum-ion electrochromic energy storage device (AIEESD) by assembling the polyaniline (PANI) electrochromic cathode, Al metal frame anode and AlCl3 electrolyte, which yields an open-circuit voltage of similar to 1.22 V and a fast self-bleaching behavior without any energy input. Additionally, the developed device exhibits outstanding electrochromic energy storage performances with discharging capacity of 68.1 mAh m(-2), excellent rate capability, large optical modulation (Delta T = 55% at 630 nm) and high coloration efficiency (93.62 cm(2) C-1 at 630 nm). Moreover, the prototype device can reversibly switch between the multicolor (transparent, light yellow, green and dark blue) when the voltage changes from 0.4 to 2.5 V, which means the energy status can be monitored by the obvious color transition. These results show that the AIEESD in this work has great application prospects for smart windows and energy storage displays.

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 ：
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 ：
Metal-organic framework (MOF) is a promising electrochromic material due to its high specific surface area and tunable pore size, which can benefit the fast transportation of ion/charge. Here, a simple solvothermal deposition method for fabrication of Ni-MOF 74 electrochromic films on ITO is developed. It is found that the reaction temperature has played an important role in the morphology and electrochromic performance of as-prepared Ni-MOF 74 film. The film prepared at the optimized temperature exhibits the best electrochromic performance with a rapid switching speed (the coloration/bleaching time = 24.5/23.5 s). In addition, the optimized film displays a high optical contrast of 44.4% at 550 nm and can be stably switched for 650 cycles with < 21.5% contrast attenuation. The electrochromism of Ni-MOF 74 can be attributed to the oxidized and reduced states of 2,5-dihydroxyterephthalic acid ligands. This simple method can be broaden to fabricate other metal-based MOF films for electrochromic applications.

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 ：
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 ：
Functional separators have played important roles in improving the electrochemical performance of lithium-sulfur (Li-S) batteries by addressing the key issues of both the sulfur cathode and lithium anode. Compared with other materials that are used for separator functionalization, two-dimensional (2D) materials with atomic layer thickness and infinite lateral dimensions feature several advantages of ultra-thin laminate structure, remarkable physical properties and tunable surface chemistry, which show potential applications in separator functionalization towards addressing the issues of both the shuttle effect and formation of Li dendrites in Li-S batteries. In this review, the unique advantages of 2D materials for separator functionalization in Li-S batteries and their common construction methods are introduced. Then, recent progress and advances in the construction of 2D materials functional separators are summarized in detail towards inhibiting the shuttle effect of polysulfides and suppressing Li dendrite growth in Li-S batteries. Finally, some opportunities and challenges of 2D materials for constructing high-performance functional separators are proposed. We anticipate that this review will provide new insights into separator functionalization for developing advanced Li-S batteries.

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.
