28. Bimetallic CuSbSe2: A Potential Anode Material for Sodium and Lithium‐Ion Batteries with High‐Rate Capability and Long‐Term Stability.

Abstract

Bimetallic transition metal chalcogenides (TMCs) materials have emerged as attractive anodes for lithium‐ion batteries (LIBs) and sodium‐ion batteries (SIBs) because of the high intrinsic electronic conductivity, rich redox sites and unique reaction mechanism. In this work, we report the synthesis and electrochemical properties of a novel bimetallic TMCs material CuSbSe2. The as‐prepared anode delivers a high reversible capacity of 545.6 mA h g−1 for SIBs and 592.6 mA h g−1 for LIBs at a current density of 0.2 A g−1, and an excellent rate capability of 425.9 mA h g−1 at 20 A g−1 for SIBs and 226.0 mA h g−1 at 10 A g−1 for LIBs without any common‐used surface modification or carbonaceous compositing. In addition, ex situ X‐ray diffraction (XRD) and High‐resolution transmission electron microscopy (HRTEM) reveal a combined conversion‐alloying reaction mechanism of LIBs and NIBs. Our findings suggest bimetallic CuSbSe2 could be a potential anode material for both SIBs and LIBs. [ABSTRACT FROM AUTHOR]

Abstract

The instability and low activity of WO3 is the hot-topic for photoelectrochemical (PEC) water splitting, which is decreased by a sluggish interfacial kinetics and incomplete water oxidation. Aiming at such issues, we designed a ternary WO3/RGO/Ni:FeOOH photoanode, which exhibits 2.05 times larger photocurrent (1.32 mA cm−2) than the WO3 NFs in 0.5 M Na2SO4 electrolyte solution, accompanied with 83 mV cathodic shift of onset potential. These results demonstrates PEC response can occurs only in Ni:FeOOH but not FeOOH. Therefore, Ni:FeOOH acting as bi-functional modifier, can not only increase light absorption but also promote charge transfer process by forming p-n heterojunction with the WO3 NFs. Besides, RGO forming a continuously conducting network can further improve charge separation process. Owing to their synergistic effects, the Faradaic efficiency and stability are both improved compared to its counterparts and the bare WO3 NFs. This work may inspire the PEC application in other co-catalyst decorated systems.

Abstract

The determining method of the weights of multiple attributes decision making needs to be improved. Firstly, three entropy measures are deduced through a similarity measure of intuitionistic fuzzy sets. Most of the entropy measures are not able to fully describe the uncertainty of things. So the weight determining results which based on the entropy, becomes somewhat inaccurate. The method of improving the effective information is proposed to determine the attribute weights in order to improve the accuracy of weights determining. Ultimately the ideal multiple attributes decision making analysis results are determined by adjustment weights with the parameter.

Abstract

The aim of this study was to solve the problems of mixed multiattribute group decision, which have the interval-valued, linguistic and interval-valued intuitionistic fuzzy number. As a solution to this problem, we propose a decision-making method that the decision maker weight was unknown, however, the attribute weight was known as well as the score function with transformation parameters. Firstly, conversion formula was used to make the mixed evaluation information unified transformed to the interval-valued intuitionistic fuzzy number. Furthermore, the decision maker and attribute weight were determined by the interval-valued intuitionistic fuzzy numbers distance and expectation values. Under the instruction of intuitionistic fuzzy weighted averaging operator, decision maker weight and attribute weight, we aggregated the individual decision making matrix and scheme different attribute successively. Additionally, we also made the dynamic scheduling analysis by the score function with transformation parameter. Finally, this method feasibility was testified by the example solving.

43. Effects of Structure and Magnetism on the Electrochemistry of the Layered Li1+x(Ni0.5Mn0.5)1–xO2Cathode Material

Author

Bian, Xiaofei, Zhang, Rongyu, and Yang, Xu

Abstract

We have synthesized a series of Li1+x(Ni0.5Mn0.5)1–xO2(LNMO) materials to study the influence of excess lithium ions on the structure and electrochemical behaviors of nickel–manganese-based layered compounds. The increasing content of Li+ions in the transition-metal (TM) layer leads to the departure of the follower-like clusters to Ni-rich and Mn-rich clusters. The Ni2+ions in the Li layer couple with adjacent transition-metal ions via strong 180° exchange interactions and moderate the local structure, which leads to magnetic clusters with finite size. Electrochemical performance shows that appropriate Ni2+ions could improve the cycle stability without decreasing the rate capability. Among them, Li1.1Ni0.45Mn0.45O2shows a rate capability of 76 mAh g–1at 1000 mA g–1and a lifespan of 300 cycles at 200 mA g–1. This work shows that structure moderation has an essential impact on its electrochemical performance. Besides this, the crystal and magnetic combined methods we use could offer a better way of studying cathode materials.
