Professor Li Zhimin's team of Materials Institute published research results in top journals in the international energy field

Recently, the research results between Professor Li Zhimin, Professor Li Zhimin of the School of Advanced Materials and Nano Science and Technology, and Guizhou Zhenhua New Materials Co., Ltd. and other researchers. The title of Batteries was published at the top journal of international energy in the international energy field Advanced Energy Materials (IF: 29.698). The work is the first unit of Xi'an University of Electronic Science and Technology. The first author is Ye Tao, a graduate student of the 2020 master of advanced materials and the School of Science and Technology, and Professor Li Zhimin and researcher at Qianxin.

High-nickel-free cobalt linixmn1-xo2 (NM, x ≥ 0.5) positive electrode material has the advantages of high discharge ratio and low cost, and has become the next-generation lithium-ion battery positive material with great development potential, but its difference has been unable to fail the performance. Solved well. In view of this, the work prepares a series of high-nickel lini0.6CO0.4-XMNXO2 (NCM, X = 0, 0.2, 0.3, 0.4) of the high nickel lini 0.6CO0.4-XMNXO2 (NCM, X = 0, 0.2, 0.3, 0.4) Poor performance factors. Studies have found that the mn content changes mainly change the transition metal layer spacing in the NCM crystal structure. The transformation of the lattice parameters caused by it is not the root cause of its multiplier performance. By understanding the origin of the structure and magnification of different MN content NCM positive material structures and multiplier performance changes, the work pointed out that the introduction of non -magnetic ions such as AL3+and MG2+as an effective Strategy.

(A) NM64, NCM613, NCM622, NCM631, and NC64 battery multiplier performance; (B) LI+ion diffusion coefficient; (C) NM64 sample SEM diagram; (D) XRD diagram; (E) XRD refined transition metal layer (SMO2) The distance between the lithium layer (ILIO2) layer; (F) AR+ion etching and 250S MN 2P XPS spectrum and MN 3S XPS spectrum; (G) Linio2, NC64, NCM631, NCM622, NCM613, and NM64 effective magnetic magnetic magnetic magnetic magnetic Mixed row of torque μEff and li/ni; (H) NC64, LNO, and NM64 a pair of li/ni ion exchange required for formation capacity

This work not only provides a new understanding of the role of MN elements in high -nickel -free NM -layered oxides orthophyllum materials, and also proposes a effective strategy to improve its difference. The development of ion battery NM positive materials provides strong theoretical support and technical reserves.

The Mechanical and Electrical Institute published the results of Yuechen Protection Research in the AMI journal

Yue Chen is an important space environmental factors that plagued the exploration of the moon. The problem of mechanical, thermal control systems and optical surface failures caused by a series of moon dust has become an important issue that needs to be solved in the process of lunar exploration. Although the traditional mechanical vibration, blowing, electric field exclusion and other active dust removal methods can significantly inhibit the gathering of materials on the surface of the material, it is difficult to widely apply due to energy consumption and structured restrictions. With the development of science and technology, the development of functional materials for the development of moon dust adsorption has become a very promising passive protection method, but at present people still lack an in -depth understanding of the mechanism of related role. Recently, Professor Wang Weidong of Xi'an University of Electronic Science and Technology, Researcher Tang Yiyu, the Central Academy of Institute of Science and Technology, and the Institute of Space Technical Physics, the Institute of Geochemistry of the Chinese Academy of Sciences, the University of Science and Technology of Macau, and the City University of Hong Kong. Of Aluminum Surface with Multi-Scale Roughness Prepared by A Composite Etching Method "was published on the well-known international journal ACS Applied Materials & Interfaces. Doctoral student Wang Xiao is the first author of this article, and the School of Electromechanical Engineering is the first unit. The paper proposes the use of a variety of wet etching methods to prepare aluminum -based surfaces with different micro -structures. The appearance and roughness of the aluminum -based surface through SEM and AFM are confirmed that the composite etching on the aluminum -based surface has been compounded on the aluminum -based surface. Construct a micro -nano -level structure. The adhesion of different surfaces and single-month dust particles was measured through the homemade moonchen particle probe CLDS-TIP. Based on fractal theory, Van Dehuari was calculated from different surfaces and particles. The calculation value was consistent with the experimental value. From the perspective of micro mechanics, the effectiveness of the micro -structure reduced the effectiveness of the particle adhesion. CLDS-TIP probe adhesion test results (A) Original aluminum tablets; (b) chemical carving aluminum tablets surface; (C) electrochemical carving aluminum tablets surface; (d) composite etching aluminum tablet surface; e) The schematic diagram of the adhesion force test;

In addition, a dust -proof evaluation device based on centrifugal methods is designed, which calculates the surface dust coverage based on digital image processing methods. Statistics show that the surface (2.19%) of the compound etching (2.19%) has a lower surface coverage than the original surface (9.11%). The statistical results of the macro dustproof experiment established a connection with the measurement of micro -mechanical measurement, analyzed the effects of different load capacity and the influence of the dumping angle on the statistical results, and verified the excellent abrasion resistance of the aluminum -based surface through the friction experiment. From the aspects of micro mechanics and macro statistics, this work verifies the effectiveness of multi -scale micro -nano -structures to reduce the adhesion of Yuechen particles. It is expected to provide effective experiments and theoretical methods for subsequent related research.
