Abstract Li‐ and Mn‐rich layered oxides exhibit high specific capacity due to the cationic anionic reaction process during high‐voltage cycling (≥4.6 V). However, they face challenges such as low initial coulombic efficiency (~70 %) poor stability. Here, we propose a combination of H 3 BO treatment temperature calcination construct shell with vacancy on surface Li 1.2 Ni 0.2 Mn 0.6 O 2 (LLNMO). The produces lattice distortion, forming an oxidized n − (0< <2) surface, accompanied by...
Li- and Mn-rich layered oxides exhibit high specific capacity due to the cationic anionic reaction process during high-voltage cycling (≥4.6 V). However, they face challenges such as low initial coulombic efficiency (~70 %) poor stability. Here, we propose a combination of H3BO3 treatment temperature calcination construct shell with vacancy on surface Li1.2Ni0.2Mn0.6O2 (LLNMO). The produces lattice distortion, forming an oxidized On- (0<n<2) surface, accompanied by electrons redistribution....
In this study, an optimum tempering temperature after a thermo-mechanical control process (TMCP) was proposed to improve the hydrogen-induced ductility loss of high-vanadium X80 pipeline steel. The results showed that with increasing from 450 650 °C, size and quantity granular bainite decreased but spacing deformed lath ferrite fraction massive increased. number fine vanadium carbides increased as well. However, 700 microstructure T700 steel completely converted grain became larger....
In this research, super gravity field was introduced to investigate the macrosegregation behavior of solute Cu in Al-Cu alloys systematically. And mechanism also explored by well-designed experiments. When were solidified field, generated and increases along direction field. The becomes severer with increasing coefficient content. Al-4.5wt%Cu alloy G = 800, copper content at bottom position up 8.48 wt% that decreases only 2.58 wt%, resulting positive segregation negative top sample....
The effects of three different kinds cooling processes on the properties microstructure for hydrogen‐induced cracking (HIC) resistance and hydrogen atom diffusion X80 pipeline steel have been investigated in laboratory. results show that Steel F after furnace contains coarse polygonal ferrite (PF), quasi‐polygonal (QF), a small amount granular bainite (GB). A air finer QF GB. W water quenching treatment large GB, lath (LB), martensite (M) ferrite. In addition, permeation test atoms diffuse...
The role of vanadium content in hydrogen diffusion behaviour X80 pipeline steel has been investigated. results show that the coefficient decreases from 1.54 × 10−6 cm2 s−1 1# with 0.03 wt-% to 9.97 10−7 3# 0.14 due increase irreversible and reversible traps. With content, more carbides precipitate tested steels. length (or number) low angle grain boundaries special because refinement, making number traps increase. dynamic condition diffusible largest is weakest. To weaken hydrogen-induced...
A series of single crystals Li(Mn1-x,Nix)PO4 (x = 0.00, 0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.08, 0.10, 0.15, 0.20, and 0.50) have been grown to large sizes up 5 mm in diameter 120 length using the floating zone method for first time. The comprehensive characterizations as-grown were performed before further physical property measurements. composition was determined by energy-dispersive X-ray spectroscopy. crystal structures characterized powder diffraction with a GSAS fitting structural...
Comprehensive ab initio electronic structure calculations were performed for a newly developed deep-ultraviolet (DUV) non-linear optical (NLO) crystal Ca2B10O14F6 (CBOF) using the first principle method. Fifteen point defects including interstitial, vacancy, antisite, Frenkel, and Schottky of Ca, O, F, B atoms in CBOF thoroughly investigated as well their effects on absorption properties. Their formation energies equilibrium concentrations also calculated by total energy calculations. The...
