The cathode materials work as the host framework for both Li+ diffusion and electron transport in Li-ion batteries. property is always research focus, while less studied. Herein, we propose a unique strategy to elevate rate performance through promoting surface electric conductivity. Specifically, disordered rock-salt phase was coherently constructed at of LiCoO2 , conductivity by over one magnitude. It increased effective voltage (Veff ) imposed bulk, thus driving more extraction/insertion...
Abstract As one of the most promising cathodes for Li‐ion batteries, Li‐rich layered oxides suffer from low Coulombic efficiency, severe capacity fading, and voltage decay, which are related to aggregated Li@Mn 6 superstructure units. Herein, a Co‐free oxide Li[Li 1/4 Mn 1/2 Ni 1/6 Al 1/12 ]O 2 through substitution Co in , is designed. Combining average structural refinement with detailed local structural/chemical analysis, it found that introduced ions occupy sites units, further induces...
Understanding the mechanism of rate-dependent electrochemical performance degradation in cathodes is crucial to developing fast charging/discharging for Li-ion batteries. Here, taking Li-rich layered oxide Li1.2 Ni0.13 Co0.13 Mn0.54 O2 as model cathode, mechanisms at low and high rates are comparatively investigated from two aspects, transition metal (TM) dissolution structure change. Quantitative analyses combining spatial-resolved synchrotron X-ray fluorescence (XRF) imaging, diffraction...
Abstract Li + /Na exchange has been extensively explored as an effective method to prepare high‐performance Mn‐based layered cathodes for Li‐ion batteries, since the first report in 1996 by P. G. Bruce (Nature, 1996. 381, 499–500). Understanding detailed structural changes during ion‐exchange process is crucial implement synthetic control of cathodes, but less studied. Herein, situ synchrotron X‐ray diffraction, density functional theory calculations, and electrochemical tests are combined...
Sodium-ion batteries (SIBs) are now emerging as a low-cost alternative to the current lithium-ion batteries, but their performance is limited by sluggish transportation of large Na ions in electrodes. Expanded graphite has been employed enhancing transport kinetics. However, high-performance should be synthesized at high temperatures when using traditional methods, which inevitably increases total cost material production. To tackle kinetic issue for SIBs, we develop three-dimensional...
Background: Atherosclerosis (AS) is a leading cause of cardiovascular diseases, characterized by lipid accumulation in arterial walls. The enzyme Ephx2 (soluble epoxide hydrolase, sEH) implicated AS development, but its precise mechanisms and therapeutic potential are not fully understood. Objectives: This study aimed to analyze gene expression data from low-density lipoprotein receptor knockout (LDLR⁸/⁸) LDLR⁸/⁸sEH⁸/⁸ mice identify significant genes associated with AS. Methods: A directed...
Transition metal nitrides (TMNs) have received special concern as important energy storage materials, owing to their high conductibility, good mechanical strength, and superior corrosion resistance. However, insufficient capacitance poor cycling stability limit practical applications for supercapacitors. Here, a novel three-dimensional (3D) self-supported integrated electrode consisted of porous nanowall arrays ultrafine cobalt nitride (Co4N) nanoparticles encapsulated in lanthanum...
Lithium-excess manganese layered oxide Li2 MnO3 , attracts much attention as a cathode in Li-ion batteries, due to the low cost and ultrahigh theoretical capacity (≈460 mA h g-1 ). However, it delivers reversible practical (<200 ) irreversible oxygen redox at high potentials (>4.5 V). Herein, heavy fluorination (9.5%) is successfully implemented anionic framework of Li-Mn-O-F (LMOF) through unique ion-exchange route. F substitution with O stabilizes framework, completely inhibits O2...
High-surface-area carbon (HSAC) has been regarded as one of the most promising anode materials for sodium-ion batteries. However, it generally suffers from low initial Coulombic efficiency (ICE), which is closely related to formation process a solid electrolyte interface (SEI). Herein, impact different salts on electrochemical performance and SEI commercial HSAC studied. It found that use NaCF3SO3 enables much higher ICE (69.28%) reversible capacity (283 mA h g-1) compared with NaPF6...
The purpose of this study is to compare the effects and safety azelnidipine amlodipine in Chinese essential hypertensive patients. Patients were randomized receive administration 8–16 mg/day or 2.5–5 for 8 weeks. blood pressure pulse rate evaluated an outpatient clinic by ambulatory monitoring. There 220 patients enrolled study. both groups was decreased significantly (P < 0.001). Compared with amlodipine, received had better response systolic (SBP) diastolic (DBP) 0.01). No significant...
Heterostructured Electrocatalysts In article number 2102413, Baocang Liu, Rui Gao, Jun Zhang, Bin and co-workers report the construction of a novel heterostructured electrocatalyst CePO4/MoP/carbon cloth (CC) constituting MoP nanobelts with surface-decorated CePO4 nanoparticles on CC for hydrogen evolution reaction (HER). The CePO4/MoP/CC exhibits low overpotential 48 mV at 10 mA cm−2 in alkaline medium due to optimized electronic structure more exposed active sites.
Houshiheisan (HSHS) has been effective in the treatment of ischemic stroke (IS) for centuries. However, its mechanisms are still underexplored.
In the practical operations of Li-ion batteries, inevitable deep charge/discharge happens locally due to intrinsic (de)lithiation inhomogeneity at electrode and particle level, which would damage health batteries even cause safety concern. It is essential develop stable cathodes operating in a wide voltage window ensure batteries.
