Abstract Ni‐rich layered oxides are promising cathode material for high‐energy‐density lithium‐ion batteries (LIBs). However, they suffer from poor capacity retention due to unstable structures. Herein, a strategy of high‐valence W doping is put forward tune the nanometer‐sized crystal domains and reshape primary particle textures, which can stabilize structure against formation microcracks improve electrochemical performance. The oxide with 0.5 mol% doped delivers high‐capacity 91.6% up 300...
We describe a facile route to the straightforward fabrication of nanoporous (NP) PtRu alloys with predetermined bimetallic compositions. Electron microscopy and X-ray diffraction characterizations demonstrate that selective etching Al from ternary PtRuAl source generates three-dimensional bicontinuous NP-PtRu alloy nanostructures single-phase face-centered-cubic crystalline structure. photoelectron spectroscopy shows slight electronic structure modification Pt by alloying Ru as well uniform...
Abstract Resources used in lithium‐ion batteries are becoming more expensive due to their high demand, and the global cobalt market heavily depends on supplies from countries with geopolitical risks. Alternative battery technologies including magnesium‐ion therefore desirable. Progress toward practical impeded by an absence of suitable anodes that can operate conventional electrolyte solvents. Although alloy‐type compatible common solvents, they suffer severe failure associated huge volume...
Abstract Sodium ion capacitors (SICs) show high energy/power densities owing to the special dual‐ion energy storage mechanism with cation intercalation and anion adsorption. However, strong ion‐solvent interactions make it difficult for interfacial desolvation, which not only limits transport kinetics, but also results in solvent co‐intercalation into electrode materials. Here, an advanced zwitterionic gel polymer electrolyte (GPE) is developed weaken interactions. The...
A mass-produced and low-cost hierarchical mesoporous/macroporous silicon-based composite material with an ample porous structure dual carbon protective layers has been rationally designed constructed. The Si/SiO<sub>2</sub>@C anode materials for LIBs show enhanced electrochemical properties.
Hierarchical LiMn2O4 hollow cubes with exposed {111} planes have been synthesized using cube-shaped MnCO3 precursors, which are fabricated through a facile co-precipitation reaction. Without surface modification, the as-prepared exhibits excellent cyclability and superior rate capability. Surprisingly, even over 70% of primal discharge capacity can be maintained for up to 1000 cycles at 50 C, only about 72 s time materials deliver initial 96.5 mA h g(-1). What is more, 98.4% 90.7% retentions...
Using ai-GCMC simulations, operando WAXS, and kinetics analysis, we found that the high-rate performance of Sb as an alloy anode in Na-ion batteries is due to presence amorphous intermediate phase formed during sodiation desodiation.
Rational chrysanthemum-like TiO<sub>2</sub> nanostructures have been developed by a facile effective approach as the anode materials, exhibiting good lithium storage performances with excellent rate capacity and cycling stability (see picture), which are much better than those of electrodes reported so far under similar testing conditions.
The purpose of this study was to assess the accuracy absolute cerebral blood flow (CBF) measurements obtained by dynamic contrast-enhanced (DCE) near-infrared spectroscopy (NIRS) using indocyanine green as a perfusion contrast agent. For validation, CBF measured independently MRI method arterial spin labeling (ASL). Data were acquired at two sites and under conditions (normocapnia hypercapnia). Depth sensitivity enhanced time-resolved detection, which demonstrated in separate set experiments...
Abstract The execution of individual KMC events can become a major computational bottleneck in the simulation sequences along chains using because complex data storage schemes required to record sequence each chain. event be very time‐consuming searching, moving, and modifying all detailing chain reflect transformation as result chemical reaction computationally expensive. To address this issue, we developed new scheme for recording sequence, which significantly improve calculation speed...
Conventional solid battery anodes suffer from dendrite growth and volume changes, resulting in poor cycling performances. Self-healing electrodes made of liquid metals alloys can overcome these issues by reversibly undergoing liquid–solid phase transformations during (dis)charging. Recently, we achieved 1000 cycles Mg-ion using Ga as the active material, which transformed into Mg2Ga5 (de)magnesiation. However, fundamental mechanism behind this transformation remains unclear. In follow-up...
Manganese-based lithium-rich layered oxides (Mn-LLOs) are promising candidate cathode materials for lithium-ion batteries, however, the severe voltage decay during cycling is most concern their practical applications. Herein, an Mn-based composite nanostructure constructed Li
