Abstract Low temperatures severely impair the performance of lithium-ion batteries, which demand powerful electrolytes with wide liquidity ranges, facilitated ion diffusion, and lower desolvation energy. The keys lie in establishing mild interactions between Li + solvent molecules internally, are hard to achieve commercial ethylene-carbonate based electrolytes. Herein, we tailor solvation structure low-ε solvent-dominated coordination, unlock via electronegativity regulation carbonyl oxygen....
Controlling the interfacial chemistries of cathode and anode in potassium ion full-cells is critically important for better K+ storage; however, correlation between electrolyte interphase (CEI) solid (SEI) its effect on electrochemical performance poorly understood, not mention their rational matchup. In this study, an modification strategy has been employed tailored design both CEI a K2Fe[Fe(CN)6] (KFeHCF) surface SEI graphite (Gr) surface. The optimized matchup realized good rate cycling...
Potassium vanadium fluorophosphate (KVPO 4 F) is regarded as a promising cathode candidate for potassium-ion batteries due to its high working voltage and satisfactory theoretical capacity. However, the usage of electrochemically inactive binders redundant current collectors typically results in inferior electrochemical performance low energy density, thus implying important role rational electrode structure design. Herein, we have reported scalable cost-effective synthesis cellulose-derived...
The development of metallic K is seriously hampered by low melting point, high reactivity, and uncontrollable dendrite growth. Herein, benefiting from the super-potassiophility CNTs (carbon nanotubes), K@CNT composite anodes are prepared via a rational fused-modeling approach, where build interconnected frameworks atoms anchored on CNTs, inducing depressed atomic creeping flowability at temperatures. Thereby, deliver flexibility, processability (∼30 μm), thermal stability (up to 300 °C). In...
During oxygen steelmaking process, a systematical description of the interaction behaviour between top blown jet and molten steel is extremely important.

Methods and Results We randomly assigned 120 piglets three groups: control group (a basal diet), probiotics diet supplemented 4 × 109 CFU per gram Bacillus licheniformis-Bacillus subtilis mixture; BLS mix), 0·04 kg t−1 virginiamycin, 0·2 colistin 3000 mg kg−1 zinc oxide). All groups had five replicates...
Fluorochemicals are a rapidly expanding class of materials used in variety fields including pharmaceuticals, metallurgy, agrochemicals, refrigerants, and particular, alkali metal ion batteries. However, achieving one-step synthesis pure fluorophosphate compounds well-controlled manner remains formidable challenge due to the volatilization fluorine during heat treatment process. One feasible method is cleave C-F bond polytetrafluoroethylene (PTFE) create fluorine-rich atmosphere strongly...
The flow field in the over-expanded single expansion ramp nozzle (SERN) demonstrates pronounced separation, intricate interactions involving intersecting and reflecting shocks, mutual interference between shocks boundary layers. Discrepancies arising from cold experiments vs. actual operational conditions introduce a notable influence of specific heat ratio (γ ) on shock angles shock/boundary layer interactions, thereby impacting entire field. In this study, differences inside operating are...
