For building high‐energy density asymmetric supercapacitors, developing anode materials with large specific capacitance remains a great challenge. Although Fe 2 O 3 has been considered as promising material for the of ‐based anodes is still low and cannot match that cathodes in full cells. In this work, composite well dispersed quantum dots (QDs, ≈2 nm) decorated on functionalized graphene‐sheets (FGS) prepared by facile scalable method. The QDs/FGS composites exhibit up to 347 F g −1 1 m Na...
Fe2O3 nanocrystals were uniformly anchored onto graphene nanosheets (Fe2O3@GNS) by a nanocasting technique, and the resulting composites applied as anodes of sodium-ion batteries. Fe2O3@GNS exhibits excellent cycling performance rate capability.
Porous activated carbon with a ultrahigh specific surface area (3164 m2 g−1) and large pore volume (1.88 cm3 was prepared from waste litchi shells channel-like macropores via KOH activation method. The macroporous structure of is believed to be conducive distribute the agent, which enables sufficient activation. as-prepared developed as conducting framework for lithium–sulfur battery cathode materials. resulting carbon/sulfur composite possesses high capacity, good rate capability, long-term...
Abstract Layered transition metal oxide P2‐Na 2/3 Ni 1/3 Mn O 2 usually suffers from large‐volume phase transitions and different Na‐vacancy ordering during sodium (de)intercalation, incurring rapid capacity decline poor rate capability. Herein, an effective strategy based on synergetic effect of selected multiple ions is designed for P2‐type cathodes with improved performance. The role tetravalent titanium provides high redox potential, inactive divalent magnesium stabilizes the structure,...
Mobility size distributions of soot particles produced from a fuelrich, laminar premixed ethylene flat flame were obtained by in situ probe sampling and online analysis using nano scanning mobility particle sizer. The emphasis the work was development an technique to follow evolution nanoparticles formed flames. Particle distribution functions along centerline spatially resolved manner. Considerable efforts made eliminate losses sample probe. To this end, effect dilution on systematically...
CBC is applied as a framework for sulfur and an interlayer in Li–S batteries. The could prevent over-aggregation on the cathode.
Carbon materials have attracted great interest as an anode for sodium-ion batteries (SIBs) due to their high performance and low cost. Here, we studied natural wood fiber derived hard carbon anodes SIBs considering the abundance cost of wood. We discovered that a thermal carbonization led porous with specific surface area 586 m2 g–1, while pretreatment 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) could effectively decrease it 126 g–1. When evaluating them SIBs, observed resulted in initial...
Garnet-type Li7La3Zr2O12 (LLZO) is among the most attractive candidates for achieving solid-state lithium batteries. LLZO pellets with high density are preferred because of their potential to prevent dendritic Li growth and penetration. However, presence pores inside electrolyte inevitable if it prepared by a traditional reaction. Large numbers have an adverse influence on both ionic conductivity pellets. In this work, we studied origin pore formation in Li6.4La3Zr1.4Ta0.6O12 (LLZTO)...
A porous polyimide (PI) membrane is successfully prepared via nonsolvent-induced phase separation with two porogens: dibutyl phthalate and glycerin. The as-prepared uniform PI shows excellent separator properties for lithium-ion batteries (LIBs). Compared the commercial polyethylene (PE) separator, exhibits significant thermal stability, better ionic conductivity, wettability both in carbonate ether electrolytes LIBs. battery coin-cells assembled more robust still works even after heating at...
Fused deposition modeling (FDM) processed Poly-ether-ether-ketone (PEEK) materials are widely used in aerospace, automobile, biomedical, and electronics industries other due to their excellent mechanical properties, thermal chemical resistance, wear biocompatibility, etc. However, the manufacture of PEEK parts utilizing FDM process faces challenge fine-tuning a list parameters heat treatment conditions reach best-suiting properties microstructures. It is non-trivial make selection only...
A continuous mesoporous iron oxide nanofilm was directly formed on graphene nanosheets through the in situ thermal decomposition of Fe(NO3)3·9H2O and anchored tightly surface. The lithiation-induced strain naturally accommodated, owing to constraint effect structure. Hence, pulverization effectively prevented.
O3-NaNi0.25Fe0.5Mn0.25O2 layered oxide is considered one of the most promising cathode candidates for sodium-ion batteries because its advantages, such as large capacity and low cost. However, practical application this material limited by poor cyclic stability insufficient rate capability. Here, a strategy to substitute Fe3+ in NaNi0.25Fe0.5Mn0.25O2 with Al3+ adopted address these issues. The substitution enhances framework phase transition reversibility parent forming stronger TM–O bond,...
