Tin and its compounds hold promise for the development of high-capacity anode materials that could replace graphitic carbon used in current lithium-ion batteries. However, introduced porosity electrode designs to buffer volume changes active during cycling does not afford high volumetric performance. Here, we show a strategy leveraging sulfur sacrificial agent controlled utility void space tin oxide/graphene composite anode. In typical synthesis using capillary drying graphene hydrogels, is...
We propose a novel material/electrode design formula and develop an engineered self-supporting electrode configuration, namely, silicon nanoparticle impregnated assemblies of templated carbon-bridged oriented graphene. have demonstrated their use as binder-free lithium-ion battery anodes with exceptional lithium storage performances, simultaneously attaining high gravimetric capacity (1390 mAh g(-1) at 2 A respect to the total weight), volumetric (1807 cm(-3) that is more than three times...

A porous, yet compact, RuO 2 /graphene hybrid is successfully prepared by using a disassembly–reassembly strategy, achieving effective and uniform loading of nanoparticles inside compact graphene monolith. The disassembly process ensures the into monolith, while reassembly guarantees high density simultaneously unimpeded ion transport channel in composite. resulting possesses 2.63 g cm −3 , leading to record volumetric capacitance 1485 F at current 0.1 −1 . When increased 20 it remains 1188...
Maximized utilization of pores and heteroatom functionalities is successfully achieved within the strategically engineered N,P-co-doped polypyrrole-derived carbon nanotube system.
The electrochemical performance of lithium–sulfur (Li–S) batteries can be significantly improved by simply coating a thin barrier layer on the separator. spray-coating mixture graphene oxides (GO) and oxidized carbon nanotubes (o-CNT) achieve only 0.3 mg cm−2, which is much less than conventional interlayers has no negative impact energy density but enhances performances whole battery device. Due to binding forces induced functional groups GO interconnected nanoscale channels provided o-CNT,...
A collaborative strategy is developed for constructing stable lithium metal anodes by using a self-supporting multifunctional host matrix.
Abstract Schiff‐base networks (SBNs), as typical examples of nitrogen‐doped microporous organic polymers (MOPs), exhibit promising application prospects owing to their stable properties and tunable chemical structures. However, band structure engineering, which plays a key role in optical properties, remains elusive due the complicated mechanisms behind energy level adjustment. In this work, series SBNs are fabricated by tailoring ratio p‐phthalaldehyde o‐phthalaldehyde chemistry reaction...
The reduced preoxidized graphene membranes with in-plane porosity were prepared for studying the specific changing water flux.
Abstract To improve the electrochemical performance of carbonaceous anodes for lithium ion batteries (LIBs), incorporation both well‐defined heteroatom species and controllable 3D porous networks are urgently required. In this work, a novel N‐enriched carbon/carbon nanotube composite (NEC/CNT) through chemically induced precursor‐controlled pyrolysis approach is developed. Instead conventional N‐containing sources or precursors, Schiff‐base network (SNW‐1) enables desirable combination...
