Achieving high-performance Na-ion capacitors (NICs) has the particular challenge of matching both capacity and kinetics between anode cathode. Here a high-power NIC full device constructed from 2D metal–organic framework (MOFs) array is reported as reactive template. The MOF converted to N-doped mesoporous carbon nanosheets (mp-CNSs), which are then uniformly encapsulated with VO2 Na3V2(PO4)3 (NVP) nanoparticles electroactive materials. By this method, performance battery materials enabled...
Abstract Aqueous zinc‐ion batteries (ZIBs) have become research focus because of their cost‐effectiveness, high safety, and eco‐friendliness. Unfortunately, sluggish Zn 2+ diffusion kinetics the poor cycling stability in cathode materials impede large‐scale application. Herein, V 2 O 5 @poly(3,4‐ethylenedioxythiophene) (PEDOT) hybrid nanosheet arrays are uniformly deposited on carbon cloth (CC) as a superior ZIB cathode. The as‐fabricated @PEDOT/CC electrode displays maximum capacity 360 mAh...
Abstract Metal‐ion capacitors are being widely studied to reach a balance between power and energy output by combining the merits of conventional batteries capacitors. The main challenge for Na‐ion is that battery‐type anode usually has unsatisfactory density long‐term stability since most Na host materials have poor kinetic structural stability. Herein, asymmetric hollow bowl‐like carbon (HBC) rationally designed fabricated through an in situ hard‐template approach. formation originates...

Sanitary tissue is utilized as the precursor to construct a hard carbon microbelt paper (HCMB), which can be employed high-initial-coulombic-efficiency and low-discharge-platform K + -storage anode for 4.5 V hybrid capacitors.
Abstract Hard carbon (HC) has become the most promising anode material for sodium‐ion batteries (SIBs), but its plateau capacity at ≈0.1 V (Na + /Na) is still much lower than that of graphite (372 mAh g −1 ) in lithium‐ion (LIBs). Herein, a CO 2 ‐etching strategy applied to generate abundant closed pores starch‐derived hard effectively enhances Na storage. During etching, open are first formed on matrix, which situ reorganized through high‐temperature carbonization. This ‐assisted...
Abstract Hybrid Na‐ion capacitors (NICs) are receiving considerable interest because they combine the merits of both batteries and supercapacitors low‐cost sodium resources. However, further large‐scale deployment NICs is impeded by sluggish diffusion Na + in anode. To achieve rapid redox kinetics, herein controlled fabrication mesoporous orthorhombic‐Nb 2 O 5 (T‐Nb )/carbon nanofiber (CNF) networks demonstrated via situ SiO ‐etching.

Abstract Sodium–vanadium fluorophosphate (Na 3 V 2 O x (PO 4 ) F 3−2 , NVPF, 0 ≤ 1) is considered to be a promising Na‐storage cathode material due its high operation potentials (3.6–4 V) and minor volume variation (1.8%) during Na + ‐intercalation. Research about NVPF mainly focused on powder‐type samples, while ordered array architecture rarely reported. In this work, large‐area uniform (VO) cuboid arrays are vertically grown carbon nanofiber (CNF) substrates for the first time. Owing...
Hollow micro-/nanostructures are widely explored for energy applications due to their unique structural advantages. The synthesis of hollow structures generally involves a "top-down" casting process based on hard or soft templates.

A thin homogeneous atomic-layer-deposition (ALD) Al2 O3 layer employed confine the pyrolysis precursor fibers, which transform into metal (or oxide)-carbon fibers after removal ....
Sodium-ion batteries (SIBs) hold great promise owing to the naturally abundant sodium resource and high safety. The research focus of SIBs is usually directed toward electrode materials, while binder as an important component rarely investigated.
