Commercialization of rechargeable lithium metal batteries has long been hindered by the safety concerns associated with the undesirable lithium dendrite issues. To inhibit the uncontrolled dendrite growth, homogeneous ion transport to achieve even lithium plating is a necessity for lithium anode, but remain challenging. Inspired by traditional Li x MnO 2 materials with a fast Li + transport, here we constructed 3D ionic-electronic transport channels with in-situ electrochemically lithiated MnO 2 . Taking advantages of the inherently fast ion transport and 3D conductive network, homogeneous ionic flux and reduced local current density can be achieved with this scaffold, contributing to even nucleation and uniform distribution of lithium plating. The dendrite-free anode shows a stable Li stripping/plating process with a low overpotential, and the full cell coupling the composite anode with LiFePO 4 cathode delivers excellent cycle stability and rate capability. Our strategy offers a new avenue to advance next-generation lithium metal batteries.

Currently, the practical application of SiO x still has a huge hindrance in the area of lithium ion battery, because it is unable to achieve an effective contact with surrounding conducting materials, resulting in failure to form lithium ion migration tunnels. In this work, we presented a facile method to synthesize the B-doped SiO x composite by adhering SiO x particles with MWCNT (multi-walled carbon nanotube) under the assistance of lithium metaborate (LiBO 2 ). LiBO 2 , as a sintering aid, not only can react with SiO x to form a compacted framework, but also build a three-dimensional (3D) conductive network for ions transportation. Furthermore, B-SiO x @CNT@LBO anode delivers a remarkable lithium storage performance in terms of long cycles and high rate capability. A full cell coupled with NCM622 cathode achieves a high energy density of 429.5 Wh kg −1 based on the total mass of cathode.

A carbon nanohybrid Pickering stabilizer was synthesized by the hydrothermal reaction of 2-ethyl-4-methylimidazole (EMI), graphene oxide (GO), and carbon nanotubes (CNTs). A water-in-oil (w/o) type Pickering emulsion was achieved using the mixed carbon nanohybrids/Span 80 to form a porous and conductive polyacrylonitrile (PAN) nanocomposites after polymerization. Contact angle and X-ray photoelectron spectroscopy (XPS) results show that the carbon nanohybrid stabilizer is amphiphilic. The effects of the composition and concentration of stabilizers were investigated. When the concentration of the carbon nanohybrid stabilizer is 4 mg ml −1 , the conductivity of the resulting material is 2.31 × 10 −9 S m −1 , which is six orders of magnitude higher than that of porous PAN composites without carbon nanohybrid stabilizer. At the mass ratio of 6GO:1CNTs, the conductivity of porous PAN-based composites reaches 2.47 × 10 −8 S m −1 . The significantly increased conductivity is the evidence for the three dimensional conductive network constructed by carbon nanohybrid stabilizer at the oil/water interface.

Two-dimensional materials, such as MXene (Ti 3 C 2 T x ), have recently garnered significant attention in the field of energy storage. However, their electrochemical performances are severely hindered by the tendency of their layered structures to restack. This study introduces an innovative strategy involving the in-situ polymerization of polypyrrole (PPy) microspheres on the surfaces of aramid nanofibers (ANFs) to form a stable PPy@ANFs core–shell structure. This structure serves as a conductive framework intercalated between Ti 3 C 2 T x nanosheets, producing an MXene/PPy@ANFs (MPA) aerogel with three-dimensional multidirectional conductive properties. The PPy@ANFs core–shell structure not only widens the ion transport pathways, but it also significantly inhibits the restacking of the Ti 3 C 2 T x layers. Additionally, the resulting interlayer spacing of the MXene effectively mitigates the swelling and pulverization of the PPy microspheres. This ternary synergistic effect endows the MPA 0.3 aerogel with a high specific capacitance of 404.9 F g −1 at 2 mV s −1 . Symmetric supercapacitors assembled with this material exhibit exceptional comprehensive performance, namely a specific capacitance of 169.84 F g −1 at 2 mV s −1 , a capacitance retention of 82 % at a high scan rate of 100 mV s −1 , and a capacity retention of 99.31 % after 10,000 cycles at a current density of 8 A g −1 . Furthermore, at a current density of 1 A g −1 , the device simultaneously achieves an energy density of 22.12 Wh kg −1 and a power density of 1280 W kg −1 . This work presents a novel three-dimensional structural design for MXene-based composites, providing valuable insights into their potential for advanced energy storage applications.

In traditional Si-based anodes, bio-based binders can partially address the inherent drawbacks of silicon anodes. However, plenty of inactive materials hinder the improvement of the electrochemical performance of traditional Si-based anodes. To settle the issues above, sodium alginate (SA)/chitosan (CS) double-network is constructed to design a free-standing Si anode. The two physically cross-linked networks, reinforced by carbon nanotubes (CNTs), form a 3D-structured electrode that firmly anchors Si nanoparticles via forming dynamic hydrogen bonds. Furthermore, the in-situ -reduced copper particles act as the point-like conductive agent, CNTs function as the connecting conductive networks, and SA/CS aerogel sheets serve as the conductive plane, synergistically forming a three-dimensional conductive network (points-lines-planes) around Si particles. This double-network structure effectively alleviates Si volume expansion and endows the free-standing electrode with a high capacity of 1194 mAh/g (based on the whole weight of the electrode) and an excellent capacity retention rate of 85.1% after 100 cycles at 0.5 A/g. This strategy is anticipated to produce high-performance free-standing silicon anodes, therefore supporting lightweight and high-capacity electronics.

In this study, a unique dual-spatial three-dimensional (3D) porous structure comprising Ni/C hollow microspheres was prepared from a Ni-based metal organic framework (Ni-MOF) embedded in graphene foam (GF) by the solvothermal method followed by calcination . The graphene foam-based composite, Ni/C@GF (NCGF), exhibited a stable spatial conductive network structure and diverse porous architecture, promoting the microwave absorption (MA) properties of composites. The NCGF with a Ni/C and GF ratio of 1:2.5 displayed a reflection loss (RL) value of ─63 dB with 15 wt% loading, while the thickness is only 1.76 mm. Further, its effective absorption bandwidth (EAB) reached to 5.4 GHz at 2 mm thickness. In addition, when the RL value is less than ─20 dB, the NCGF still manifests a wider bandwidth (2.2 GHz) and a relatively low thickness (1.76 mm). In addition to the extraordinary attenuation ability, the excellent MA performance is mainly ascribed to optimized impedance matching characteristics. Moreover, multiple reflections promoted by the dual-space structure also play a significant role during the microwave absorption process.

The integration of micro-sized silicon (μm-Si) with high theoretical capacity and structurally stable graphite (Gr) has great potential in promoting the next generation of lithium-ion battery anodes. However, the application of Gr/μm-Si anodes is impeded by the excessive solid electrolyte interphase (SEI) accumulation and electrical disconnection caused by μm-Si swelling and fracturing. Herein, a multifunctional carbon layer (MCL) composed of in situ grown carbon nanotubes (CNTs) and pyrolytic carbon derived from polyacrylonitrile is prepared to optimize Gr/μm-Si anode material. The pyrolytic carbon serves to anchor the CNTs and isolate the μm-Si surface from the electrolyte, mitigating side reactions and ensuring stable SEI formation. The CNTs create a robust three-dimensional conductive network, providing mechanical buffering for μm-Si volume expansion while enhancing electron and ion transport. Accordingly, the Gr/Si@MCL anode exhibits a discharge specific capacity of 503.6 mAh g −1 , maintaining an exceptionally low capacity decay of just 0.031% per cycle after 500 cycles at a current density of 1 A g −1 . Furthermore, the Gr/Si@MCL||LiFePO 4 full-cell demonstrates excellent performance, particularly with a high energy density of 347 Wh kg −1 . These results highlight the potential of the proposed structure design for advancing the practical deployment of Gr/μm-Si anodes in next-generation energy storage devices.

High temperature sodium batteries with inorganic electrolytes are attracting increasing attention due to their high thermal stability, reliability, long-cycle life and safety. Despite the intensive investigation of Na-NiCl 2 batteries during last decades, designing a stable conducting network in the cathode is still challenging but desirable. In this work, a new cathode structure composed of Ni nanowires with an effective electron conducting network is proposed for planar sodium–nickel chloride batteries . During the first stage of charge, Ni nanowires reacted with Cl ion to form NiCl 2 on the surface and the excessive Ni nanowires inside can serve as conducting framework to facilitate the fast electron transport . As expected, the metal nanowires show a high specific capacity of 130 mA h g −1 (∼14 mAh cm −2 ) at 0.05 C after 100 cycles. Meanwhile, the batteries show stable cycling performance at 0.05 C with a high cut-off energy density of 360 W h kg −1 , much higher than the traditional tubular sodium-nickel chloride batteries (∼100 Wh kg −1 ). Scanning electron microscope (SEM) images of the cathode after long cycling reveal the ultra-slow growth of Ni particles, confirming the excellent stability of the prepared nanowires cathode.

To address the safety limitations of liquid electrolytes and performance bottlenecks in conventional energy storage devices, a high-concentration polymer-in-salt polymer solid electrolyte (PiS-PSE) and a 3D conductive network-engineered niobium pentoxide (Nb 2 O 5 ) composite anode for solid-state hybrid lithium-ion capacitors (HLICs) are developed. The optimized lithium bis(trifluoromethanesulfonyl)imide/poly(vinylidene fluoride -co -hexafluoropropylene) (LiTFSI/PVDF-HFP) electrolyte (mass ratio 3:1) achieves an ionic conductivity of 2.09 × 10 − 3 S cm −1 at 20 °C with enhanced electrochemical stability (>4.5 V vs. Li/Li + ). Simultaneously, the Nb 2 O 5 /graphene-carbon nanotube hybrid anode (NGNT-90%) exhibits exceptional pseudocapacitive behavior and rate capability (171 mAh g −1 at 0.1C). The integrated solid-state HLIC delivers a high energy density of 108.3 Wh kg −1 at 100 W kg −1 and maintains 37.63 Wh kg −1 at 500 W kg −1 , which is comparable with reported liquid-based LICs. Critically, the device demonstrates >80% capacitance retention after 300 cycles at 5C with near-unity coulombic efficiency (≈99.0%), attributable to stable electrode/electrolyte interfaces and dendrite-suppressing characteristics of the PiS-PSE. This work provides a material design paradigm for next-generation safe, high-performance electrochemical energy storage systems.

Inferior specific capacity and sluggish redox kinetics are the most stubborn problems lithium-ion and lithium-sulfur batteries (LIBs and LSBs) are facing, respectively. Here we report a facile fabrication of self-supported hollow Co 3 O 4 @carbon nanotubes on carbon cloth (H-Co 3 O 4 @CNT/CC) through a mild pyrolysis-oxidation process. The additive- and binder-free H-Co 3 O 4 @CNT/CC shows excellent electrochemical performances as both LIBs and LSBs electrodes. As a robust integrated anode for LIBs , the areal capacities are 2.72 mAh cm −2 at the current density of 0.5 C over 1000 cycles. While as a durable cathode host for LSBs, favorable areal capacities of 2.37 mAh cm −2 are maintained with a low capacity decay of 0.11 % per cycle at the sulfur loading of 6 mg cm −2 and current density of 1 C after 400 cycles. Electrochemical technology, ex situ Raman spectroscopy and DFT calculations are performed to comprehensively analyze H-Co 3 O 4 @CNT/CC via thermodynamics and kinetics. It is demonstrated that the hierarchically hollow interior structure, strong adsorb ability of Co 3 O 4 toward polysulfides and three-dimensional (3D) inter-connected conductive carbon framework are responsible for the high areal capacity, fast redox kinetics and cycling durability.

The progress in energy storage technology has primarily focused on practical applications, necessitating straightforward fabrication, economical materials, and scalable manufacturing. In this work, we demonstrate a facile method to prepare highly self-catalytic cathodes for lithium‑oxygen batteries (LOBs) using bacterial cellulose (BC) as a precursor. The BC-derived cathodes (CBC) retain both the fibrous structure and oxygen-functional groups of the original biomass, producing a material with a modest appearance but outstanding electrochemical properties. The oxygen-functional groups incorporated into the carbon framework exhibit synergistic catalytic effects, enabling an unprecedented discharge capacity of 33,900 mAh g −1 at 200 mA g −1 , significantly outperforming most reported cathodes. An integrated oxygen-selective membrane, formed via a facile silicone oil coating process, resulting in stable cycling at current densities up to 1000 mA g −1 and continuous operation for over 240 h in ambient air when coupled with a hybrid polymer electrolyte, highlighting its practical viability. Furthermore, the eco-friendly and self-catalytic CBC represents an innovative “three-in-one” electrode design, simultaneously providing a 3D conductive network, efficient catalytic centers, and selective oxygen transport capabilities, all crucial features for next-generation energy storage systems.

A three-dimensional (3D) interconnected graphene nanoribbons (GNRs) framework wrapping double nanoshells of SnO 2 @TiO 2 was synthesized by a simple but effective method. The nanoshell of TiO 2 anchored on the surface of SnO 2 nanoshell with hollow core to restrict large volume expansion, then GNRs wrapped and interlaced double nanoshells of SnO 2 @TiO 2 to construct a continuous 3D conducting network. The double protection strategy of active electrode materials can make full use of the function of the three components. The enhanced electrochemical performance can be attributed to the structural stability, excellent electronic conductivity and high electrochemical reaction activity.
