Ammonium vanadate (NH 4 V 4 O 10 ) is a prominent cathode material for zinc ion storage owing to the abundant active sites, tunable layered structure, and the multivalence state of vanadium ions . Despite the great potential of NH 4 V 4 O 10 , it is constrained by its weak fastness and homogeneity with substrates. A key issue with poor energy storage of flexible battery is extremely low active material load quality. Additionally, the severe self-aggregation phenomena and the brittle interlayer structures are the cause of the rapid capacity fading and the poor rate capacities. Herein, a novel flexible self-support carbon cloth (CC)-based NH 4 V 4 O 10 (CC@NH 4 V 4 O 10 ) cathode was rationally fabricated via a simple hydrothermal method . Apart from serving as a flexible interconnected conductive network, CC can provide uniform nucleation centers and induces ordered growth of NH 4 V 4 O 10 , which effectively reduces its agglomeration problem. The synthesized NH 4 V 4 O 10 nanoribbons exhibit a unique micropore structure with enlarged interlayer spacing, which ensures rapid co-transfer of H + /Zn 2+ ions with enhanced storage capacity. The CC@NH 4 V 4 O 10 cathode delivers a stable specific capacity of 330 mAh g −1 at 0.25 A g −1 with almost no capacity fading (99% capacity retention) over 600 cycles at 5 A g −1 . More impressively, the as-prepared package battery offers outstanding operation stability to power electronics under the low temperature, and it is able to maintain 76% energy retention after 100 cycles at 0 ℃ at a 0.5 A g −1 current density. This high-performance flexible battery may open a new prospect in wearable energy storage applications.

Flexible zinc-ion batteries with hydrogel electrolytes are the most perspective energy-storage systems for wearable applications because of their low cost, safety, abundant zinc reserves, and environmental compatibility. Hydrogel electrolytes have been shown to mitigate the growth of zinc dendrites compared with liquid electrolytes, but dendrites remain the main issue limiting the lifespan of flexible batteries. The relationship between structural and mechanical properties of hydrogels and dendrite growth is unclear, which hinders the efficient development of long-life flexible batteries. Herein, the impact of the microstructure and mechanics of hydrogels on the morphology of zinc deposition was investigated systematically, as well as the influence of current density. Hydrogels with lower porosity allowed for denser zinc plating during initial and long-term cycles since their high Young's modulus and the uniform distribution of micropores led to dendrite suppression by mechanical pressure and regulated ion transport, respectively. However, hydrogel electrolytes with higher porosity resulted in higher stability after long-term cycles because of enhanced mechanical recovery and because the voids generated between the hydrogel and electrode during electroplating and stripping were recovered. Besides, with increasing current density, the deposition layer became thicker and more uneven, thereby reducing the lifetime of zinc batteries. Our study depicts the desired microstructure and mechanical features of hydrogel electrolytes, and could pave the way for the development of flexible long-life zinc-ion batteries.

Currently, mechanically flexible and strong batteries are desired for the development of bendable and portable devices. To meet this requirement, a simple and scalable synthesis of the anode for flexible wire-shaped lithium-ion batteries has been developed by a facile one-step in situ polymerization method. Polypyrrole was found to grow on the surface of Si nanoparticles and attach to twisted carbon fibers. The formed cross-linked structure of Si/PPy along with carbon fiber substrate offers a consecutive electron transport network and a porous structure to adjust large volumetric changes of Si particles during charging and discharging processes. On fabricating the wire-shaped Li-ion battery, the interconnected Si/PPy/CF hybrid electrode was found to offer an excellent performance of 3.9% capacity decrease after the flexibility test, a greatly improved cycling capacity of 2287 mA h g−1 and a capacity retention of about 75% after 100 cycles of the half-cell test. The all-wet methodology may provide a promising route for a new scalable way to produce applicable wire-shaped electrode in battery fabrication.

The practical application of yarn electrode materials has been restricted because of the inherent insulating properties and adverse electrochemical properties of conventional yarns. The aim of the study was to make yarn electrodes with higher specific capacitance and construct a type of yarn-like manganese dioxide (MnO2) electrode. In this work, polyacrylonitrile-wrapped carbon fibers (CFs) core-spun yarn (CFP core spun yarn) was prepared by electrospinning with CF yarn as the base material. The highly conductive yarn (CFPP yarn) was then prepared by depositing polypyrrole nanoparticles by in situ polymerization on top of the CFP cored yarn. Finally, based on CFPP yarn, the CFPP@MnO2 yarn cathode material was prepared by coating MnO2 on CFPP yarn by an impregnation coating method. The CFPP@MnO2 yarn cathode showed outstanding electrochemical performance in the three-electrode system test, maintaining 89.76% of the initial capacity after 100 charge–discharge cycles at a current density of 1 mA cm–1, which indicates that the CFPP@MnO2 yarn cathode has outstanding cycling stability. The yarn cell can therefore be used as the cathode electrode for yarn batteries, providing an effective strategy for applications in smart textiles and wearable electronics.

The inherent trade-off between mechanical robustness and ionic transport efficiency in gel electrolytes has posed a long-standing challenge for advancing solid-state zinc-air batteries. Conventional approaches struggle to reconcile micron-scale pores (essential for mechanical reinforcement) with macroporous networks (critical for rapid ion migration). In this study, a novel strategy was employed to introduce micropores onto the skeleton of a macroporous gel. The X-ray tomography reveals this secondary structure for the first time. The zinc-air battery assembled by this gel exhibit the high ion conductivity of 205 mS cm −1 and undertake a stress of 984 Kpa. Additionally, the lifetimes of button cell and flexible Zinc-air battery reach 120 h and 97 h respectively.

The quest for next-generation energy storage systems has led to the development of high-voltage all-solid-state lithium metal batteries (ASSLMBs), which promise unprecedented energy density and safety. However, the challenge lies in creating of a robust electrolyte that can meet high room temperature ionic conductivity, Li-ion transference number and a wide electrochemical stability window (ESW) while maintaining flexibility and compatibility with lithium metal anodes. Here, novel polyurethane-based composite polymer electrolytes (CPEs) have been successfully fabricated by the cross-linking reaction of poly(1,5-dioxepan-2-one) diols (poly(ether-ester) soft segment) and hexamethylene diisocyanate trimer (hard segment) (PDH) blending with inorganic NASICON-type ceramic fillers Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (PDH@LATP). The resulting CPE exhibits an impressive ionic conductivity of 1.65 × 10 −4 S cm −1 at room temperature and a Li-ion transference number of 0.63, which is attributed to the amorphous structure of PDH and the formation of an interconnected ionic pathway by the inorganic filler. The incorporation of LATP also improve the ESW of CPE to 5.3 V while maintaining good mechanical properties. Therefore, the assembled LiFePO 4 /PDH@LATP/Li batteries displayed low interfacial resistance, Li dendrite suppression, high specific capacity and excellent cyclic performance. The high-voltage LiNi 0.5 Co 0.2 Mn 0.3 O 2 /PDH@LATP/Li batteries also exhibits good cycling performance and durability. The design principles and materials presented herein provide a blueprint for the next wave of ASSLMBs.

Zinc–air batteries (ZABs) are considered a promising energy storage technology due to their high energy density and environmental friendliness. However, the development of efficient and durable oxygen reduction reaction (ORR) catalysts remains a challenge. Herein, we report the synthesis of a highly efficient CoP/Cu3P@NC catalyst using a Zn-MOF template, which was transformed into N- and C-doped bimetallic phosphides via high-temperature phosphating. The CoP/Cu3P@NC-based ZAB exhibits remarkable performance with an open-circuit voltage of 1.50 V, a peak power density of 215 mW cm−2, and a specific capacity of 691 mA h gzn−1, outperforming conventional Pt/C-based ZABs. The catalyst maintained 93.5% of its initial activity after 300 h of cycling, demonstrating its excellent long-term stability. Furthermore, CoP/Cu3P@NC was applied in flexible ZABs, achieving a power density of 74 mW cm−2 and showing stable performance under various bending conditions. The superior performance is attributed to the synergistic effects of Co and Cu, optimized structural properties, and high porosity, enhancing mass transfer and oxygen activation. These results suggest that CoP/Cu3P@NC is a highly promising ORR catalyst for next-generation ZABs, offering both high efficiency and durability in flexible and conventional energy storage applications.

Traditional lithium-ion batteries based on liquid electrolytes cannot adapt to the increasing and various highly flexible requirements. In this work, a confinement-driven strategy has been developed to confine the ionic liquids in a polyhedral oligomeric silsesquioxanes (POSS) and poly(ethylene glycol) diacrylate (PEGDA) hybrid cross-linked poly(ionic liquid)s ionogel (POSS-CPIL-n), which endows this novel electrolyte superior flame retardancy and dramatically flexibility. The POSS-CPIL-n ionogel renders exceptional flexibility (bend, fold and twist) and desired mechanical properties (2.5 MPa). Advantageous for high dissociation of lithium salt , high ionic conductivity (2.5 mS cm −1 at 25 °C) and considerable lithium ion mobility (0.51) are provided. Thanks to the flexibility of ionogel electrolyte together with excellent thermal and electrochemical stability, the LiFePO 4 ||Li cell based on POSS-CPIL-n exhibits significant rate performance and cycling stability, the capacity of the cell can reach to 100 mAh g −1 at 4 C and maintain a substantial discharge capacity of 160.5 mAh g −1 after 200 cycles at 0.2C. Furthermore, the soft-package assembled with POSS-CPIL-n can successfully charge a cell phone and continue to supply power stably even when the battery is exposed to the air, which indicates that POSS-CPIL-n has a promising potential application in high safety flexible electronic devices.

Aqueous rechargeable Ni/Fe batteries are appropriate energy storage devices for portable and wearable electronics due to their outstanding safety and cost-effectiveness. However, their energy storage properties are limited by the sluggish kinetics of iron-based anodes. Herein, we design and construct a high-performance iron-based material with a hierarchical structure developed by electrodepositing iron oxide (Fe 2 O 3 ) nanosheets on titanium carbide (Ti 3 C 2 T x ) MXene nanoplates modified carbon fiber (3D-MXene/Fe 2 O 3 ). Taking advantage of the interaction between Fe 2 O 3 and the terminal functional groups on Ti 3 C 2 T x MXene, such a hierarchical structure offers improved conductivity, enhanced ion-diffusion paths, and high electrochemical stability. The fabricated 3D-MXene/Fe 2 O 3 anode delivers a high volumetric specific capacity of 38.2 mAh cm −3 , and improved capacity retention. After being coupled with NiCoO cathode, the fibrous Ni/Fe battery shows a maximum volumetric specific capacity of 35.1 mAh cm −3 and an extraordinary energy density of 56.2 mWh cm −3 . Meanwhile, the as-prepared Ni/Fe battery confirms good cycling durability (92.9% for 12,500 cycles), and mechanical flexibility also verifies the potential practical application of our device. Thus, this study can provide a powerful route toward high-performance anodes for next-generation wearable energy storage devices.

Alkaline nickel-zinc (Ni-Zn) batteries are considered as one of the most promising rechargeable battery systems. However, the poor cycling stability of the Ni cathode limit their service life. Herein, a conductive polymer (PEDOT:PSS) encapsulated Ni 3 S 2 hollow nanorod structure via facile immersion is proposed. PEDOT:PSS coating layer can not only provide adhesion for Ni 3 S 2 nanorods to prevent Ni 3 S 2 from falling off the substrate during cycling, but also facilitate electron transfer via the complete conductive pathway. The hollow nanorods structure of Ni 3 S 2 is beneficial to mitigate the volume change and accelerate the rapid transport of ions. Besides, a gel electrolyte with double network porous structure in our battery system is well designed. The ionic association of sodium alginate on Zn 2+ can effectively reduce the activity of bound water molecules in the solvation sheath of Zn 2+ , inhibit the side reaction and dendrite generation through the ion-confinement effect, to achieve uniform deposition of zinc ions . As a consequence, the as-designed quasi-solid-state flexible Ni-Zn battery demonstrates a high specific capacity of 1.06 mAh cm −2 (276.04 mAh g −1 ) at 8 mA cm −2 and an ultra-long cycle stability over 10,000 cycles with a capacity retention of 88.96% at 30 mA cm −2 .

The silicon microparticles (SiMPs) offer a promising solution for high-energy-density lithium-ion battery systems. However, the inevitable volume expansion (>300%) of SiMPs during alloying often leads to particle breakage, interface rupture, and electrode separation, resulting in rapid capacity decay. Herein, an effective strategy is proposed for designing a novel solid–liquid hybrid electrode (Si@EGaSn) for high-energy-density flexible lithium-ion batteries. The Si@EGaSn electrode has a liquid-phase top layer containing SiMPs and a solid-phase copper gallium alloy bottom layer. The top layer can not only electrically connect the fractured SiMPs, but also form a stable solid electrolyte interface during alloying processes. The bottom layer can firmly adhere the electrodes to the current collector. Consequently, the optimal Si@EGaSn electrode delivers a highly reversible capacity of 767.1 mAh g −1 at 0.5 A g −1 and a high capacity retention of >99% during 200 cycles. After loading the electrode into metallic textiles, the assembled high-voltage pouch cell of NCM811//Si@EGaSn shows a high areal capacity of 3.2 mAh cm −2 , high volumetric energy density of 500 Wh L −1 and negligible capacity decay during 3000 flexing cycles at a small bending radius of 4.0 mm. This work provides a new electrode design approach to achieve high-energy-density flexible lithium-ion batteries.

All-solid-state bulk-type lithium ion batteries (LIBs) are considered ultimate solutions to the safety issues associated with conventional LIBs using flammable liquid electrolyte. The development of bulk-type all-solid-state LIBs has been hindered by the low loading of active cathode materials, hence low specific surface capacity, and by the high interface resistance, which results in low rate and cyclic performance. In this contribution, we propose and demonstrate a synergistic all-composite approach to fabricating flexible all-solid-state LIBs. PEO-based composite cathode layers (filled with LiFePO4 particles) of ∼300 μm in thickness and composite electrolyte layers (filled with Al-LLZTO particles) are stacked layer-by-layer with lithium foils as negative layer and hot-pressed into a monolithic all-solid-state LIB. The flexible LIB delivers a high specific discharge capacity of 155 mAh/g, which corresponds to an ultrahigh surface capacity of 10.8 mAh/cm2, exhibits excellent capacity retention up to at least 10 cycles and could work properly under harsh operating conditions such as bending or being sectioned into pieces. The all-composite approach is favorable for improving both mesoscopic and microscopic interfaces inside the all-solid-state LIB and may provide a new toolbox for design and fabrication of all-solid-state LIBs.
