Cable‐like V₂O₅ Decorated Carbon Cloth as a High‐Capacity Cathode for Flexible Zinc Ion Batteries

Rechargeable Zn‐ion batteries (ZIBs) are regarded as one of the most promising energy storage systems due to their non‐toxicity, low cost, and non‐flammability features. However, exploring flexible and high‐capacity devices with prominent cycling still remains a challenge for ZIBs. Herein, a flexible and binder‐free carbon cloth coated by V2O5 (namely, CC@V2O5) cathode material is prepared through a simple solvothermal method. The cable‐like CC@V2O5 provides abundant active sites and highways for electrons transport. Meanwhile, the layered structure of V2O5 can also facilitate zinc ion diffusion. The galvanostatic intermittent titration technique indicates that the zinc‐ion diffusion coefficient of CC@V2O5 is much higher than that of the commercial V2O5. As a result, the CC@V2O5 exhibits excellent electrochemical performance and outstanding bendability arising from the synergistic effect between porous V2O5 and carbon cloth, in terms of a remarkable discharge capacity (296 mAh g−1 at 3 A g−1), superior rate capability (241 mAh g−1 at 5 A g−1), and long‐term stability with a capacity retention of 87.1% over 2200 cycles. The novel strategy proposed in this study may provide guidance for exploiting high‐performance flexible systems and wearable energy storage systems.

Metallic zinc (Zn) anode has been received a great promise for aqueous rechargeable zinc-ion batteries (ZIBs) due to its intrinsic safety, low cost, and high volumetric capacity. However, the dendrite formation regarding the surface corrosion is the critical problems to achieve the high performance and the long lifespans of ZIBs. Here, we purpose the facile cyclic voltammetry deposition of polypyrrole/reduced graphene oxide (PPy/rGO) composites coated onto Zn 3D surface as Zn anode for ZIBs. As results, the deposited PPy/rGO layer demonstrates the homogeneous distribution covering onto Zn surface, effectively suppressing the formation of dendrite. Additionally, a symmetric cell of the PPy/rGO coated Zn remarkably enhances an electrochemical cycling with a low voltage hysteresis for zinc plating/stripping, which is superior to the pristine Zn cell. In addition, the deposited layer of PPy/rGO on Zn effectively improves the reactivity of electrochemically active surface area and the intrinsic electronic configurations, participating in extraction/intercalation of Zn2+ ions and leading to enhance ZIBs performance. The coin cell battery of Zn-PPy/rGO//MnO2 can deliver a high initial discharge capacity of 325 mAh/g at 0.5A/g with a good cycling stability up to 50% capacity retention after 300 cycles. Thus, these achieved results of Zn-PPy/rGO//MnO2 battery with dendrite-free feature effectively enhance the life-performance of ZIBs and open the way of the designed coating composite materials to suppress dendrite issues.

Aqueous zinc-ion batteries (ZIBs) with metallic Zn anodes have emerged as promising candidates for large-scale energy storage systems due to their inherent safety and competitive capacity. However, challenges of Zn anodes, including dendrite growth and side reactions, impede the commercialization of ZIBs. The regulation of the Zn/electrolyte interphase is a feasible method to achieve high-performance ZIBs with prolonged lifespan and high reversibility. Considering the as-made artificial interphase is the result of a combination of protection materials, protection mechanisms, and construction techniques, this review comprehensively summarizes the recent progress of interphase modulation and provides a systematic guideline for constructing ideal artificial layers. In addition to revealing the entanglement relationship between the failure behaviors of Zn anodes and timely concluding the emerging protection mechanisms for stable Zn/electrolyte interphase, this review also evaluates the constructing techniques in regard of commercialization, including engineering workflow, strength, shortcoming, applicable materials, and protection effect, aiming to pave the way to practical application. Finally, this review presents noteworthy points of ideal artificial layer. It is expected that this review can enlighten researchers to not only explore ideal interphases of Zn anodes for practical application, but also design other metal anodes in aqueous batteries with similar failure behaviors.
