Special Issue Information

Dear Colleagues,

Flexible and wearable energy storage devices are at the forefront of modern energy storage solutions, catering to the growing demand for portable, lightweight, and adaptable power sources. These energy storage devices are essential for powering next-generation wearable electronics, including smartwatches, fitness trackers, medical devices, and other flexible electronic gadgets. Innovations in materials science, manufacturing processes, and battery design have enabled the development of batteries that are not only flexible but also maintain high energy density, a long life cycle, and safety. Research in this field focuses on novel electrode materials, advanced electrolytes, and innovative fabrication techniques to achieve superior performance and reliability. The integration of these batteries into everyday items offers unprecedented convenience and functionality, revolutionizing how we interact with technology.

Topics of interest include, but are not limited to, the following:

  • Innovations in flexible and stretchable electrode materials;
  • Aqueous flexible batteries system;
  • Development of solid-state, gel, and polymer electrolytes that enhance battery flexibility and safety;
  • Novel fabrication methods like printing, coating, and lamination techniques for flexible and wearable batteries;
  • Strategies to improve the energy density and capacity of flexible and wearable batteries without compromising their flexibility;
  • Enhancing the safety and thermal stability of flexible batteries through advanced materials and structural design;
  • Development of eco-friendly and biocompatible materials for use in wearable or implantable batteries;
  • Innovations in wireless charging, energy harvesting, and power management systems for wearable batteries;
  • Techniques for integrating batteries into wearable electronics, including textiles and medical devices.

The remarkable advantages of zinc anodes render aqueous zinc-ion batteries (ZIBs) a highly promising energy storage solution. Nevertheless, the uncontrolled growth of zinc dendrites and side reactions pose significant obstacles to the practical application of ZIBs. To address these issues, a straightforward strategy has been proposed, involving the addition of a minute quantity of AgNO3 to the electrolyte to stabilize zinc anodes. This additive spontaneously forms a hierarchically porous Ag interphase on the zinc anodes, which is characterized by its zinc-affinitive nature. The interphase offers abundant zinc nucleation sites and accommodation space, leading to uniform zinc plating/stripping and enhanced kinetics of zinc deposition/dissolution. Moreover, the chemically inert Ag interphase effectively curtails side reactions by isolating water molecules. Consequently, the incorporation of AgNO3 enables zinc anodes to undergo cycling for extended periods, such as over 4000 h at a current density of 0.5 mA/cm2 with a capacity of 0.5 mAh/cm2, and for 450 h at 2 mA/cm2 with a capacity of 2 mAh/cm2. Full zinc-ion cells equipped with this additive not only demonstrate increased specific capacities but also exhibit significantly improved cycle stability. This research presents a cost-effective and practical approach for the development of reliable zinc anodes for ZIBs. Full article
