Special Issue Information

Dear Colleagues,

The continuous pursuit of better human life promotes the ceaseless advances of intelligent community. Flexible batteries have emerged as a brand new form to compensate or even replace traditional rigid-materials-based energy storage. Owing to their distinct merits in terms of ductility, stretchability, ultrathinness etc., flexible batteries can be seamlessly mounted onto the human skin or other complex object surfaces, which unprecedentedly bridges our human body, environment and machines. They have presented diverse intriguing applications in healthcare, human–machine–environment interfaces, energies, intelligent robots, Internet of Things etc. Therefore, they have been considered next-generation smart electronics.

There are a variety of categories of flexible batteries, such as batteries, supercapacitors, and solar cells. In principle, two strategies are employed to construct flexible batteries, including materials innovation and structural design. In particular, functional nanomaterials are considered indispensable parts of flexible batteries. The past decade has witnessed the development of various functional nanomaterials, mainly including nanoparticles, nanowires, nanosheets and nanoporous materials.

Therefore, the development of functional nanomaterials is of high significance for practical applications of flexible batteries. The purpose of this Special Issue is to present the latest state-of-the-art research progress on emerging nanomaterials for flexible batteries as well as research trends and application prospects. Potential topics include, but are not limited to, the following:

  • Nanoparticles on flexible batteries;
  • Nanowires on flexible batteries;
  •  Nanosheets on flexible batteries;
  • Nanoporous materials on flexible batteries;
  • Hydrogels on flexible batteries;
  • Liquid metal on flexible batteries;
  • Polymers on flexible batteries;
  • Composites on flexible batteries.

Related applications include (but are not limited to):

  • Wearable energy storage;
  • Flexible supercapacitors;
  • Flexible solar cells.

Traditional lithium-ion batteries cannot meet the high flexibility and bendability requirements of modern flexible electronic devices due to the limitations of the electrode material. Therefore, the development of high-performance flexible energy storage devices is of great significance for promoting flexible electronics. In recent years, one-dimensional flexible fiber lithium-ion batteries have been rapidly developed due to their advantages of high flexibility and bendability. However, it remains highly challenging to realize 1D flexible fiber lithium-ion batteries with excellent electrochemical properties and good mechanical performance. In this work, a reduced graphene oxide-based printing ink is proposed for the fabrication of flexible Li4Ti5O12/graphene fiber electrodes using a 3D printing assembly strategy. It is noteworthy that the green reducing agent vitamin C was used to reduce the graphene oxide in one step, which improved the conductivity of the fiber electrode. Furthermore, a 3D conductive network was constructed inside the fiber electrodes due to the high specific surface area of the reduced graphene oxide, which enhanced the electronic conductivity and ion mobility. The fiber electrode not only exhibits good mechanical performance, but also has excellent electrochemical properties. Equally importantly, the method is simple and efficient, and the working environment is flexible. It can precisely control the shape, size and structure of the one-dimensional fiber flexible electrode, which is of great significance for the development of future flexible electronic devices.
