Development of Energy Storage or Conversion Element Based on Various Nano Materials

Dear Colleagues,

Various nanomaterials have led to innovative developments in many fields. In particular, nanomaterials lead us to new paths that we had never imagined before, with the improvement of reactivity and kinetics based on its huge surface to volume ratio, as well as the confinement effects.

These days, nanomaterials are expected to offer new solutions, such as the use of efficient energy based on limited resources. Indeed, these various nanomaterials show various initial results that can surpass the existing performance in the fields of solar cells and secondary batteries. On the other hand, these new materials are creating other challenging problems. For example, the large specific surface areas of nanomaterials can provide a lot of reaction sites in energy conversion or storage and accelerate diffusion and transport properties, but rather lead to more side reactions that can degrade the efficiency of the overall system. Therefore, it is important to maintain the advantages of nanomaterials but minimize the negative effects to enable more efficient energy storage or conversion.

This Special Issue deals with ways to make energy conversion or storage more effective by applying these various nanomaterials. Rather than simply using nanomaterials, we want to actively utilize the various advantages of the nanomaterials, discover new phenomena associated with them, and suppress side reactions to pursue more efficient energy conversion or storage.

In addition, this Special Issue will cover the application of a wide range of nanomaterials for energy conversion or storage. This is not only a solar cell using various nanomaterials such as quantum dots or perovskite nanocrystals, but also active materials for thermoelectrics, lithium-ion secondary batteries, and supercapacitors based on low-dimensional nanomaterials. We also welcome the development of any nanomaterials that can lead to innovations in energy conversion and storage, from those currently attracting attention to hyrovoltaic power generation.

I believe this Special Issue can inspire many ideas in scientists who have been pursuing improved energy conversion or storage based on various nanomaterials.
