With the continued penetration of the novel high-performance electrochemical energy devices into our daily lives and modern industries, issues including stability, reliability, and safety become critical due to the high-density chemical/electrochemical reactions during energy generation, transport, and storage. Functional nanomaterials have found their way of addressing present challenges with remarkable structural and electronic transformation properties. However, the properties of the materials during the transformation and the role of the surfaces and interfaces for energy transfer are far from being understood.

Therefore, this collection aims to cover exciting new research in the development of functional nanomaterials for energy conversion, energy transmission, energy storage, and broad applications in portable electronics, electric vehicles, and smart grids. This collection will also provide a forum for interdisciplinary discussions spanning from materials synthesis to device engineering. Most recent advances across the emerging energy working systems, including batteries, super-capacitors, fuel-cells, and perovskite solar cells, will be covered. The research in post-lithium-ion technologies like lithium/sodium-metal, lithium/sodium-sulfur, sodium-ion, and solid-state batteries will be of great interest. The submissions for the materials design and synthesis, advanced diagnostics, modeling, and multi-scale simulations that aim for the fundamental study of energy conversion and transport processes are also encouraged.
