About this Research Topic
With the rapid development of sustainable and renewable energy sources, electrochemical energy conversion and storage has attracted more and more attention in recent years. Various promising electrochemical systems have been continuously investigated and developed to meet the demands for high-efficiency energy conversion. In these systems, both the mechanical and electrical properties are the dominating factors in the overall battery and catalysis performance, and the structures and dimensions of active materials in these systems are determining parameters as well.
Firstly, nanomaterials and nanocomposites have attracted tremendous attention since they possess many fascinating physicochemical properties compared to the bulk materials. They can be classified as one dimensional (1D) materials such as nanorods and nanowires, two dimensional (2D) materials like nanosheets and nanoplates, and three dimensional (3D) materials such as nanospheres, nanocubes. Both the 3D and 2D nanocomposites have shown many unique advanced properties combining large specific surface area, high mechanical strength, and multi-direction ion/electron transport.
Secondly, at the atomic and molecular levels, it is very important to build up the multi-dimensional (2D and 3D) crystal structures since high ionic/electronic conductivities are mainly based on the multi-direction transport/diffusion pathways. Besides, the multi-dimensional materials can provide much better surface contact between the solid-solid, solid-liquid, and solid-gas interfaces, which are critical for the superior interface transfer kinetics and high-efficiency mass transport and electron transfer. Strenuous efforts have been pursued to amplify these benefits, including structural confinement design, multifunctional materials fabrications, and interlayer configurations in various types of energy storage and conversion systems. Additionally, for large-scale fabrications, the multi-dimensional structures are ideal substrate configurations to achieve high loading amount of active materials with satisfactory flexibility and stretchability.
Therefore, the purpose of this Research Topic is to better understand multi-dimensional energy materials and relevant electrochemical behaviors in the various electrochemical energy conversion and storage systems (including both cathode and anode materials, fabrication/design strategies, and electrolyte materials). Intensive research of these promising materials contributes to expanding our comprehensive understanding of multi-dimensional materials at various scales and application scenarios.
