About this Research Topic
Electrochemical conversion systems have recently been attracting attention as a next-generation clean power source for many applications in the field of alternative energy. These electrical systems have been continuously attempting to overcome the obstacle of limited capacity for utilization in real life applications, such as cell phones, cars, houses and uninterruptible power supply. In these systems, mechanical and electrical properties are key factors in the overall battery performance.
Firstly, nanomaterials and nanocomposites have attracted tremendous attention due to their properties allowing for improved battery performance. They are classified as three dimensional (3D) materials such as metal nano-sphere, nano-cube and nano-star as well as two dimensional (2D) materials such as molybdenum sulfide and 2D manganese oxide families. Recently, many researchers are focusing on one dimensional (1D) nanomaterials (quantum dot materials) as well as inorganic-organic nanocomposite materials (metal-organic framework – MOF) for applications as energy materials to improve electrochemical performance.
Secondly, carbonaceous materials are one of the promising materials to secure the outstanding performance in alternative energy sources. Unique properties of the carbons, such as electrical conductivities, stability, and diverse utilization, allow for the continuous development of the regeneration energy technologies. The carbon families - activated carbons, porous carbons, network carbons, graphene, carbon nanotubes, carbon nanofibers, etc. – are the outstanding candidates in this application. These carbons act as the supporter to anchor the nano-/micro-particles and the porter to facilitate the transport of electrons after the electrochemical reaction as well as the contributor to keep durability in the electrochemical cell. These abilities are affected by 1) the basic properties such as surface area, pore size distribution, the cumulative pore volume of carbon unit, 2) the atom structures – amorphous and graphitic properties, and 3) the degree of s-p hybridization.
The purpose of the present Research Topic is to understand the concept of energy materials and the electrochemical behavior in the battery system (including cathode materials, anode materials, and electrolyte materials), the characterization of their chemical, compositional, functional and structural properties, as well as their electrochemical performance in the energy conversion devices. Intensive research of these materials has been performed to expand our understanding of the relationship between materials and electrochemical performance. Understanding the reaction on the interfacial boundary of energy materials plays a critical role in securing new opportunities to open new generations.
