About this Research Topic
The realization of a sustainable decarbonized economy requires the widespread use of renewable energy sources. Advanced energy storage technologies such as hydrogen storage, rechargeable batteries, thermal energy storage, etc. are greatly needed due to the fluctuating nature of solar and wind energy sources and the acceptance limit of current power grids. Under such circumstances, the development of advanced materials with large energy capacity, high energy density, and high safety has taken center stage in multiple fields of chemistry, physics, and materials science. Hydrides with high potential for various energy applications like hydrogen storage, rechargeable batteries, thermal storage, and superconductors, are one of the main focuses in the development of energy materials.
Solid-state hydrides have been seen largely as potential hydrogen storage materials due to the high volumetric density and safety, which is needed for the feasibility of a hydrogen economy. Tremendous efforts have been devoted to developing hydrogen storage materials with high gravimetric and volumetric densities, and some important progress has been achieved recently. In addition, hydrides have been attracting more interest due to the other functions relevant to energy applications, such as superionic conductors, battery electrode materials, thermal storage, superconductors, and so on. This Research Topic is dedicated to showcasing the state-of-the-art in hydrides and discussing their key factors including thermodynamics, kinetics, crystal structure, defects, and interfaces, which may determine the abovementioned functions.
The scope of this Research Topic will focus on metal hydride-based energy storage and conversion materials, including, but not limited to:
• hydrogen storage
• rechargeable batteries
• superionic conductivity
• thermal storage
Reviews and original research articles are all welcome.
