Abstract

Sodium batteries are the most potential candidates for future and green energies storage systems. However, there are problems with structural instability in the electrodes, which affect battery performance. Therefore, this study investigated the adsorption and diffusion mechanisms at the anode using a phase puckered Germanium Telluride (GeTe) monolayer structure. Density functional theory (DFT) calculations show that the Na-adsorbed hollow Te-Te structure is the most stable adsorption configuration (-1.25 eV). In the diffusion scheme, Na atoms move through the hollow Te-Te (initial state) followed by the hollow Ge-Ge (transition state), then to the hollow Te-Te (final state). The diffusion mechanism that occurs has lowest energy of 0.09 × 10-4 eV. These results suggest that the phase puckered GeTe monolayer has the potential as a high-performance sodium battery anode.

Abstract

Metamaterials have shown great potential for energy device applications, including energy harvesting, storage, and transmission. However, implementing metamaterials in energy devices presents several challenges, such as complex design and fabrication, narrowband limitation, and integration with existing technologies. Despite these challenges, ongoing research and development in the field of metamaterials is focused on exploring new materials, designs, and applications for metamaterials in energy devices. Specific examples of energy devices that use metamaterials include solar cells, wind turbines, thermal management systems, energy storage systems, wireless power transfer systems, and 3D metamaterials for energy harvesting. The use of metamaterials in energy devices has the potential to revolutionize the energy sector by enabling more efficient and sustainable energy generation, storage, and transmission systems.
