Abstract
The rational design of anode materials plays a significant factor in harnessing energy storage. With an in‐depth insight into the relationships and mechanisms that underlie the charge and discharge process of two‐dimensional (2D) anode materials. The efficiency of rechargeable batteries has significantly been improved through the implementation of defect chemistry on anode materials. This mini review highlights the recent progress achieved in defect chemistry on 2D materials for advanced rechargeable battery electrodes, including vacancies, chemical functionalization, grain boundary, Stone Wales defects, holes and cracks, folding and wrinkling, layered von der Waals (vdW) heterostructure in 2D materials. The defect chemistry on 2D materials provides numerous features such as a more active adsorption sites, great adsorption energy, better ions‐diffusion and therefore higher ion storage, which enhances the efficiency of the battery electrode.
Highlights
Owing to the widespread consumption of fossil fuels, the two main global challenges facing the world nowadays consist of environmental-pollution and energy issues
Many defect chemistry models in the framework of 2D materials have a considerable potential to significantly enhance the functionality of 2D materials over a range of energy storage technologies, metal-ion batteries, the amount of published papers or-reviews devoted to different defect chemistry on 2D materials is growing steadily
The 2D-defect chemistry that is typical for von der Waals (vdW) and inter-layer materials, including holes-craks, folding-wrinkling, ripping, and vdW-heterostructure, can occur in 2D materials, these will not be covered in this mini-review, a few defect type related in interlayer materials are significant and will be outlined shortly
Summary
Owing to the widespread consumption of fossil fuels, the two main global challenges facing the world nowadays consist of environmental-pollution and energy issues.
