Interfacial Electronic Coupling of 2D MXene Heterostructures: Cross-Domain Mechanistic Insights for Solid-State Lithium Metal Batteries

Humanity faces systemic challenges in key areas such as energy security and climate governance, so its crucial to develop and use clean energy. And the solid-state lithium battery shows great potential as an energy resource. However, the solid-state lithium battery has some deadly defects, like low efficiency and so on. This article mainly studies the interfacial electronic coupling effect that exists in the two-dimensional MXene heterostructures (mentioned as 2D MXene heterostructures in the following paragraphs) and their coordinative mechanism. So, the thesis aims to find the principle of the electronic coupling effect and the improvement that 2D MXene could make in the properties of solid-state lithium metal batteries. This paper mainly conducts the research by using the document analysis method. The result of the research shows that not only does the electron coupling effect occur at the MXene material and its heterostructures, but this phenomenon also helps to improve the properties of the battery.
