Recent Advances in Developing High-Performance Solid-State Lithium Batteries: Interface Engineering

Abstract

To surmount constraints, the increasing demand for electric vehicles and networks necessitates the use of lithium-ion batteries (LIBs) that traditionally use electrolytes that are volatile organic liquids (LEs). Increasing demand for electric networks and automobiles necessitates safer batteries in the presence of more energy. Lithium solid-state batteries (SSBs) have recently gained popularity as alternatives to LEs. However, the interface instability between solid electrolytes (SEs) and electrodes limits the energy density of SSBs. With parasitic reactions and dendrite growth, this culminates in a short cycle life and a dissatisfied coulombic efficiency. Significant advancements have been made in the field of SEs. Nevertheless, substantial challenges still exist that prevent the practical use of SSBs with high energy densities. This review summarizes the most current findings in the study of electrolytes. Basic comprehension of the mechanism, scientific obstacles, and solutions to electrolyte limitations for high-performance SSBs are covered. Numerous strategies for addressing interface issues are analyzed, and as a result, some recommendations are made regarding the optimal electrolyte characteristics for practical applications. At the end of this review, key concerns and proposals for future study into how best to develop high-performance lithium SSBs are discussed.

Review and Perspectives on Preparation Strategies and Applications of Ti3C2 MXene for Li Metal Batteries/Li–S Batteries

“…These include large-scale energy storage systems, electric vehicles, portable electronic devices, and more. Undoubtedly, this trajectory necessitates a redirection of researchers’ focus toward the realm of new energy, with the primary objective being the development of energy storage materials that are not only safe and reliable but also cost-effective. − Presently, the imperative to address range limitations in electric vehicles and portable electronic devices has elevated the development of high-energy-density rechargeable batteries. − Among all the possible candidates, the intriguing advantages of metallic Li, characterized by the lowest redox potential [−3.04 V versus the standard hydrogen electrode (SHE)] and the highest gravimetric theoretical capacity, position it as the coveted “Holy Grail” anode. , Consequently, researchers have shifted their focus to high-performing lithium metal batteries, although challenges persist due to uncontrollable dendrite formation, volume change and an unstable interface between the anode and liquid electrolyte, hindering the practical application of lithium metal batteries. ,− In recent years, researchers have thoroughly studied the microscopic changes during battery operation and verified the substantive morphology of these problems by using relevant characterization. − Here we have drawn relevant morphological images (Figure ) for readers to understand and recognize. As schematically illustrated in Figure , how to solve the volumetric expansion of lithium metal during charge and discharge cycles, the uncontrolled growth of lithium dendrites, and the instability of the solid electrolyte interface (SEI) film is crucial for the development of lithium metal batteries, so the application potential of the lithium metal anode is substantial .…”
