摘要： Rechargeable batteries, which are used for renewable energy storage, have paved the way for reducing the enormous pressure of the energy crisis and environmental pollution. Recently, promising electrode materials with high energy and power density and favorable electrochemical performance for energy conversion and storage have been developed to meet the ever-growing demand for renewable power for electric vehicles or grid applications. MXenes, which constitute an impressive two-dimensional transition metal carbide/carbonitride family, exhibit great energy storage potential based on their ideal specific surface area, excellent electrical conductivity, and superior chemical durability in batteries. The recent advances in MXenes and their composites for metal-sulfur batteries (specifically lithium-sulfur and sodium-sulfur batteries) and metal-air batteries (specifically lithium-air and zinc-air batteries) are comprehensively and systematically summarized in this review. Furthermore, the performance management strategies, next-stage research prospects, and remaining practical challenges for MXene-based materials in battery applications are discussed in detail. This review may provide some guidance for the development and application of MXene-based electrode materials in renewable electrochemical energy storage.
