Electrode materials for Li/Na storage from mechanochemically synthesised MOFs/MXene Composites: A Solvent-free approach

The development of new energy-related materials is the pinnacle to attaining a sustainable society based on renewable energy. Over the past decades, plenty of electrode materials have been investigated seeking better energy storage properties. However, the often-tedious synthetic procedures and large amounts of solvents utilised during their syntheses incur high costs and severe environmental pollution. Here we present a solvent-free approach to metal–organic-frameworks/MXene-derived carbonaceous metal selenide/MXene composites with unique nanostructures rich in mesopores and macropores. These species can be readily transformed into high-performance electrode materials with enhanced Li/Na ion storage properties compared with their solution-based counterparts. Herein we report not only a unique metal–organic framework/MXene-derived electrode material displaying high-performance for advanced lithium/sodium storage applications but also its novel environmentally benign production process.
