MXene:Promising materials for magnesium-ion batteries

Magnesium-ion batteries(MIBs)have attracted extensive attention due to their high theoretical capacity,superior safety,and low cost.Nonetheless,the development of MIBs is hindered by the lack of cathode materials with long cycle life and rate capability.MXene stands out as a prime choice for MIB cathode or collector for anode-free magnesium batteries(AFMBs)because of its larger surface area,adjustable surface properties,and good electrical conductivity.In this paper,we summarized the preparation and layering methods of MXene and discussed the prospects of MXene as a cathode or collector for MIBs.This review will be immensely beneficial in critically analyzing the synthesis techniques and the applications of MXene material as MIB cathode or AFMB collector.In addition,the challenges of the preparation and layering were concluded,along with raising the research strategies of MXene for storing Mg ions.
