Two-dimensional materials, especially the newly emerging MXene, have attracted numerous interests in fields of energy conversion/storage and electromagnetic shielding/absorption. However, inherently inevitable aggregation absence magnetic loss MXene considerably limit its absorption application. The introduction component favorable structural engineering are alternatives to improve microwave (MA) performance. Herein, we report a spheroidization strategy assemble double-shell MXene@Ni microspheres, where commonly lamellar reshaped into three-dimensional microspheres that provide substrate for oriented growth Ni nanospikes. Whereas this feature offers massive accessible active surfaces effectively promote dielectric ability, nanospikes enables additional capacity. Benefiting from these merits, synthesized 3D exhibit superior MA performance with minimum reflection value -59.6 dB at an ultrathin thickness (∼1.5 mm) effective bandwidth 4.48 GHz. Moreover, electron holography results reveal high-density anisotropy magnetism plays important role improvement performance, which provides insight design MXene-based materials as high-efficient absorbers.
