Abstract

Abstract Multifunctional applications including efficient microwave absorption and electromagnetic interference (EMI) shielding as well as excellent Li‐ion storage are rarely achieved in a single material. Herein, a multifunctional nanocrystalline‐assembled porous hierarchical NiO@NiFe 2 O 4 /reduced graphene oxide (rGO) heterostructure integrating microwave absorption, EMI shielding, and Li‐ion storage functions is fabricated and tailored to develop high‐performance energy conversion and storage devices. Owing to its structural and compositional advantages, the optimized NiO@NiFe 2 O 4 /15rGO achieves a minimum reflection loss of −55 dB with a matching thickness of 2.3 mm, and the effective absorption…
