The Cover Feature illustrates the chemical coupling of heterostructured Fe 2 O 3 –Fe 3 O 4 nanoparticles with graphene and its supercapacitive performance. The amorphous Fe 3 O 4 coating on the crystalline Fe 2 O 3 phase as well as the chemical coupling enhance the charge‐storage capability and cycling stability of the hybrid material.
