Synergistic Electronic and Structural Engineering in an Fe-NiCo2O4@NiFeCo-LDH Core–Shell Heterostructure toward High-Performance Supercapacitors
Nickel-cobalt spinel oxide (NiCo2O4) has attracted extensive research interest as an electrode material for supercapacitors due to its outstanding electrochemical properties; however, its practical performance is often constrained by low intrinsic electrical conductivity, slow ion transport dynamics, and underutilize...
