The construction of a 2D MoS2-based binder-free electrode with a honeycomb structure for enhanced electrochemical performance

Abstract

MoS₂ with a two-dimensional morphology has been recognized as a promising electrode material due to its good electrochemical activity. An integrated electrode has been achieved by growing MoS₂ on nickel foam with a nanosheet morphology and honeycomb structure. This binder-free MoS₂/Ni₃S₂/NF electrode has demonstrated a specific capacity of 300.26 mA h g⁻¹ (0.61 mA h cm⁻²) at 1 A g⁻¹ with 73.8% retention at 20 A g⁻¹, while maintaining good electrochemical stability during 4000 charging–discharging cycles.
