Here, we report a simple strategy to grow NiSe architectures vertically on nickel foam (NF) via facilesolution-based deposition. The as-synthesized NSE7h core-shell nanoplate structure with a mass loadingof 6.4 mg/cm 2 can be delivered a high specific capacitance of 2234.84 Fg 1 at 10 mA cm 2 andoutstanding rate capability compared to that of NO (708.52 Fg 1), NS (968.22 Fg 1), NSE1h (1357.43 Fg 1),and NSE4h (1675.87 Fg 1). The desirable electrochemical performance was mainly attributed to thecomponent’s synergy assuring rich redox reactions, deposition of selenium on the surface of NiOnanotubes, high conductivity, great specific area and furthermore, rapid ion diffusion distance, witheffective transport pathway of electrons and electrolyte ions. The existence of selenium vacancies andversatile synthesis of NiSe architectures would open up a wide range of applications in energy storageand conversion applications including supercapacitors, electrocatalysis, and batteries.
