Utilization of the nickel hydroxide derived from a spent electroless nickel plating bath for energy storage applications

Abstract

In this study, a simple one-step approach has been proposed to treat spent electroless nickel plating bath by precipitating nickel metal as nickel hydroxide. Beta phase nickel hydroxide β-Ni(OH)2 generated...

Repurposing Mining and Metallurgical Waste as Electroactive Materials for Advanced Energy Applications: Advances and Perspectives

“…Transition metal-based layered double hydroxides (LDHs) synthesized from electroplating sludge have been used for supercapacitors [31,71]. The β-Ni(OH) 2 powder prepared from a spent electroless nickel plating bath has a high specific capacitance of 332 F•g −1 at 5 mV•s −1 , mainly due to the pseudocapacitance property of β-Ni(OH) 2 [31].…”

For the NiFeAl LDHs hydrothermally synthesized from electroplating sludge, the utilization of urea in the synthesis process leads to decreased particle size and large SSA [71].…”
