Fabrication of Nickel Nanosized Powder from LiNiO2 from Spent Lithium-Ion Battery

Abstract

Abstract:In this study, a fabrication of nickel nanoparticles from LNO(LiNiO 2 ), which is a cathode active material, was synthesized by the liquid reduction process of NiSO 4 , obtained through a leaching and purification process. Hydrazine monohydrate (N 2 H 4 ·H 2 O) was used as a liquid reducing agent and it was added to NiSO 4 at a volume ratio of NiSO 4 :N 2 H 4 ·H 2 O = 10:3 and reacted for 10 min to synthesize the nickel hydrazine complex. Sodium hydroxide was added to the nickel hydrazine complex at the weight ratio of NiSO 4 :NaOH = 10:1.25-1.5 and the reduction reaction was performed at 80 • C for 15 min to synthesize nickel particles. Synthesized nickel particles were agglomerated and had a mean size of 200 nm to 300 nm. Ultrasonic dispersion, which is a physical dispersion method, was conducted. The nickel had particles of 100 nm or less when dispersed for 2 h at an ultrasonic intensity of 40 kHz. In order to prevent the agglomeration of the dispersed particles again, polyvinylpyrrolidone (PVP), an interfacial stabilizer, was added to stabilize the dispersed particles. It was confirmed that the nanoparticles were stably retained when PVP was added in an amount of 1 to 2 wt % based on the weight of the nickel. The purity of nickel recovered was found to be 99.62 wt %.

Valuable Metal Recycling

“…The preparation of petroleum liquid catalyst [11], Sn-incorporated LiNi x Co y Mn z (NCM) [12], Ni nanosized powder [13] was investigated using leach liquor of a lithium ion battery (LIB). Joo et al [11] introduced a comprehensive recycling process, which included physical separation, leaching, solvent extraction and stripping, to prepare CMB (cobalt-manganese-bromide) and CMA (cobalt-manganese-acetate) liquid catalysts as petroleum liquid catalysts from the cathode materials of spent lithium ion batteries.…”

“…Kang et al [12] investigated the effect of Sn impurity on the LIB performance of Ni-rich NCM, resynthesized from leach liquor of spent LIB by conducting analyses such as scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) mapping, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Shin et al [13] investigated the fabrication of Ni nanosized powder from cathode active material, such as LiNiO 2 (LNO), as found in spent lithium ion batteries through a reduction with hydrazine monohydrate.…”

Fabrication of nano battery from CdS quantum dots and organic polymer

“…Lithium-ion (Li-ion) batteries have become critical for a variety of applications from portable electronics to electric vehicles because of their relatively high energy density, power density, and long cycle life. However, graphene is rarely used for battery electrodes because of its low density and high specific surface area, which result in low initial coulombic efficiency and TPD polymer as acceptor units to investigate the effects of the structure on the optical and electrochemical properties (Wei, X., et al, 2017;Shin, S., et al, 2018). Electronic conductivity, suitable lithium absorption, and electrochemical power, cadmium sulfide quantum dots (CdS QDs) are certainly attractive to CdSNB applications.…”

“…The nanostructures achieved by including graphite in Li-arranging mixtures, e.g., matchless electrode materials, have been enhanced to increase the said striking properties of CdS QDs. The Li is used in electrodes due to its high dedicated surface area between mechanical and transport properties (Shin, S., et al, 2018).…”
