“…Furthermore, a depth-dependent distribution is found in Li concentration. The present work on degradation mechanism in a full device is a continuation of earlier studies of ours [16][17][18][19] showing enhanced EC performance such as enlarged optical contrast, fast switching response and improved durability, WO 3 -1 and NiO-1 (from ECD1); WO 3 -2 and NiO-2 (from ECD2); and WO 3 -3 and NiO-3 (from ECD3), respectively.…”

“…In addition, the peak fitting of XPS analysis exhibited several peaks at the binding energy of: ∼778.3 eV (metallic Co), ∼780.5 eV (CoOOH), and ∼782.0 eV (Co(OH) 2 ) in the Co 2 p 3/2 spectrum and ~852.5 eV (metallic Ni), ~855.6 eV (Ni(OH) 2 ), and ~856.5 eV (Ni 2 O 3 ) in the Ni 2 p 3/2 spectrum (Supplementary Fig. 13 ) 54 – 57 . These peaks indicated the formation of oxide/hydroxides, including metallic species, probably due to surface oxidation and/or hydroxide formation during electrodeposition, which in part agreed with EQCM analysis (Eqs.…”

Selective cobalt and nickel electrodeposition for lithium-ion battery recycling through integrated electrolyte and interface control

et al. 2021

Molecularly-selective metal separations are key to sustainable recycling of Li-ion battery electrodes. However, metals with close reduction potentials present a fundamental challenge for selective electrodeposition, especially for critical elements such as cobalt and nickel. Here, we demonstrate the synergistic combination of electrolyte control and interfacial design to achieve molecular selectivity for cobalt and nickel during potential-dependent electrodeposition. Concentrated chloride allows for the speciation control via distinct formation of anionic cobalt chloride complex (CoCl42-), while maintaining nickel in the cationic form ([Ni(H2O)5Cl]+). Furthermore, functionalizing electrodes with a positively charged polyelectrolyte (i.e., poly(diallyldimethylammonium) chloride) changes the mobility of CoCl42- by electrostatic stabilization, which tunes cobalt selectivity depending on the polyelectrolyte loading. This strategy is applied for the multicomponent metal recovery from commercially-sourced lithium nickel manganese cobalt oxide electrodes. We report a final purity of 96.4 ± 3.1% and 94.1 ± 2.3% for cobalt and nickel, respectively. Based on a technoeconomic analysis, we identify the limiting costs arising from the background electrolyte, and provide a promising outlook of selective electrodeposition as an efficient separation approach for battery recycling.

Electrochemical behavior of spray deposited nickel oxide (NiO) thin film in Alkaline electrolyte

et al. 2022

Nickel oxide (NiO) Thin film was successfully deposited on the glass substrate using an inexpensive spray pyrolysis (SP) technique. The structural, morphological, and optical properties have been studied, thus the electrochemical behavior of NiO film in Alkaline electrolytes has been investigated. The X-ray diffraction (XRD) analysis showed that NiO thin film exhibit a polycrystalline cubic rock-salt structure with a preferential orientation on the plane (111). This result was confirmed using Raman spectroscopy. The Scanning Electron Microscopy (SEM) images exhibit a smooth and dense surface without major cracks. Optical analysis shows an average transmission of about 55% in the visible light range, and the optical band gap energy was estimated by Tauc’s method and showed a value of 3,71 eV. Electrochemical properties as specific capacitance (Csp), optical density variation (ΔOD), and Coloration efficiency (CE) were studied using cyclic voltammetry in 1M KOH and 1M NaOH electrolytes. The results indicated that the behavior of the NiO layer in KOH is more effective than in NaOH electrolytes.
