The dissolution process encompasses an organic acid leaching followed by recovery of pure Co oxalate. The use of lactic acid effectively improves the leaching of spent LiCoO2 materials with ascorbic acid. The leaching efficiencies of 99% for Li and 98% for Co were achieved under the optimal condition of 0.5 mol/L lactic acid and 0.02 mol/L ascorbic acid, solid/liquid ratio of 2 g/L, leaching time of 360 min and temperature of 90 °C. Based on the kinetic analysis, the enhancement leaching process is mainly on the concentration of dissolution reagent. Compared to other organic acids used previously, lactic acid showed better dissolution behavior.</style></abstract><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">3.504</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Rawat, Purnima</style></author><author><style face="normal" font="default" size="100%">Shivamurthy, B.

	Spent lithium-ion batteries (S-LIBs) are typically discarded in landfills after their lifecycle ends, despite containing valuable materials like graphite. While much research focuses on extracting precious metals from the cathode, this study explores the recycling, recovery, and reuse of spent graphite, converting it into reduced graphene oxide (rGO) for electrochemical sensing. The rGO material demonstrated excellent sensitivity to ascorbic acid (AA) in a concentration range of 1 mM to 100 mM at pH 7.6, offering a cost-effective solution for AA detection. The recovered graphite (RG) from S-LIBs and commercial graphite (CG) was first converted into graphene oxide (R-GO, C-GO) and then reduced (R-rGO, C-rGO). This material underwent extensive structural characterization using techniques such as powder X-ray diffraction (PXRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) analysis, field-emission scanning electron microscopy (FE-SEM), and high-resolution transmission electron microscopy (HR-TEM). Electrochemical performance was evaluated through cyclic voltammetry (CV), differential pulse voltammetry (DPV). This study underscores the ``waste-to-wealth'' concept and supports circular economy principles by transforming electronic waste into a valuable resource. The LOD and LOQ for both the material R-rGO and C-rGO were calculated as 3.055 mM, 10.18 mM, and 3.41 mM, 11.36 mM, respectively. The rGO-based sensor not only promotes sustainable recycling but also offers a low-cost, high-performance solution for ascorbic acid detection, with potential applications in food quality monitoring, medical diagnostics, and the cosmetic industry.&lt;/p&gt;
