“…In the reported literature, the black mass recovery and electrochemical activity of electrode materials are restored by acid leaching (H 2 SO 4 -H 2 O 2 , HCl-H 2 O 2 , organic acids, etc. ), NMP, or microwave-assisted deep eutectic solvent based leaching. ,− Herein, we focus on improvising the electrochemical performance of water-leached recovered graphite by using a conductive additive to the recovered graphite matrix instead of any acidic solvent washing, as reported earlier.…”

The ubiquitous manufacturing of lithium-ion batteries (LIBs) due to high consumer demand produces inevitable e-waste that imposes severe environmental and resource sustainability challenges. In this work, the charge storage capability and Li-ion kinetics of the recovered water-leached graphite (WG) anode from spent LIBs are enhanced by using an optimized amount of recycled graphene nanoflakes (GNFs) as an additive. The WG@GNF anode exhibits an initial discharge capacity of 400 mAh g–1 at 0.5C with 88.5% capacity retention over 300 cycles. Besides, it delivers an average discharge capacity of 320 mAh g-1 at 500 mA g–1 over 1000 cycles, which is 1.5–2 times higher than that of WG. The sharp increase in electrochemical performance is due to the synergistic effects of Li-ion intercalation into the graphite layers and Li-ion adsorption into the surface functionalities of GNF. Density functional theory calculations reveal the role of functionalization behind the superior voltage profile of WG@GNF. Besides, the unique morphology of spherical graphite particles trapping into graphene nanoflakes provides mechanical stability over long-term cycling. This work explains an efficient strategy to upgrade the electrochemical compatibility of recovered graphite anode from spent LIBs toward next-generation high-energy-density LIBs.

“…However, the growing demand for LIBs is pushing up the price of raw materials and the existing battery materials cannot satisfy the energy demand. Accordingly, it is urgent to develop renewable, sustainable, and green battery materials to realize sustainable development [7][8][9]. In this regard, natural biomaterials are increasingly attracting interest in green batteries due to the numerous advantages of biopolymers such as broad-resource, low-cost, and environmental protection [10,11].…”

As a key component of lithium‐ion batteries (LIBs), separator plays a crucial role in the performance and safety of LIBs. In this paper, a cellulose‐based porous membrane modified by nano CaCO3 is prepared conveniently by electrospinning. The membrane exhibits rich fibrous porous networks and uniform distribution of nanoparticles. Strengthened by CaCO3, the tensile strength of the cellulose porous membrane elevates from 4.7 ± 0.4 MPa to 7.7 ± 0.7 MPa. Besides, the modified membranes possess improved thermal stability and can maintain their original size after treatment at 150°C and 180°C. Also, the electrolyte uptake of cellulose/CaCO3 membrane is 73% higher than that of the pure cellulose membrane. Thus, the ionic conductivity of membrane achieves 1.08 mS cm−1 and the electrochemical window is about 4.8 V, which meets the practical requirements of LIBs. Significantly, with LiFePO4/Li battery this membrane can run for 230 cycles with a capacity retention of 97.4% and a discharge capacity of 149.0 mAh g−1, demonstrating the huge potential for high safety and next‐generation LIBs.
