Galvanic leaching recycling of spent lithium-ion batteries via low entropy-increasing strategy.

The recycling of spent lithium-ion batteries can effectively mitigate the environmental and resource challenges arising from the escalating generation of battery waste and the soaring demand for battery metals. The existing mixing-then-separating recycling process is confronted with high entropy-increasing procedures, including crushing and leaching, which result in irreversible entropy production due to the decrease in material orderliness or heavy chemical consumption, thereby hindering its thermodynamic efficiency and economic viability of the entire recycling process. Herein, we propose a galvanic leaching strategy that leverages the self-assembly of LiNiCoMnO particles with their inherent aluminium foil current collectors in spent lithium-ion batteries, creating a primary cell system capable of recovering battery metals without pre-crushing or additional reductants.

Mechanochemical upcycling of spent LiCoO to new LiNiCoAlO battery: An atom economy strategy.

The use of strong acids and low atom efficiency in conventional hydrometallurgical recycling of spent lithium-ion batteries (LIBs) results in significant secondary wastes and CO emissions. Herein, we utilize the waste metal current collectors in spent LIBs to promote atom economy and reduce chemicals consumption in a conversion process of spent LiCoO (LCO) → new LiNiCoAlO (NCA) cathode. Mechanochemical activation is employed to achieve moderate valence reduction of transition metal oxides (Co→Co) and efficient oxidation of current collector fragments (Al→Al, Cu→Cu), and then due to stored internal energy from ball-milling, the leaching rates of Li, Co, Al, and Cu in the ≤4 mm crushed products uniformly approach 100% with just weak acetic acid.

Challenges in Recycling Spent Lithium-Ion Batteries: Spotlight on Polyvinylidene Fluoride Removal.

In the recycling of retired lithium-ion batteries (LIBs), the cathode materials containing valuable metals should be first separated from the current collector aluminum foil to decrease the difficulty and complexity in the subsequent metal extraction. However, strong the binding force of organic binder polyvinylidene fluoride (PVDF) prevents effective separation of cathode materials and Al foil, thus affecting metal recycling. This paper reviews the composition, property, function, and binding mechanism of PVDF, and elaborates on the separation technologies of cathode material and Al foil (e.

Interleukin-37 promotes DMBA/TPA skin cancer through SIGIRR-mediated inhibition of glycolysis in CD103DC cells.

Interleukin 37 (IL-37), a member of the IL-1 family, is considered a suppressor of innate and adaptive immunity and, hence is a regulator of tumor immunity. However, the specific molecular mechanism and role of IL-37 in skin cancer remain unclear. Here, we report that IL-37b-transgenic mice (IL-37tg) treated with the carcinogenic 7,12-dimethylbenzoanthracene (DMBA)/12-o-tetradecylphorbol-13-acetate (TPA) exhibited enhanced skin cancer and increased tumor burden in the skin by inhibiting the function of CD103 dendritic cells (DCs).

WFDC12-overexpressing contributes to the development of atopic dermatitis via accelerating ALOX12/15 metabolism and PAF accumulation.

Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by eczema-like skin lesions, dry skin, severe itching, and recurrent recurrence. The whey acidic protein four-disulfide core domain gene WFDC12 is highly expressed in skin tissue and up-regulated in the skin lesions of AD patients, but its role and relevant mechanism in AD pathogenesis have not been studied yet. In this study, we found that the expression of WFDC12 was closely related to clinical symptoms of AD and the severity of AD-like lesions induced by DNFB in transgenic mice.
