Abstract ：
The recovery of spent graphite (SG) from lithium-ion batteries (LIBs) has been neglected due to its relatively low value and the lack of effective recovery methods. In this study, a green and cost-effective water washing process was used to recycle the spent graphite of LIBs anode, and the recovered graphite (RG) was used as the cathode material of aluminum ion batteries (AIBs). The RG retained the integrated graphite structure after the water washing process, showing a slightly enlarged interlayer spacing. When used as a cathode material for AIBs, it exhibits better electrochemical performance than commercial artificial graphite. At a current density of 50 mA g−1, the RG shows a high specific capacity of 95.2 mAh g−1. At a high current density of 2000 mA g−1, the specific capacity still maintains 51 mAh g−1, demonstrating excellent rate performance. Meanwhile, the average specific capacity of 72.5 mAh g−1 was steadily cycled for 10,000 cycles at a current density of 1000 mA g−1, showing excellent cycle performance. This work provides a novel approach to the high-value-added application of spent graphite from lithium batteries and a development of high-performance graphite cathode materials for AIBs. © 2024

Abstract ：
Ultrasmall nanoparticle contrast agents provide dual-mode MRI. However, the application of ultrasmall nanoparticle contrast agents is limited by low manufacturing outputs and cumbersome preparation processes. Herein, we report a novel continuous-flow coprecipitation method for the preparation of the Fe3O4 nanoparticles magnetic fluid (CFCPFe) coated with ultrasmall cysteine-terminated polymethacrylic acid (Cys-PMAA). The preparation process is more coherent, simpler, and less expensive. Compared with magnetic fluids prepared by the conventional method (Cys-PMAA@Fe3O4), CFCPFe has smaller particle sizes (3.27 +/- 0.93 nm). Moreover, CFCPFe demonstrates excellent stability for >180 days with different pH values (pH = 2-12) and salt concentrations (up to 2 mol/L). In addition, HEK293T cytotoxicity tests, hemolysis tests, and H&E tissue sections show excellent in vitro and in vivo biocompatibility. In vitro magnetic resonance imaging (MRI) at 1.5 T shows that the r(2) value (50.51 mM(-1).s(-1)) of CFCPFe is slightly lower than that of Combidex (r(2) = 65 mM(-1).s(-1)) and that the r(1) value (9.54 mM(-1).s(-1)) is 2.7 times higher than that of Gd-DTPA (r(1) = 3.5 mM(-1).s(-1)). Finally, in vivo imaging shows that CFCPFe reaches the tumor region of the mouse liver cancer model, and a small tumor can be observed in dual-mode imaging. This work offers an effective method for the preparation of a low-cost, stable, and biocompatible ultrasmall contrast agent exhibiting a strong magnetic-imaging effect for dual-mode imaging.

Abstract ：
The crystalline silicon nanoparticles coated with an amorphous silicon layer was prepared by continuously pyrolysing the mixture of silane and hydrogen in a non-thermal arc plasma reactor. The hydrogen in the gas mixture effectively controls the thickness of the amorphous silicon layer and further improves the electrochemical performance of the silicon anode. The mechanism of the hydrogen was investigated by experiments. At the same time, a three-component polymer binder was concocted and introduced to tolerate the volume expansion of silicon effectively. Combining the silicon nanoparticles prepared at the optimal conditions with the novel polymer binder, the resulting silicon anode exhibits excellent electrochemical performance of 2120 mAh g(-1) at 400 mA g(-1) after 100 cycles.
