To achieve high-value utilization of silicon monoxide tailings (SiO-W), SiO-W@G composite anode materials for Li-ion batteries were prepared by granulating the composite of SiO-W and graphite with pitch as a binder, and their electrochemical performances were then compared with those of conventional SiO@G anode materials. The results show that SiO-W@G, with particle size (D50=11.390 μm), is smaller than SiO@G (16.831 μm) and has larger specific surface area (15.66 m2/g vs. 10.80 m2/g), but both have the same tap density (0.99 g/cm3). SiO-W is uniformly composited with graphite, and there is no obvious difference in crystal structure. Electrochemical tests show that SiO-W@G delivers a specific capacity of 443.55 mAh/g and an initial coulombic efficiency of 85.56%, which are close to those of SiO@G (463.65 mAh/g, 86.39%). It is concluded that the granulation of composite can effectively enable the high-value utilization of silicon monoxide tailings, presenting good prospects for industrial application.

为解决氧化亚硅尾料(SiO-W)高值化利用难题,以沥青为黏结剂,将SiO-W和石墨复合造粒,制备出锂离子电池负极材料——SiO-W@G复合材料,并与常规SiO@G负极材料进行电化学性能对比。结果表明,SiO-W@G的粒径(D50=11.390 μm)小于SiO@G的粒径(16.831 μm),比表面积(15.66 m2/g)大于SiO@G的比表面积(10.80 m2/g),但两者振实密度一致(0.99 g/cm3);SiO-W与石墨实现了均匀复合,且晶体结构无明显差异;电化学性能测试结果表明,SiO-W@G的比容量为443.55 mAh/g,首次库仑效率为85.56%,与SiO@G对应电性能(463.65 mAh/g,86.39%)相近。该复合造粒工艺可有效实现氧化亚硅尾料的高值化利用,具备工业化应用前景。

为解决氧化亚硅尾料(SiO-W)高值化利用难题,以沥青为黏结剂,将SiO-W和石墨复合造粒,制备出锂离子电池负极材料——SiO-W@G复合材料,并与常规SiO@G负极材料进行电化学性能对比。结果表明,SiO-W@G的粒径(D50=11.390 μm)小于SiO@G的粒径(16.831 μm),比表面积(15.66 m2/g)大于SiO@G的比表面积(10.80 m2/g),但两者振实密度一致(0.99 g/cm3);SiO-W与石墨实现了均匀复合,且晶体结构无明显差异;电化学性能测试结果表明,SiO-W@G的比容量为443.55 mAh/g,首次库仑效率为85.56%,与SiO@G对应电性能(463.65 mAh/g,86.39%)相近。该复合造粒工艺可有效实现氧化亚硅尾料的高值化利用,具备工业化应用前景。

To achieve high-value utilization of silicon monoxide tailings (SiO-W), SiO-W@G composite anode materials for Li-ion batteries were prepared by granulating the composite of SiO-W and graphite with pitch as a binder, and their electrochemical performances were then compared with those of conventional SiO@G anode materials. The results show that SiO-W@G, with particle size (D50=11.390 μm), is smaller than SiO@G (16.831 μm) and has larger specific surface area (15.66 m2/g vs. 10.80 m2/g), but both have the same tap density (0.99 g/cm3). SiO-W is uniformly composited with graphite, and there is no obvious difference in crystal structure. Electrochemical tests show that SiO-W@G delivers a specific capacity of 443.55 mAh/g and an initial coulombic efficiency of 85.56%, which are close to those of SiO@G (463.65 mAh/g, 86.39%). It is concluded that the granulation of composite can effectively enable the high-value utilization of silicon monoxide tailings, presenting good prospects for industrial application.
