The high content of aluminum(Al)impurity in the recycled cathode powder seriously affects the extraction efficiency of Nickel,Cobalt,Manganese,and lithium resources and the actual commercial value of recycled materials,so Al removal is crucially important to conform to the industrial standard of spent li-ion battery cathode *** this work,we systematically investigated the leaching process and optimum conditions associated with Al removal from the cathode powder materials collected in a wet cathode-powder peeling and recycling production line of spent li-ion batteries(liBs).Moreover,we specifically studied the leaching of fluorine(F)synergistically happened along with the removal process of Al,which was not concerned about in other studies,but one of the key factors affecting pollution prevention in the recovery *** mechanism of the whole process including the leaching of Al and F from the cathode powder was indicated by using NMR,FTIR,and XPS,and a defluoridation process was preliminarily investigated in this *** leaching kinetics of Al could be successfully described by the shrinking core model,controlled by the diffusion process and the activation energy was 11.14 kJ/***,the leaching of F was attributed to the dissolution of liPF6and decomposition of PVDF,and the kinetics associated was described by Avrami *** interaction of Al and F is advantageous to realize the defluoridation to some *** is expected that our investigation will provide theoretical support for the large-scale recycling of spent liBs.

国家监察体制改革后,检察提前介入监察系监检衔接的重要机制。该项机制在实践中存在着种种难点,其完善需以理论上正当依据的确定为基础。对此,通过评析“监察制约”“监察协助”两大阵营下既有观点的理论“资产”和“负债”,检察提前介入监察的应然面貌得以呈现,其能够承载的重要价值与监察法“互相配合,互相制约”的法律原则相契合。由此,制约配合说得以被提出、证立。该说的内容为,通过发挥法律原则的“法律之窗”功能,检察提前介入监察可以凭借其人权保障、社会公正两大价值成为“被规定的”和“有效力的”。制约配合说足以回应检察提前介入监察面临的质疑,其不会与监察独立原则相冲突,亦为化解“联合办案”风险提供了启示。
