The liquid electrolyte for a secondary battery according to the present invention comprises: a solvent; an electrolyte salt; and anisotropic magnetic particles. The anisotropic magnetic particles contained in the liquid electrolyte are dispersed in the liquid medium of the liquid electrolyte, and through the application of an external magnetic field, rotation of the anisotropic magnetic particles can be generated and micro-convection and a dynamic state of the internal electrolyte can be induced. Accordingly, the formation of metal dendrites can be suppressed. https://scholar.dgist.ac.kr/handle/20.500.11750/58788 https://scholar.dgist.ac.kr/handle/20.500.11750/58778 Title: Positive electrode slurry for lithium secondary battery, method for preparing same, positive electrode for lithium secondary battery, and lithium secondary battery Author(s): 반성호; 이준기; 이홍경; 김고은; 이윤성; 이현태 Abstract: The invention discloses a positive electrode slurry for a lithium secondary battery, a preparation method thereof, a positive electrode for a lithium secondary battery, and a lithium secondary battery, and particularly discloses a positive electrode slurry containing a reduced content of a binder, a method of preparing the positive electrode slurry, a positive electrode prepared from the slurry, and a lithium secondary battery including the positive electrode. https://scholar.dgist.ac.kr/handle/20.500.11750/58778 https://scholar.dgist.ac.kr/handle/20.500.11750/58741 Title: METHOD FOR PREPARING LITHIUM METAL NEGATIVE ELECTRODE FROM WHICH SURFACE OXIDE LAYER IS REMOVED, AND LITHIUM METAL NEGATIVE ELECTRODE PREPARED THEREBY Author(s): 임민홍; 박상현; 김범준; 서지연; 이지원; 최보경; 이홍경 Abstract: The present invention relates to a method for preparing a lithium metal negative electrode from which a surface oxide layer is removed by physically removing the surface oxide layer formed on the surface of lithium metal by using a cutting tool, and to a lithium metal negative electrode prepared by the method. According to the present invention, since there is no surface oxide layer causing non-uniformity of the surface of the lithium metal negative electrode, overvoltage is reduced at the interface between the negative electrode and an electrolyte, thereby enabling rapid and uniform transport. It is possible to inhibit dendritic growth on the surface of the negative electrode as a nucleus is not locally formed, and a generally flat and uniform electrodeposition shape is exhibited. In addition, the number of cycles is increased, and the formation of a lithium porous layer and dead lithium, which are factors degrading the performance of a lithium metal battery, is reduced, thereby improving cycle performance. https://scholar.dgist.ac.kr/handle/20.500.11750/58741
