  • Publication number: 20200075928
    Abstract: A method for manufacturing a lithium secondary battery including a pre-lithiated negative electrode. A composite of lithium and a negative electrode active material is formed through a lamination process which is a process of manufacturing a battery. In the case of the lithium secondary battery to which the negative electrode having the composite formed by lithium and the negative electrode active material is applied, when the battery starts to operate, the negative electrode active material is pre-lithiated, and thus the charging/discharging process proceeds in the state where the lithium alloy is already formed on the negative electrode, thereby showing an effect of reducing initial irreversible phases.

  • Publication number: 20200075989
    Abstract: A method for manufacturing a negative electrode for a lithium secondary battery. A negative electrode for a lithium secondary battery is manufactured while forming a composite of lithium metal and a negative electrode active material through a rolling process In the case of the lithium secondary battery to which the negative electrode containing such a composite is applied, when the battery starts to operate, the negative electrode active material is pre-lithiated, and thus charging/discharging process proceeds in the state where the lithium alloy is already formed on the negative electrode, thereby showing an effect of reducing initial irreversible phases.

  • Publication number: 20110151429
    Abstract: The present invention relates to a bioprobe including a substrate and inorganic nanoparticles attached to the surface of the substrate, a method of preparing the bioprobe, and an analysis apparatus and method using the bioprobe. In the bioprobe according to the present invention, inorganic nanoparticles introduced to the substrate serve as a linker to which a target-specific substance such as an antibody can be bound, and they also increase the surface area of the substrate, thus increasing a surface area where a target substance to be detected can contact the substrate. In this regard, the bioprobe can be effectively used for detection, dosing, or analysis of various biomolecules or other chemical substances.
