摘要： Disclosed is a positive electrode material for a lithium secondary battery. The positive electrode material includes a positive electrode active material formed of Li—[Mn—Ti]-M-O-based material including a transition metal (M) to enable reversible intercalation and deintercalation of lithium and molybdenum oxide. The positive electrode active material is coated with the molybdenum oxide to form a coating layer on a surface thereof

摘要： A method for checking defects in a lithium ion secondary battery includes primarily charging and degassing the lithium ion secondary battery after manufacture of the secondary battery, secondarily charging and discharging the secondary battery and then measuring one or more of OCVs and IRs of lithium ion secondary battery cells; pressurizing and aging the secondary battery by aging the secondary battery in a state in which a pressure of a designated magnitude or more is applied to the secondary battery, and checking whether or not the secondary battery cells are defective by re-measuring the one or more of OCVs and IRs of the secondary battery cells and then comparing the re-measured one or more of the OCVs and the IRs to the previously measured one or more of the OCVs and the IRs.

摘要： Disclosed are a method for checking defects in a lithium ion secondary battery and a lithium ion secondary battery manufactured thereby. The method includes primarily charging and degassing the lithium ion secondary battery after manufacture of the secondary battery, secondarily charging and discharging the secondary battery and then measuring one or more of OCVs and IRs of lithium ion secondary battery cells; pressurizing and aging the secondary battery by aging the secondary battery in a state in which a pressure of a designated magnitude or more is applied to the secondary battery, and checking whether or not the secondary battery cells are defective by re-measuring the one or more of OCVs and IRs of the secondary battery cells and then comparing the re-measured one or more of the OCVs and the IRs to the previously measured one or more of the OCVs and the IRs.
