Disclosed is a lithium secondary battery. The lithium secondary battery includes a cathode, an anode, a separator and a non-aqueous electrolyte solution. The separator includes a porous substrate, and a coating layer coated on at least one surface of the porous substrate and including a mixture of inorganic particles and a binder polymer. The non-aqueous electrolyte solution contains an ionizable lithium salt, an organic solvent, and a dinitrile compound having a specific structure. The lithium secondary battery is very safe without side reactions of the electrolyte solution. Therefore, the lithium secondary battery exhibits excellent cycle life and output performance characteristics.

The present invention relates to a precursor of positron emission tomography (PET) radioactive medical supplies, a preparation method thereof, and an application thereof, and more specifically, to a precursor having a tetravalent organic salt leaving group, a preparation method, and a method for preparing desired PET radioactive medical supplies in a high radiochemical yield within a short preparation time by introducing 18F using the same through a single step. The precursor having a tetravalent organic salt leaving group of the present invention can simplify the known complex multistep preparation of radioactive medical supplies into a single step, can save production costs because an excessive amount of a phase transfer catalyst is not required, facilitates separation of a compound after reaction, and enables rapid reaction velocity. The features are appropriate for the mass production of PET radioactive medical supplies by an automated synthesis system.

Disclosed is a lithium secondary battery. The lithium secondary battery includes a cathode, an anode, a separator and a non-aqueous electrolyte solution. Either the cathode or the anode or both include metal oxide coating layers on electrode active material particles forming the electrode or a metal oxide coating layer on the surface of an electrode layer formed on a current collector. The non-aqueous electrolyte solution contains an ionizable lithium salt, an organic solvent, and a dinitrile compound having a specific structure. In the lithium secondary battery, degradation of the electrode is prevented and side reactions of the electrolyte solution are inhibited. Therefore, the lithium secondary battery exhibits excellent cycle life and output performance characteristics.
