Abstract

A lithium secondary battery includes LiCoOcontaining excess lithium, or the like as an irreversible additive in a positive electrode, and at the same time, includes an electrolyte additive of Formula 1 having a specific molecular weight in an electrolyte to realize low battery resistance and effectively prevent metal ions from being exsolved from the irreversible additive, and thus has advantages of excellent battery performance and lifespan,
