Abstract
A lithium secondary battery includes a thick-film negative electrode having a current density of about 4.0 mA/cm2 to about 7.0 mA/cm2 and a low-viscosity electrolytic solution having a viscosity of about 3 cP or less. Since the electrolytic solution includes a propionate-based ester compound, impregnation of the electrolytic solution in electronic devices having a thick-film negative electrode and lifespan characteristics of the devices may be improved.
