The present invention relates to a lithium secondary battery. The lithium secondary battery includes a positive electrode including a positive active material; a negative electrode including a negative active material; and an electrolyte including a non-aqueous organic solvent, a lithium salt, and an additive including a compound represented by Chemical Formula 1. The negative active material includes Si at about 0.1 wt % to about 32 wt % in amount based on a total weight of the negative active material. 

Lithium secondary battery comprising electrolyte

A battery pack includes a battery and a battery management system to control and manage charging and discharging of the battery. The battery management system includes an external terminal connected to a charger or an external electronic device, a cell terminal connected to the battery, a charge field effect transistor (FET) and a discharge FET connected between the external terminal and the cell terminal, a voltage sensor to measure a battery voltage of the battery, a comparator comparing the battery voltage with a reference voltage to determine whether the battery pack is in an overdischarged state, and a controller controlling the charge FET to be cut off to prevent a charge operation of the battery, if the comparator determines that the battery pack is in an overdischarged state.
