Beschreibung
Zusammenfassung:	A lithium ion secondary battery including a compound containing at least one thiol group (-SH) in a molecule in a unit cell of the battery is provided. By including the compound containing thiol group (-SH) having good reactivity with copper or copper ions, the formation of dendrite through the reduction of copper ions present in the inner portion of the battery or produced during operating the battery at the surface of an anode may be prevented. The internal short between two electrodes due to the dendrite may be also prevented.
