Provided are an anode for a secondary battery including an anode collector, an anode active material coated on the anode collector, and a non-coating portion (anode tab) which protrudes from one side of the anode collector and is not coated with an anode active material, wherein the anode includes a metal member which is bonded to the non-coating portion and has higher reactivity or reducibility with respect to a metal oxide than the anode collector, and a secondary battery including the anode.

Anode for lithium secondary battery and lithium ion secondary battery including the same

A lithium ion secondary battery including a compound containing at least one thiol group (&#x2014;SH) in a molecule in a unit cell of the battery is provided. By including the compound containing thiol group (&#x2014;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.
