Patent ID: 8551633

Claim:
A secondary battery comprising: an electrode assembly comprising a first electrode plate and a second electrode plate that are rolled while having a separator interposed therebetween; and a finishing member positioned adjacent a periphery of the electrode assembly so as to be positioned proximate a roll end of the electrode assembly wherein the finishing member comprises an insulating layer, a conductive layer, a ceramic layer and an adhering layer wherein the insulating layer is formed on an outermost part of the finishing member so as to cover the conductive layer; and wherein the ceramic layer and the adhering layer are interposed between the conductive layer and the electrode assembly with the adhering layer contacting the electrode assembly; wherein the finishing member comprises a conductive layer having a first end that forms a conductive contact with a roll end of the first electrode plate by the first end overlapping the roll end the first electrode plate and that is disposed to face a roll end of the second electrode plate wherein, at the roll end of the electrode assembly, the second electrode plate extends further than the first electrode plate and the separator extends further than the second electrode plate wherein the finishing member is attached to the periphery of the electrode assembly so as to be positioned proximate an end of the separator.
