Secondary battery with protective circuit board and secondary protective element

摘要

A secondary battery with a protective circuit module including a rechargeable bare cell having a first electrode and a second electrode and a protective circuit board having a protective circuit for the rechargeable bare cell. A conductive bonding layer is located on the protective circuit board and a secondary protective element assembly is attached to the protective circuit board by the conductive bonding layer. A first lead plate electrically connects the secondary protective element assembly to the first electrode, and a second lead plate electrically connects the protective circuit board to the second electrode.
