摘要： A wound bare electric roll includes a cathode sheet, an anode sheet and a separator, the separator being arranged between the cathode sheet and the anode sheet. The cathode sheet has an end and an anti-puncture cushion arranged on a tail exposed zone at the end of the cathode sheet. The anti-puncture cushion corresponds to an outer surface of a corner of the anode sheet. A lithium ion battery has a laminated aluminum film, and a wound bare electric roll accommodated in the laminated aluminum film.
