Abstract:
The present application relates to the filed of energy storage devices, and in particular, relates to a cathode sheet and a lithium ion electric roll using the cathode sheet. The cathode sheet comprises a cathode current collector, an active substance layer, a cathode tab, a head protective adhesive, a tail protective adhesive, an ending adhesive, and an anti-puncture cushion. The cathode current collector comprises a head exposed zone, a head adhesive application zone, a coating zone, a tail adhesive application zone, and a tail exposed zone. The active substance layer covers the coating zone, the head protective adhesive covers the head adhesive application zone, the tail protective adhesive covers the tail adhesive application zone, the ending adhesive is bonded to a tail of the tail exposed zone, and the anti-puncture cushion is connected to the tail exposed zone.
