Abstract
The present application relates to the filed of an energy storage component, and in particular, relates to an electrode assembly, and a lithium ion electric roll using the electrode assembly. The electrode assembly comprises a bare electric roll and an anti-puncture cushion; wherein the bare electric roll comprises at least one electrode unit, the electrode unit comprising a cathode sheet, an anode sheet, and a separator, wherein the cathode sheet is isolated from the anode sheet by the separator; and the anti-puncture cushion is arranged on two sides along a width direction of the bare electric roll, and covers an edge of the anode sheet. A lithium ion electric roll comprises a laminated aluminum film and the electrode assembly, wherein the electrode assembly is wrapped by the laminated aluminum film.
