Electrode assembly, and lithium ion electric roll using the electrode assembly
First Claim
1. An electrode assembly, comprising:
- a bare electric roll including a top portion formed at a terminal side thereof, a bottom portion formed at a side of the bare electric roll opposite to the terminal side, two first surfaces extending along a width direction and a length direction of the bare electric roll, and two second surfaces extending along a thickness direction and the length direction of the 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,wherein the anti-puncture cushion is arranged on each of the two second surfaces and extends to the two first surfaces, and covers an edge of the anode sheet, andwherein an edge of the anti-puncture cushion exceeds the bottom portion of the anode sheet.

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.
