Abstract
The embodiments of the present application provides a wound electrode assembly formed by winding a first electrode sheet, a second electrode sheet, and an isolating membrane disposed therebetween. The wound electrode assembly includes: a first surface having a first protrusion in the thickness direction of the wound electrode assembly; a first wound electrode assembly; a second wound electrode assembly wrapping the first wound electrode assembly, the first wound electrode assembly and the second wound electrode assembly sharing the first electrode sheet and the second electrode sheet; an adhesive layer disposed between the first electrode sheet and the isolating membrane, and/or between the second electrode sheet and the isolating membrane. The purpose of the present application is at least to provide a wound electrode assembly capable of reducing the risk of misalignment of the internal structures of the electrode assembly during the falling, and retaining the shape of the electrode assembly.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
