Abstract
Official abstract text for this publication.
Provided is a binder for an electrode of a lithium rechargeable battery including a copolymer of Chemical Formula 1, which increases adhesion between the electrode and an active material by employing a copolymer based on polyacrylamide, while having excellent heat resistance and mechanical strength, an electrode for a rechargeable battery including the same, and a rechargeable battery including the electrode. The binder and electrode can improve charge and discharge cycle life characteristics of the rechargeable battery.
