In one aspect, a binder for an electrode of a lithium rechargeable battery, which increases adhesion between the electrode and an active material by saving characteristics of two monomers by grafting an acryl group to a vinyl alcohol group, and an electrode for a rechargeable battery comprising the same are provided. The electrode can improve charge and discharge cycle life characteristics of the rechargeable battery.

Binder for electrode of lithium rechargeable battery and electrode for rechargeable battery comprising the same

An electrode plate includes a current collector, the current collector being made of metal and having a 3-dimensional mesh structure, and an active material portion including an active material, the active material portion being inserted into a vacant space in the current collector and coated on top and bottom surfaces of the current collector.

Electrode plate, secondary battery having the same, and manufacturing method for the electrode plate

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.
