Provided are a dry binder including a crosslinking reaction product in which a polyurethane-based polymer is crosslinked by an epoxy crosslinking agent, an electrode including the dry binder, and a rechargeable lithium battery including the dry binder.
Claims18
A dry binder, comprising:
- a crosslinking reaction product in which a polyurethane-based polymer is crosslinked by an epoxy crosslinking agent.
A method for manufacturing an electrode, the method comprising:
- mixing an electrode active material, a binder, and a conductive material in a dry manner to prepare a composition for forming an electrode, and
- coating the composition for forming the electrode on an electrode current collector to form an electrode,
- wherein the binder comprises a crosslinking reaction product in which a polyurethane-based polymer is crosslinked by an epoxy crosslinking agent.
