Abstract
The present invention relates to a binder for a secondary battery electrode, a secondary battery electrode composition including the binder, and a secondary battery using the same. The binder includes a copolymer having a polyvinyl alcohol (PVA) and an ionically substituted acrylate. The binder may have an excellent electrode adhesive force, prevent an electrode deformation caused by the expansion and contraction of an electrode active material, and improve charge/discharge life characteristics, and further, simplify manufacturing processes.
Claims17
