ABSTRACT:
The present invention provides a lithium ion polymer battery comprising an electrode having excellent adhesion and electrical conductivity between a current collector and an active material layer, cycle capacity maintaining characteristics being improved, wherein a bonding layer, which bonds the current collector to the active material layer, is stable to an organic solvent in an electrolytic solution and is excellent in storage stability, and also, it is made possible to suppress the corrosion of the current collector by a strong acid such as hydrofluoric acid generated in the battery.
