Abstract

See full text

An electrode including a current collector; and an electrode active material layer disposed on at least one surface of the current collector is disclosed. The electrode active material layer includes a lower layer region facing the current collector, and an upper layer region facing the lower layer region and extended to the surface of the electrode active material layer. The lower layer region includes a first active material and a first non-rubbery binder and is free from a rubbery binder. The upper layer region includes a second active material, a second non-rubbery binder, and a rubbery binder. The rubbery binder is a hydrogenated nitrile butadiene rubber (H-NBR). Each of the first non-rubbery binder and the second non-rubbery binder includes a polyvinylidene fluoride (PVDF)-based polymer, and the weight ratio of the second non-rubbery binder to the rubbery binder in the upper layer region is 1:0.03-1:0.07.
