Abstract
The present invention provides an electrode for an electrochemical device comprising: an electrode current collector; an electrode active material layer formed on a part of at least one surface of the electrode current collector, and comprising an electrode active material; a packed bed formed on non-coating areas of both sides of the electrode current collector, on which the electrode active material layer is not formed, coated to be continuous with the electrode active material layer, and comprising a mixture of a first inorganic particles and a first polymer binder; and a separation layer formed simultaneously on the surfaces of the electrode active material layer and the packed bed, and comprising a mixture of a second inorganic particles and a second polymer binder.
