ELECTRODE FOR AN ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL DEVICE HAVING SAME

摘要

The present invention relates to an electrode for an electrochemical device, comprising: an electrode collector; an electrode active material layer formed on at least a portion of one surface of the electrode collector, and including an electrode active material; a filling layer formed on uncoated parts of both sides of the electrode collector on which the electrode active material layer is not formed, coated to be continuous with the electrode active material layer, and including a mixture of first inorganic material particles and a first polymer binder; and a separation layer formed simultaneously on the surfaces of the electrode active material layer and the filling layer, and including a mixture of second inorganic material particles and a second polymer binder. The electrode for an electrochemical device of the present invention includes a filling layer that is continuous with an electrode active material layer in order to facilitate the coating of a separation layer on the entire surface of the electrode active material layer. Also, because the electrode active material layer is not externally exposed even after the separation layer is coated, stability of the electrochemical device can be ensured.
