NOVELTY - An electrode (100) consists of a porous coating layer (130) having a thickness deviation given by a specific relationship. The electrode consists of a current collector (110), and an active-material layer (120) formed on the surface(s) of the collector, and containing a composition comprising active material particles and binder polymer (I), and a composition comprising inorganic particles and binder polymer (II) formed on the surface of active-material layer.    USE - Electrode is used as anode or cathode in electrochemical device e.g. lithium secondary battery (all claimed). Uses include but are not limited to electric vehicles, cellular phones, camcorders, and notebook computers.    ADVANTAGE - The electrode can be manufactured using a method for simultaneously drying the active-material layer and porous coating layer, preventing binder polymer of porous coating layer from infiltrating the active material layer to impart excellent quality to the electrode. The uniform formation of porous coating layer contributes to the stability of battery.    DETAILED DESCRIPTION - An electrode consists of a porous coating layer having a thickness deviation given by a specific relationship. The electrode consists of a current collector, and an active-material layer formed on the surface(s) of the collector, and containing a composition comprising active material particles and binder polymer (I), and a composition comprising inorganic particles and binder polymer (II) formed on the surface of active-material layer. The thickness deviation is given by, (Tmax-Tmin)/Tavg=0.35 or less, where Tmax is the maximum thickness of the porous coating layer formed on the surface of active-material layer, Tmin is the minimum thickness of the porous coating layer, and Tavg is the average thickness of the coating layer, when sections of the porous coating layer are observed using an electron microscope. An INDEPENDENT CLAIM is included for manufacture of electrode.    DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the electrode.
