▎ 摘  要

NOVELTY - The electrode (300) has an electrode active material layer (100) comprising an active material and a binder. An electrode current collector (200) is provided on a surface or between opposite surfaces of the electrode active layer. An interlayer (250) is provided between the active layer and the current collector, where a ratio of change of vertical relative force (FVR) between a point, which is 5% away from the surface of the material layer, and another point with respect to total thickness of the layer, is 300% or less when the layer is measured by a surface and interfacial cutting analysis system (SAICAS). USE - Electrode for use in a lithium battery (claimed) and electrochemical battery. ADVANTAGE - The electrode is capable of preventing or reducing deterioration of lithium battery performance. The electrode has a substantially uniform distribution of constituents within the electrode, such that its performance is enhanced or suitable. The performance of a lithium battery utilizing such an electrode is deteriorated. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) lithium battery; and (2) method of manufacturing an electrode (300). DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the electrode. Electrode active material layer (100) Electrode current collector (200) Interlayer (250) Electrode (300)
