Abstract: An electrode sheet includes a current collector as well as an insulating layer and an active material layer arranged on the current collector along a first direction, the insulating layer is first formed on the current collector, and then the active material layer is formed on the current collector, so that an edge portion on one side of the active material layer close to the insulating layer covers a first edge region of the insulating layer.

Abstract: A coating apparatus, and an electrode plate production system and method are provided, where the coating apparatus includes a roller capable of rotating around its axis. The roller includes: a body portion; and a protrusion portion disposed on an outer surface of the body portion and extending along an entire circumference of the body portion. A surface of the protrusion portion located on an outermost side in a radial direction of the body portion serves as a coating surface.

Abstract: Embodiments relate to a coating system. A substrate includes a first coating region and a second coating region adjacent to the first coating region. The coating system includes a first gravure mechanism and a second gravure mechanism, where the first gravure mechanism is configured to apply a first functional layer onto the first coating region, and the second gravure mechanism can receive the substrate having the first functional layer and apply a second functional layer made of a material different from that of the first functional layer onto the second coating region. In the coating system, with provision of first gravure mechanism and the second gravure mechanism, when the substrate is continuously transported in a same direction, the two functional layers made of different materials can be sequentially applied onto corresponding regions of the substrate.

Abstract: An anilox roller and a coating apparatus are provided. The anilox roller includes a roller body and an annular boss formed on a surface of the roller body. The annular boss extends in a circumferential direction of the roller body. The annular boss includes a circumferential surface, a first side surface, and a second side surface. The first side surface and the second side surface face each other in an axial direction of the roller body. The circumferential surface connects the first side surface and the second side surface, and the circumferential surface includes an anilox region having an etched anilox. A first blank region without an etched anilox is arranged between the anilox region and the first side surface.
