Abstract: Provided is a technique capable of evenly smoothing powder supplied to the surface of a supply member. A powder coating apparatus includes a pair of press rollers, hoppers, and squeegee rollers disposed such that prescribed gaps are formed between the squeegee rollers and the press rollers, and adjusting thickness of the powder by smoothing the powder supplied to each outer circumferential surface of the press rollers. The powder coating apparatus presses the powder, smoothed by the squeegee rollers, between the press rollers to form compressed powder layers on both the surfaces of the web. The squeegee roller is formed in a column having an axis being parallel to the outer circumferential surface of the press roller and being orthogonal to a moving direction of the outer circumferential surface of the press roller.

Abstract: In a method of manufacturing a lithium-ion secondary battery electrode sheet proposed herein, a current collector (11), a powder material (13) of granulated particles, and a binder solution (12) are prepared. The binder solution (12) is applied onto the current collector (11). Subsequently, the powder material (13) of the granulated particles is fed onto the current collector (11). (Then, the powder material (13) of the granulated particles is pressed against the current collector (11). In the basic manufacturing method, adhesive strength of the powder material (13) of the granulated particles is enhanced after the powder material (13) of the granulated particles is fed onto the current collector (11) and before or while the powder material (13) of the granulated particles is pressed against the current collector (11).

Abstract: The present invention discloses a method of manufacturing a lithium-ion secondary battery electrode. The method includes the steps of: supplying composite particles (1), each containing an active material (2) and a binder (4), onto a sheet collector (42); and rolling the composite particles (1) supplied onto the collector (42), thus forming an active material layer (44). The rolling step includes a first rolling sub-step involving first rolling, and a second rolling sub-step to be performed after the first rolling sub-step. Rubber rolls (R1) are preferably used in the first rolling sub-step.

Abstract: The method for manufacturing an electrode for a lithium ion secondary cell proposed herein includes: a step of pattern-coating a binder liquid 21d on a current collector 12 and forming a binder coat layer 16, and a step of supplying granulated particles 32 onto the binder coat layer 16. The binder coat layer 16 is intermittently formed on the current collector 12 so that band-shaped coated portions 16a and band-shaped uncoated portions 16b are alternatingly adjacent to each other. The width t1 of the coated portions 16a, the width t2 of the uncoated portions 16b, and the average particle diameter R of the granulated particles 32 satisfy the following relationships: 0.53R≦t1≦10R; 0.66R≦t2≦10R; and 0.2≦t1/t2≦3.75.
