Method of manufacturing lithium-ion secondary battery electrode sheet

A method for producing an electrode for lithium ion secondary batteries proposed herein includes: a step of forming a binder coat layeron a collector, with the binder coat layerbeing formed so as to have a large coat amount regionA of relatively a large coating amount and a small coat amount regionB of relatively small coating amount, and the large coat amount regionA being provided at both side edge portionsE of the binder coat layer; a step of supplying granulated particles containing active material particles and a binder, onto the binder coat layer; and a step of forming an active material layer by pressing of aggregates of the granulated particles.

Method for producing electrode for lithium ion secondary batteries

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.

A powder supplying device () includes a case () in which a storage portion () is formed for temporarily storing powder (), the case () having an inlet () formed in an upper end of the storage portion (), and a rectangular outlet () formed in a lower end of the storage portion (); a rotor () that is arranged in the case () and transports the powder () in the storage portion () to the outlet () by rotating; and a mesh body () through which the powder () that has been transported to the outlet () passes. The powder supplying device () supplies the powder () onto an upper surface of an electrode foil (). The rotor () has a brush-like shape, with a plurality of hair members () radially implanted pointing radially outward with an axial center (G) of the rotor () as the center.

Powder supplying device and electrode manufacturing apparatus

Provided is an apparatus for manufacturing an electrode for a lithium ion secondary battery that makes it possible to form a more uniform active material layer by using granulated particles. The manufacturing apparatus includes: a conveying mechanism, a supply unit, a squeegee, an adjustment unit, and rolling rolls. The conveying mechanism conveys a collector. The supply unit supplies granulated particles, including active material particles and a binder, onto the surface of the conveyed collector. The squeegee levels the supplied granulated particles. The adjustment unit is disposed upstream of the squeegee. The adjustment unit controls the accumulation height of the granulated particles accumulated upstream of the squeegee. The rolling rolls roll the leveled granulated particles and form the active material layer.
